stone grinding mill price factor1, the brandThere are many brands of stone grinding mills on the market, and the prices are becoming more and more diversified. The prices of different brands of stone grinding mills vary greatly, even the same type of stone grinding mills produced by the same manufacturer. The price will vary greatly. Because the specifications are different, the price is different. The stone grinding mills of different specifications will have some differences in labor cost and material cost, so the price will be different. Stones of different specifications will be different. The machine has different processing capabilities, power, finished product granularity, external dimensions and other parameters, users must choose to meet their own production requirements.2, manufacturersThe price of the stone grinding mill produced by each manufacturer is different. Users need to consult a specific manufacturer to know the specific price. Red Star produces a variety of stone grinding mills. The cheaper ones are small ultra-fine mills. Because the company provides customized production, the price per user is different. The specific price information needs online consultation. Our customer service staff, because the company needs to know the user's specific address in order to quote, because the freight of the equipment is also a part of the total price. The "Red Star" stone grinding machine produced by the company is an old brand and more worthy of users' trust.
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.
If it refers to the desulfurization in power plants, the data shows that 325 mesh limestone powder is mostly the best choice.And limestone Raymond mill can meet such requirements.As for the machine price, it also cannot be separated from the capacity needs. Manufacturers of limestone Raymond mill often can provide different models limestone grinding mills to satisfy the clients’ needs.The proper way is to get in contact with the supplier and get the actual quotation.
I would like to change this title to what is the difference between barite and limestone firstly before answering this question.This is the basic introduction of baryte and limestone from Wikipedia.Since they are different in several aspects like their hardness, moisture and etc, the suitable grinding machine for them may have a little difference.In general, manufacturer who produce barite and limestone grinding mills will give them a same name.Grinding mills for many ores will be classified into coarse powder mill and ultra fine powder mill. This results from the finished powder fineness.Now, there are two main different kinds of mineral (powder) grinding mills in the market.One is the well-known Raymond mill, which produced by our company can grind the ore into powder with 30 to 425 mesh.
The barite powder making process is relatively simple, and the milling process is roughly divided into: material→feeding→crushing→lifting→grinding→grading→collection, etc. The specific steps are as follows:First, the bulk barite material is crushed by a jaw crusher; then it is fed into the silo from bottom to top by the bucket elevator, and then uniformly and quantitatively fed to the Raymond mill by the electromagnetic vibrating feeder. The machine is fully ground; the crushed barite powder will be classified by the analysis machine and the blower, and the unqualified fine powder will be sent back to the main machine for re-grinding; after classification, the powder meets the fineness requirement. It will be separated into the dust collector with the pipeline device, and finally sent to the finished silo, and the packaging truck can be loaded with the powder tanker.whatsapp: 8618001642498
Barite grinding mill, also can be called barite powder grinding mill.This kind of machine is produced to grind the barite stone into fine powder, so as to expand its applicable fields in the market.According to your different expectation of the finished barite powder fineness, there are three commonly used barite grinding mills.The first one is Raymond mill, which can get 50–425 mesh barite powder.The second one is also be widely put into actual use in many countries-barite ultra fine powder grinding mill. This barite powder processing plant can produce the barite powder with 200 to 2500 mesh. This kind of grinding equipment produced by different companies can be a little different. Shanghai Clirik Machinery has been devoted to such industry for several years. There are five different models of main grinding units in barite powder processing plant. Each of them works under different electricity current.Barite ultra fine powder vertical grinding mill is a new product. Compared with the former two mills, this machine performs better both in capacity and finished powder fineness.If you want to get more details, you can talk with me.whatsapp: 8618001642498
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
According to the unique physical and chemical properties of limestone, the grinding mill manufacturer has introduced a limestone grinding machine specially designed for limestone powder processing. The limestone grinding machine mill is a kind of mining mill, mainly used for processing as limestone Ore products.Limestone is widely distributed in the world and has abundant reserves. It is a valuable resource for a wide range of uses. It is commonly used as a building material and is an important raw material for many industries. It can be used as a production of Portland cement to produce coated grade heavy calcium carbonate products ; as a filler in the production process of plastics and coatings; as a casting sand for the production of machinery.The limestone grinding machine is mainly composed of a main machine, an analysis machine, a blower, a finished cyclone, a pipeline device, a motor, etc., wherein the main body is composed of a frame, an inlet volute, a blade, a grinding roller, a grinding ring, a casing and a motor. The auxiliary equipment includes jaw crusher, bucket elevator, electromagnetic vibration feeder, electric control cabinet, etc. Users can flexibly choose according to the site conditions.
Stone grinding machine is a kind of mining equipment,which is used to grinding stone lump（pls note:not large stone! Generally we need stone crusher to crush large stone to small pieces at first) to stone powder.The main types of stone grinding machines:Hammer Mill:we usually called it coarse grinding mill. In fact it can also be classified as a crusher,named hammer crusher. The finished size less than 3–8 mmRaymond Mill: finished size:50-400 meshUltrafine Powder Grinding Mill:300-2500 meshVertical Roller Mill:1250-3000 meshOther Mills like Ball Mill, Jet Mill and so on.In addition to the finished size, you can also choose the machine based on the output capacity.
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 barite Raymond mill is often used for the grinding of minerals. I think everyone will think of 4R, 5R and 6R when they think of Raymond mill equipment. So what does this R mean?
