How to Use an Impact Crusher

Impact crusher machine crushes materials with impact force. The materials were drop into the high-speed rotating of impeller and are crushed with the materials spread in the forms of umbrella - shaped around the impeller under the force of centrifugal. Then the crashed materials are thrown to the impact plates on the rotor for further crush and followed with a third crash back to the blow bar again, forming a closed-circuit loop. This process will not ends until the materials are satisfies the size required and discharged from the lower part of the machine. By adjusting the gap between the rotor support and impact rack, he size and shape of the finished powder can be varied. The degrees of power will be controlled by the screening equipment.

Impact crashers are indeed widely used in wide variety of industries and play an essential part in those fields such as mining, transportation and construction.Here is some proper advices on how to use impact crasher”

1、The installation between impact crusher and the power unit should be tightly secured. It should be fixed on the basis of cement if the impact crasher works permanently while if it is mobile operated, the power unit should be installed on a frame made of angle iron and be make it sure that the pulley grooves between the generator(diesel engine or electric motor) and impact crushers are at the same rational plane.

2、When completing the installation, the fastening condition of fasteners should be carefully checked and fixed if it is not. In the meanwhile, checking whether the elasticity of belt is appropriate

3、Before starting, turn the rotor with your hands, check out if the tooth-jaw, hammer and rotor is in a flexible and reliable operation condition and see if there is collision within the shell, if the direction of rotation of the rotor is consistent with the direction indicated by the arrow, if the lubrication between the power and impact crusher goes well.

4、Do not replace the pulley, in case of explosion of the crushing chamber causing by excessive operating speed or impact crusher's efficiency resulting from a excessively slow speed.

5、Impact crusher should be idling 2~3min after starting, then feeding with no abnormal phenomenon .

6、Work to keep functioning of impact crusher, feeding should be uniform to avoid blocked stuffy, don't overload for a long time. If you notice vibration and noise or the temperature of the bearings and the body are too high and to phenomena such as spraying material, the crasher mush be immediately shut down, it can not restart unless troubleshooting.
