How to prolong the service life of sand making machine?
The main crushing form of artificial sand production machine is crushing. After accelerating the rocks, under the impact of the throwing head, some of them collide with the crushing chamber, some of them collide with the rocks. The wear of the main throwing head is very serious under the impact of the rocks for a long time. After a period of time, it must be replaced.
Otherwise, it will not only affect the crushing effect, but also affect the rotor body. The abrasion of rotor-body will affect its dynamic balance and easily lead to spindle fractures. It takes about some money to replace the throwing head of a sand production equipment, which results in a great waste. The wear of main throwing head is mainly caused by impact wear after impact. Each group of throwing head has nine components, and the middle three wear most seriously. In order not to affect the dynamic balance of the rotor, they should be totally replaced, which results in great waste. Therefore, adjusting the load on the main throwing head can prolong the service life of throwing head.
Rotor speed is an important factor affecting the crushing quality, efficiency and service life of sand making machine, but the crushing effect is not always improved with the increase of speed. High speed will also aggravate the wear of the main throwing head, even seriously affecting the service life of artificial sand production equipment. The experimental data shows that the force of the main throwing head is balanced at 1400-1500r/min and 1600-1750r/min, and the rotors can run smoothly, thus prolonging their service life.
