Incorporating a grizzly screen upstream of a crusher reduces wear and extends the crusher’s operating life. Grizzly screens feed material across the complete width of the crusher’s inlet, eliminating uneven wear of the crusher. It also separates out thru material, ensuring the crusher only processes the overs. This benefits the crusher in two ways. First it extends the crusher’s operating life by reducing the amount of material it processes. Secondly it allows for a smaller sized crusher to be used, saving on initial capital investment and operating costs.
