Percussion machine for crushing and/or grinding mineral materials has frame dimensions selected to allow installation of different wear plates and beaters

摘要

The percussion machine consists of a frame with a fixed base (1) supporting a fixed central section (2), a rear tilting section (3) and a front tilting barrier (4) with inner walls covered with armour plates (7), a rotor (8) with a horizontal axle (9), impact screens (14) and beaters. It differs in that the dimensions of the frame are selected to allow the installation of wear components that suit mineral materials with different degrees of abrasion, or impact plates and beaters of different sizes. The machine is also equipped with a vibrating distributor (18) to provide an even feed to the whole length of the rotor.
