Summary
The centrifugal impact grinders are meant for crush grinding of mine and non-mine materials.
Description
The design of the centrifugal impact grinders is based on the
major “air-cushioned” node developed by the Association allowing rotating
heavy loads at high speed and high degree of unbalance. This enabled to create
a spectrum of equipment ensuring supreme technical characteristics and highest
quality of the product manufactured using this equipment. In the centrifugal
grinders material is crushed due to its speeding-up in the rotating accelerator
and strokes against baffle elements due to existing centrifugal forces.

Technology type
Technical advantages and economic benefits
As compared to fine crushing due to shear stress in cone and jaw
grinders, crushing in centrifugal grinders as a result of strikes has explicit
advantages allowing:
- to obtain break-stone of predominantly cube-like shape;
- to reduce total expense for achieving final product due to high degree of
fine crushing.
Technology differentiation and uniqueness
Obtaining high-quality constructional materials.
Context in which technology was identified
The centrifugal impact grinders are successfully used by industrial enterprises of Russia, Belarus, Kazakhstan, Ukraine, Estonia, Uzbekistan, Vietnam.
