This machine is mainly composed of components such as the casing, rotor, striking iron, and grate. The casing is divided into upper and lower parts, which are cut from steel plates and welded together; The remaining parts are bolted together as a whole. The interior of the casing is lined with high manganese steel plates, which are easy to replace after wear and tear; The spindle is equipped with a regularly distributed array of hammer heads, which together with the turntable and hammer shaft form a rotor. This machine drives the main shaft through a motor and a V-belt, causing the rotor to rotate. The hammer head is stretched outwards by the centrifugal force generated during rotation. Large pieces of material enter the crushing chamber from the feeding port and are then broken by the high-speed moving hammer head. The qualified crushed material is discharged through the slotted grate at the bottom. To avoid blockage, the moisture content of the crushed material generally does not exceed 10% -15%.
