rock will overload the crusher and can cause the bowl or cone to float. "With float, the crusher will lose the closed-side setting (CSS) and more oversize rock will pass through and increase the amount of recirculating material," he says. "Such events can also increase fatigue and can damage the crusher or cause a catastrophic failure."
When an operator does not receive adequate training, oversized material could enter the crusher and cause damage or the crusher could malfunction due to faulty management. Every operator must be thoroughly trained on feeding the machine and the specific type of crusher they are working with. This makes for a safer and more …
