Compact impact crushers can process natural rock, concrete, and asphalt into aggregates for construction. However, certain materials (so-called uncrushables) cannot be crushed and can cause damages inside the crusher box and stop your production.
If you feed uncrushables in your compact impact crusher, anything can happen.
You can break a hammer on your impact crusher
You can bend your rotor shaft
You can damage conveyor belts
Increase wear
Being in control of your feed and material prep allow you to set uncrushables aside or avoid that uncrushables end up in your feed pile. Check out the blog post Small Rock Crusher Feeding Tips for Novice Operators. Here you can find more practical tips on how to operate a compact impact crusher.

RUBBLE MASTER compact impact crushers feature the RM Release System to reduce the risk of major damages by allowing the force to be absorbed and the uncrushable to pass.
Oversized concrete slabs and uncrushables can interrupt production. The RM Release System features a spring-loaded impact wall that absorbs some of the force and allows the room to let materials pass more easily. It can also be activated by the touch of a button on your radio remote control to let over-size concrete pieces fall into the action radius of the rotor.
When your hammers break, you need to change the set (the broken hammer and the opposite hammer) immediately to avoid further damages to the rotor. If you don't have spare hammers available quickly you lose production and money. The optional hammer bracket allows you to keep a spare set of hammers on your compact impact crusher to reduce your downtime and hassle to get the hammers to the jobsite.
