raymond mill

The main shaft is one of the main components of the Raymond mill. Sometimes the shaft deformation phenomenon occurs during use. When this phenomenon occurs, it is necessary to find out the cause and give a solution. Next, let us come to the Raymond mill to process the limestone main shaft deformation.1. The particles of the feed are too large. After the material enters the interior of the Raymond mill, it will directly contact the spindle. If the particles of the material are too large, and the number of collisions with the spindle is much higher, the spindle will be deformed. . Therefore, we must control the particles of the material when feeding the Raymond mill, not too large.2. The time for overloading the Raymond mill is relatively long. Any machine will cause some adverse effects on the Raymond mill after overloading. The overloaded work will inevitably increase the working pressure of the main shaft, which will aggravate the wear of the main shaft and slowly cause the main shaft to deform. Therefore, you must avoid overload work when you work.3. The phenomenon that the main shaft has rust is not treated in time, and the main shaft is rusted. When the Raymond mill is running, some rust and materials will be mixed together, and the fineness of the finished product will be reduced. Moreover, the strength of the main shaft is lowered due to rust, which is very serious, and causes the Raymond mill to operate unevenly. Therefore, we must diligently check the use of the spindle, and what is wrong should be repaired immediately.4. During operation, metal particles enter the interior of the Raymond mill. During operation, the metal particles will collide with the spindle, causing the spindle to deform. We must ensure that the Raymond mill feeds. No impurities.

Raymond mill has three types: 3 rollers Raymond mill, 4 rollers Raymond mill and 5 rollers Raymond mill. So the figure represents the number of grinding rollers. That means 3 roller Raymond mill has 3 grinding rollers, 4 rollers Raymond mill has 4 grinding mills, and 5 rollers Raymond mill has 5 grinding mills.Beside the number of grinding rollers, the discrepancy between the different types Raymond mill is the detail production specifications, such as output size and capacity. Compared to the other two types, 5 rollers Raymond mill has finer output size and larger capacity. After all, 5 grinding rollers grind with more power. But 5 rollers Raymond mill price is higher than the other two types. 3 rollers Raymond mill is the common raymond mill with small and medium capacity. Its output size can be 0.613 – 0.044 mm, or 30 – 325 meshes, which is enough for ordinary power grinding. 

Problems that are easy to overlook in Vertical roller mill productionA few problems that are easy to ignore in Vertical roller mill's production can reduce Vertical roller mill's production and make Raymond wear a lot of wear and tear:1, material composition, Raymond slow before powder material containing fine powder in the more the impact Vertical roller mill powder, because these fine powder easy adhesion effect delivery for fine powder content more should in advance through a sieve.2. The humidity of the material, that is, when the moisture in the material is large, the materials are easy to adhere to in Vertical roller mill and easy to clog during the feeding process, resulting in the reduction of Raymond's grinding ability.3. The abrasion resistance of the main parts (grinding roller, grinding ring) of Vertical roller mill is greater, and if it is not wear-resistant, it will affect the ability of Vertical roller mill powder.4. According to the hardness of the material. The harder it is, the harder it becomes, and the harder it is to wear. Raymond grinds at a slow speed, of course Raymond grinds small.5. Viscosity of materials. The more viscous the material is, the easier it is to stick to it.6. The fineness of the material after the grinding of Redmond powder requires high degree of fineness. The thinner the material required to be polished by Raymond, the smaller the ability of Vertical roller mill powder.

