FIELD: process engineering.
SUBSTANCE: invention relates to material grinding and can be used in various industrial branches in production of high-quality cements, flour and finely-dispersed multi-component mixes of various materials and powders. Proposed device comprises hollow closed housing with axial inlet hole and cylindrical grinding chamber. Said chamber accommodates horizontal rotary disks arranged coaxially to counter rotate and furnished with inner annular belts provided with circular lines of opposed grinding elements. Every circular line has alternating grinding elements of trapezoidal shape and flat lengthwise strips with their surfaces making pockets for ground materials together with rotary disk circular belt. Flat lengthwise strips have through radial holes.
EFFECT: higher quality and efficiency.
