Feed material of reduction ratio of impact crusher: All operations in size reduction, both crushing and grinding are of course determined by the feed characteristics of the minerals (rock/ore) moving into the circuit. The key parameters we need are the “crushability or grindability”, also called work index and the “wear profile”, called abrasion index.
As seen above all size reduction operations are performed in stages. All mining equipment involved, crushers or grinding mills have different relation between feed and discharge sizes. This is called reduction ratio.
Liming Heavy Industry offers primary horizontal crushers (PF impact crusher series) and secondary horizontal impact crushers (PFW European Impact Crusher series) for the crushing of soft and medium hard materials. These horizontal impact crushers have a very high reduction ratio, which normally results in a three-stage crushing plant becoming a two-stage plant, using the Liming Heavy Industry PF series and PFW Series Europe impact crusher rang of crushers. The latest generation of impact compact horizontal impact crushers from Liming Heavy Industry have been specifically designed to ensure rugged reliable operation coupled with simple maintenance, interchangeable wear parts and fast part replacement.
Liming Heavy Industry horizontal impact crushers provide low capital cost solutions, optimum performance and good cubical shape, whilst ensuring the lowest operating cost per tone, for a wide range of materials and applications.
