Description

Known siisaiymi ku € K1lsh. materials on two or more rotary hammer crushers with the subsequent transfer of material from one rotor to another.

The distinctive feature of the described method is that in order to increase the impact on the product ejected by the ro-toro is the primary. of crushing into the rotor of secondary D1) lining, and the current of this product is imparted by the beats of the secondary crushing rotor to a shock action during a meeting | aiG1avlsni city

In a two-rotor hammer crusher to implement this method, the secondary crushing rotor is installed at the same level as the rotor of the primary crushing with a radial clearance between the ends of the beaters And rotates at a greater peripheral speed.
