الحصول على السعرCrushing is accomplished by compression of the ore against a rigid surface or by impact against a surface in a rigidly constrained motion path. Crushing is usually a dry process and carried out on ROM ore in succession of two or three stages, namely, by (1) primary, (2) secondary, and (3) tertiary crushers.
الحصول على السعرCrushing is normally carried out on "runofmine" ore, while grinding (normally carried out after crushing) may be conducted on dry or slurried material. In comminution, the size reduction of particles is done by three types of forces: compression, impact and attrition. Compression and impact forces are extensively used in crushing operations while attrition is the dominant force in grinding ...

الحصول على السعرImpact crusher. Impact crushers involve the use of impact rather than pressure to crush material. The material is contained within a cage, with openings on the bottom, end, or side of the desired size to allow pulverized material to escape. There are two types of impact crushers: horizontal shaft impactor and vertical shaft impactor.
الحصول على السعر· Blasted ore is further reduced in size by primary crushers, semiautogenous (SAG) and autogenous (AG) mills. SAG mills have special requirements on feed size distribution, which is influenced by the size distribution of the blasted rock (Esen 2013).The 80% passing size, x 80, is regularly used to evaluate the energy draw in size reduction (Workman and Eloranta 2003).