In order to achieve the purpose of desulfurization, dephosphorization and slag removal, the raw materials of limestone require: low S content (less than 0.015%); High activity degree ( 350mL); The particle size control is 0.01~ 1mm; The surface passivation ensures good ductility and fluidity to overcome the disadvantages of easy moisture absorption, hard storage and transportation. In addition, the commonly used by refining outside the furnace injection spray lime powder metallurgy method, also requires fine lime powder particle size and uniform, and active degree is high, waterproof, low content of S and surface passivation, facilitate storage transport.For hot metal pretreatment and refining outside the furnace process requirement for lime powder in use in the process design processing lime powder pulverizing equipment, here are several pulverizing equipment of pulverizing effect are introduced and compared.limestone Raymond millThe limestone Raymond mill is also called suspension roller mill or pendulum mill. It is commonly used for grinding fine equipment, which is mainly used in metallurgy, building materials, chemical industry, mining and other mineral materials. Powder grinding range is a variety of non-flammable and explosive materials with a hardness of less than 7. The size range of grinding finished product (0.125 ~ 0.04mm, i.e., 100 eyes ~325 eyes, which can reach 500 items) is adjusted according to different requirements. The limestone Raymond mill is mainly composed of main engine, analyzer, fan, product cyclone separator, micro-powder cyclone separator and duct.Raymond mill works: limestone grinding machine allows feed particle size of the block material, the uniform feeding device continuously into the host, grinding, grinding powder by blower after circulation wind flow, with the analysis on the host at the top of the machine for grading. The fine - sized powder will enter the large cyclone collector with the air flow, and the finished product will be discharged after collecting. The air flow from the upper end of the large cyclone collector flows into the blower, and the entire wind system is closed loop, and most of it flows under negative pressure.Because of the moisture in the mill materials, the vaporization of vaporization into the gas during grinding and the gas leaking into the air ducts under negative pressure in the whole air duct, resulting in the increase of wind volume in the circulation wind road. This increase of air volume, from the blower and the main engine intermediate wind tube into the small cyclone collector. With the current and the wind, a few fine powders are brought into the atmosphere. After being collected by a small cyclone, it is discharged by another pulverized tube, which is discharged into the atmosphere by the exhaust pipe at the top of the small cyclone collector.The structure features of limestone Raymond mill: the three-dimensional structure is small and the whole set is strong. From the block, it is expected that the finished product can be independently produced into a production system. The fine uniformity of finished product and 99% of the screening rate are difficult to be found in other mill equipment. The transmission device adopts sealed gearbox and belt wheel, which is stable and reliable. All the important parts are made of high quality steel, the wear-resistant parts are high performance wear-resisting material, the whole machine has high wear resistance and reliable operation. The electric system adopts the centralized control, the grinding workshop can realize the unattended operation, and the maintenance is convenient. It is worth noting that feed capacity is more sensitive in limestone Raymond mill, if the feed is insufficient, the equipment running under load, will have a bigger noise, and the equipment main body and the vibration of the equipment foundation to produce significantly.The investigation found that some of the manufacturers who used limestone Redmond to grind lime powder had removed one of the suspension rolls and some had removed the cyclone. The main reason is: the water content of the raw material lime itself is low, the steam produced in the grinding process is small, and the influence on the air pressure inside the mill is small. The required finished lime only requires that the particle size reach a certain range (usually

For the production process of Raymond Mill, no matter which type of mill is selected in the production, it must ensure its reasonable material feeding property. Otherwise, it will increase the difficulty of production and cause the efficiency to drop, even the damage, aging, etc. For the equipment, then what kind of materials can be processed for the machine?First of all, Raymond mill can process materials with Mohs hardness below seven, humidity below 6%, and is non-flammable and explosive ore. In addition, the required feed size is between 20-30 mm. It can be seen that the hardness of the material that can be processed by the machine can not be greater than 7, and can not be greater than 6%, and it is non-flammable and explosive. In addition, the feed size can not be greater than 30 mm, not less than 20 mm, to meet these requirements. The raw materials can be processed using a Raymond mill, otherwise the machine cannot be processed.For example, if the hardness of the material added to the interior of the Raymond mill is greater than 7, then the difficulty of grinding increases during processing, which not only causes a decrease in efficiency, but also causes an increase in wear of internal parts, and if humidity If it is more than 6%, then inside the machine, the materials will stick together, which will cause blockage. This is also an important reason for the decline of equipment efficiency. Similarly, materials that do not meet other requirements are added to Raymond mill. Internally, it will also cause changes in production results, which is why the nature of the feed is better than the requirements of the mill.

