As much as I know from the industrial point of view a micro pulverizer mill is a sort of grinder that crushes different types of materials such as coal, plastic into less than 5mm particles that is applicable across a number of industries such as pharmaceuticals, material, metallurgy and sometimes food. And particularly, the perlite micro pulverizer is for grinding the perlite into fine powder that is high in demand for the construction industry.
Though prior to making any purchase if I were in your place would have ensured the resistance, efficiencies and durability. However, If you are looking for an easy purchase of a perlite micro pulverizer mill I can suggest you some online B2B platforms like; Alibaba, eWorldTrade, aliexpress, IndiaMart. From where you can easily source these mechanical devices. Other than online sourcing you can contact with independent retailers as well.
