The vertical - shaft crusher, also known as the vertical - shaft sand - making machine, is composed of transmission devices, bearings, upper machine covers, lining plates, hammers, hammer discs, main shafts, belts, feed inlets, discharge outlets, supports, motors, maintenance doors, cylinders, upper covers, bases and other parts. Its internal structure is simple and reasonable, and the operation cost is low. It utilizes the stone - on - stone principle and has little wear.
The working principle of the vertical - shaft crusher: Materials are fed in from the upper opening and fall into the crushing cavity. They are hit by the high - speed rotating plate hammers and are quickly thrown towards the impact plate. After impact, they are bounced back to the hammer plates and are hit again. At the same time, the hammers drive the materials to flow, generating a large grinding effect among them, further crushing the materials until they reach the required particle size.