The Raymond mill is a new type of stone crusher which is produced on the basis of the domestic and foreign Raymond Mill combined with the advanced milling technology. The Raymond mill has the advantages of impact breaking and hammer breaking. The Raymond mill is mainly used for small and medium sized mill cement clinker for building sand, iron ore, sandstone, gypsum, coal and other minerals in hard milling. The utility model has the advantages of large milling ratio, low energy consumption, stable operation, simple structure, convenient operation and maintenance, etc.. The Raymond Mill truly implements a multi-purpose, high efficiency, low cost features.The Raymond mill structure characteristics1. the Raymond mill can effectively deal with a large amount of moisture content of the material to prevent the blockage of Raymond mill.When the water content of the material is too large, the feed chute and the counter plate of the Raymond mill can be equipped with a heating device to prevent the material from sticking. Raymond Mill does not have to be equipped with the bottom sieve plate can effectively prevent clogging. The hammer can not be used to prevent the heating of the material to be bonded, and must be equipped with the bottom of the sieve plate, increasing the possibility of blockage.2. Raymond mill is not only suitable for soft materials but also for materials with very high hardness.The plate hammer of the Raymond mill is firmly fixed on the rotor by a mechanical clamping structure. Compared with the superfine Raymond mill, the rotor of the Raymond mill has a greater momentum, which is suitable for the material with more hard milling.3. the Raymond mill can be conveniently and flexibly adjust the material size, wide range of adjustment.The Raymond mill can be adjusted in several ways to deal with the particle size, flexible method to adjust the gap between the hammer and the grinding chamber. Also is to adjust the rotor speed.4. because of the unique structure design of the Raymond mill, the wear parts of the Raymond mill are smaller than that of the superfine Raymond mill and the material utilization ratio is high.The abrasion of the plate hammer of the Raymond mill is only on the side of the facing material. When the Raymond mill is in normal operation, the material is crushed by the hammer plate, and the back and side surfaces of the plate hammer are not worn. The utility model has the advantages of high metal utilization ratio of 45% to 48%, which can not be compared with General Raymond mill.5. the Raymond Mill spare parts replacement is simple, maintenance costs are reduced accordingly.The Raymond mill is provided with six plate hammers which are convenient to replace, save the maintenance time and improve the production efficiency.

How to repair the Raymond mill in the event of failure, the general operator is difficult to complete for such technical problems, and the problem of mill failure is inevitable in the operation of the equipment. The following small series summarizes the four major maintenance techniques for reference. These include preventive maintenance, fault repair, production maintenance, and predictive maintenance.First, preventive maintenance, develop detailed plans for the operation of milling equipment, including production volume, schedule, professional maintenance department, etc. Reasonable work arrangements and preventive measures can extend the service life of equipment and accessories and improve production efficiency. The following points:1. Develop a reasonable production plan to avoid overworked equipment.2. Set up a special maintenance department to check regularly and find out that the abnormal quality of finished products and production efficiency are eliminated in time.3. Lubricate or replace worn or severely worn parts.Second, fault repair refers to the unplanned maintenance that is taken when the Raymond mill fails or the performance is degraded. It is a behavior that solves the fault more specifically. For example, the powder collector does not produce powder, the bearing locks, and the feed port Dust abnormalities, etc., such common faults Zhengzhou General Mine has a detailed technical description of the grinding equipment, and the fault problem can not be handled at will, to find a technician or to know and eliminate it under the knowledge of the technician, and the whole process of troubleshooting Under power failure conditions to avoid other accidents.Third, production maintenance mainly refers to the elimination of production planning problems, the production can not keep up, the finished products are not up to standard, etc. There are two possible failure factors: one is the performance of the equipment itself, and the other is the level of the operator. There is no quality problem. The factors affecting the quality of the later-grown grinding equipment are much smaller. The maximum may be caused by the operator. For example, it is impossible to control the uniform feeding, the startup shutdown sequence is incorrect, and the valves are open, such as lock powder. Poor sealing of the device will result in less or no powder, low yield, uneven feeding will affect the uniformity of the finished product, and blockages have occurred.Fourth, predictive maintenance, and prevention and maintenance have similarities, but there are essential differences, prevention is all possible problems, but the substance does not necessarily occur, and the prediction has already occurred, has been predicted to varying degrees, but has not yet Cause serious consequences. Predictively, according to the information provided by the state monitoring and diagnostic technology, necessary and appropriate maintenance can be carried out before the failure occurs. Most skilled operators can find potential faults in advance through the sound and finished product status, so as to prevent and control early.The failure of Raymond mill is a problem that all customers will face. Whether you are buying a brand manufacturer's mill or a small and medium-sized machine, the ore crushing equipment will wear, corrode, deform, burn, etc. during long-term use. Influencing efficiency and normal use, when the failure occurs, it is necessary to stop the production elimination problem. In addition, Zhengzhou General reminds everyone to pay attention to three points:(1), the purchase of equipment is to prepare a set of wearing parts, such as grinding rolls, grinding rings, blades, bearings, etc., in order to cause wear parts of the wearing parts without the use of accessories and delay production, and the price of such accessories is not high, 500 It takes a few hours to renew, and it is necessary to keep a spare part.(2) It is best to cooperate with the operator when replacing the parts or troubleshooting, so that the operator can better understand the principle of the equipment, and completely eliminate other equipment failures. If necessary, the equipment can be trained by the operator.(3) Maintenance is indispensable in the grinding production line, but the maintenance is also important. The maintenance of the three points depends on the importance of maintenance. The lubrication of the transmission parts and the replacement of the wearing parts are two important points. The choice of lubricant must be in accordance with the equipment instructions, including the type of lubricant, the amount of addition, and so on.

