DRY MILLS

These mills are used for dry milling of cement, building materials, etc. as well as coal of various ranks in the coal pulverization systems at heat power plants.
A new armouring lining never used in practice before and tumbling bodies in the form of the constant width tetrahedrons, which enable to reduce specific metal content, were employed in the mill design.
