Impact crusher is a new type of high efficient crushing device, which is characterized by small size, simple structure, big crush ratio (up to 40), low energy consumption, large capacity, particle size uniformity, and selective crushing role, is a very promising device.

Pay special attention to the situation in the operation process of impact crusher, so learn some emergency treatment about impact crusher is necessary.

1.         Bearing temperature too high

Solution: First of all, to check whether the lubricating grease reduce, the standard should be full of grease on bearing capacity of 50%; Cleaning bearings and replace lubricating grease in time; if the bearings wear seriously, please replace bearings

2.         Crushing cavity inside with abnormal severe knock

Solution: Immediately power off the crushers, parking and cleaning up the crushing chamber; Checks cannot be broken materials enter the crushing Chamber. Machines in operation will have a huge vibration, so check the fastening of scaleboard and the gap between the hammer and the scaleboard. Check the Wear-resistant lining Board are shedding; Replacement of broken pieces.

3.         Discharging particle size too large

Solution: Adjusting the gap of counterattack frame or replacing seriously worn scaleboard and board hammer; besides adjust the position of counterattack frame, making counterattack on both sides and frame lining to achieve relative gap to ensure the size of material.
