A senior researcher at the Udmurt Federal Research Center (UdmFRC) of the Ural Branch of the Russian Academy of Sciences, candidate of technical sciences Dmitry Zhirov has developed a resource-saving mill. According to the press office of the UdmFRC Ural Branch of the Russian Academy of Sciences there are no analogues of such an invention in Russia.

The mill can be successfully used for grinding any solid-free-flowing materials of natural and technogenic formation that can be destroyed by impact - cuboid building crushed stone, building sand, enrichment and processing of mineral raw materials, metallurgical slags and other production wastes

Today, mills with one chamber are used for grinding solid-bulk materials; they are configured for one mode. Because of that, some particles are highly crushed, while others remain unmilled. This leads to waste of material and unnecessary energy consumption.

Multistage grinding technology provides for the withdrawal of the finished product after each grinding stage, which eliminates unnecessary overgrinding of the material, wear of working bodies and contamination of the final product with wear particles

Only the strongest particles reach the last stage of work with multistage grinding technology.

The new mill has no wear parts and it is compact for ease of use. The development can be used in agriculture (the energy consumption of the grinding process is reduced by one and a half to two times).