As Raymond mill in grinding equipment, the fineness of performance determines the characteristics of Raymond mill. Therefore, experts believe that the quality of Raymond mill Raymond Mill is to ensure the smoothness of the process equipment equipment for a long time. Customers to purchase Raymond mill equipment, we must pay particular attention to the fineness of processing Raymond mill.Using the powder fineness of properties determines the Raymond mill. Good Raymond mill is a powerful guarantee for the fine powder. Finesse test is an experimental work to characterize the fine powder by special instruments and methods. In different applications, the requirements of the powder properties are different. In all the powder properties index, fineness distribution is an indicator of greater attention in all areas. Thus, the distribution of the fine powder reflects the objective reality is a very important job.Many test methods of the fineness of powder. According to statistics, there are hundreds of varieties. The most commonly used methods of the settlement method, laser method, screening method, the method of the image and the resistance method to five. There are also several commonly used in specific industries in the field of test methods. The precision and finer test. He came of Raymond mill equipment manufacturing companies.Raymond Mill disposable product fineness can reach D975m. Whether you choose this type of series Raymond mill, controlling the fineness of free treatment 300-3000 mesh. The material Tongse rate reached 97%. Raymond mill cavity with innovative design. No, no rolling bearing screws. So there is no rolling mill Raymond and seals bearing problems, there is no loosening of screws and damage to equipment.

Raymond mill as the main grinding equipment for ore dressing production line and flotation production line, has high grinding efficiency, can be used for dry grinding and wet processing, and can be used for grinding of ceramics, bauxite and other minerals. When purchasing equipment, the focus of attention is on the quality and price of the equipment. How much is the price of the mine Raymond mill?1. general users in the investment purchase Raymond mill equipment, the price comparison process only see in front of the front, here to correct, in consideration of the price of Raymond mill, the initial investment is only a part, the later cost also need to join the calculation, so that the overall price of Raymond mill.2. the price and the level of Raymond mill are usually closely related to the following factors. First of all, the quotation of Raymond Mill in the factory area is analyzed in recent years. Although many manufacturers of Raymond mill are all over the area, the price of Henan Raymond mill is still lower than that of the manufacturer of Raymond Mill on the premise of quality assurance; in addition, the price of the same-sex factory is different from the Raymond mill. The middleman quotations are generally higher, and the direct manufacturers offer cheaper prices, and the big manufacturers will also make up their specific prices, which include only the single price of the mill equipment, or the maintenance and installation costs that may be involved in the later period. This will be more specific to the users, which are more conducive to the investment of the users, such as the world state. Industrial Science and technology group is quoted in this way; second is the influence of market condition on equipment price, when the market competition is fierce, the range of price selection is more space, and the price of unit Raymond mill equipment will be a little more expensive when the market is in short supply; after that, the influence of the mill equipment itself on its price is large. Small, quality, old and new, etc., but here is much more.
