Firstly we should focus on the hardness,select the suitable model curhsing equipment on basis of output size range and crushing priciples.When stone cursher is used for crushing limestone, we mainly propose the hammer crusher,sand screening machine philippineswhen engineers design the hammer crusher,many factors will be considered.On the secondly,we should pay attention to the abrasion of amterials,when we decide the suitable crusher,watch out the strong abrasion materials fall into stone crusher,which may prolongs service life of wearing parts.finally,gravel crushers to buyStrict control moisture containing,granularity,and make sure the evenly feeding of materials.
In general, the mineral processing equipment failure parts to repair the material can be saved, reducing the quantity of reserves processing and spare parts, thereby reducing the cost. The following for you to explain in detail. 1, repair parts require sufficient service life, its durability at least should maintain a repair interval, prevent and stop because of failure and accident. 2, mineral processing equipment parts repair to restore and maintain the technical requirements of the original, including the size, shape and position tolerances, surface quality, enough strength and rigidity etc.. 3, repair of mining machinery parts to consider the economic benefits, reduce the cost of repair in ensuring the premise requirement of first under item two. In comparison to repair, replacement cost and service life, if the relative repair cost is lower than the relatively new product cost, should consider the
