Hammer crusher, the ideal product for producing artificial sand, is widely used for crushing materials such as coal, cement, gypsum, alum, brick, tile, limestone. The compressive strength of the material should not be more than 300 MP a and the humidity is less than 15 %. Which rotor from the spindle, disk, pin and hammer. The motor drives the rotor in the high-speed rotation of the crushing cavity. Material from the upper inlet goes into the rock crusher and is grinded and crushed by blow, impact and shearing of the high speed movement of the hammer.

Bearing overheated is filling the proper amount of grease, the bearing greases should fill 50% of their space volume. Cleaning bearings, replace the grease and then change the bearings. Sieve gap is clogged, feeding unevenness causes reduced production. And then to stop and clean the blockage of the sieve gap, you should adjust the feed mechanism. If the pin is loose or the elastic ring is wear. Then park and tighten the pivot nut to replace the elastic ring. If there is sound inside the machine percussion, stop the machine and then clean up the crushing chamber. Fill gap between the check lining hammer and screen bars, you can replace broken parts.

Replacement of hammer or cone wear static balance rotor is undesirable. The rotor breaks or if there is imbalance bending or break on the triangular disk , in this case, new hammerhead need to be selected according to weight so that the total weight is relatively equal to the hammer shaft . The static balance will meet the requirements. The hammer and pin should be repaired. Anchor bolts at the same time should be fastened.
