Enter the maximum number of parallel crusher area population of premises crushed material during crusher operation began, after a sharp decline. Therefore, parallel zone strongly wear and crusher operation after several days, gradually changing the parallel region.

 

With the wear and crushing chamber liner contour changes, the crushed material distributed more evenly along the crushing chamber height. In the liner wear limit range is subject to change overall size of the crushing chamber, especially the latter no long parallel zone, the entire cavity shape completely lost original contour.

 

In this case feed opening size is reduced approximately 1.4 to 1.7 times the maximum amount of material feed port handled. Since there is no parallel region makes the product quality deteriorates, crusher production also declined. Since the liner wear uneven crushing chamber crushing chamber lose their original shape, resulting in low life liner and crushers technical and economic indicators declined.
