1. Quarry crusher wear parts (mainly liner) to replace the inconvenience, wasting a lot of manpower and time; 2. the third stage quarry crusher liner damage fast speed, affect the life of the whole device. Can be achieved by improving the way the third stage of crushing; 3. the face of a lack of ability to adapt to abnormal operating conditions, mainly for lack of iron is automatically released through the ability to work with severely restricted its continuous stability;
4. crusher grinding and screening systems is likely to cause even poor discharge device stuck faults, severely limits the processing capability of the device; 5. the degree of automation to be improved. For example, when there is superhard materials falling into the cavity, can not be found. Based on this, quarry crusher before the official market, the transformation of the letter to be appropriate, the subject of my research is to address these practical issues of the novel conical teeth roll crusher equipment modification.
Calculation Method of quarry crusher:
1. with a maximum particle size before crushing materials with a maximum particle size than the product after crushing calculate the maximum size i = Dmax / dmax where Dmax-- before crushing materials; maximum size after dmax-- broken material;
2. with quarry crusher feed opening and the effective width of the discharge opening width ratio of i = 0.85B / b. Where B --- crusher feed opening width; b --- Crusher & lt; discharge opening width; 0.85 crusher bite ensure the effective width of the material feed system. Value of the discharge opening width, take the largest coarse crusher discharge opening width; the quarry crusher discharge opening to take a minimum width;
3. with an average particle size calculation i = Dcp / dcp where the average diameter of the front Dcp- broken materials; mean diameter after dcp- broken material. This method is obtained crushing ratio, can be more truly reflect the extent of gravel crushing equipment.
