The hammer crusher‚ also called the hammer breaker‚ is used to crush all kinds of medium hard and brittle materials of little-abrasion‚ whose compressive strength is no more than 100MPa and moisture content less than 15%‚ such as coal‚ salt‚ chalk‚ gypsum‚ tile and limestone. It is also used to crush fiber structure‚ cracked wood of strong elasticity and toughness‚ paper‚ or the waste of cracked asbestos cement to recycle the asbestos fiber and so on. Moreover‚ the hammer crusher can not only be

it may form depressions. Intrusive rocks tend to be coarse grained‚ since the magma cools slowly and has sufficient time to form large crystals. Extrusive igneous rocks cool rapidly at the earth’s surface‚ producing fine grained or glassy rocks. Basalt is fine grained because it cools very rapidly‚ whereas granite is coarse grained because it has cooled slowly. Batholiths are underground masses of magma often forming dome-like chambers. Granitic magmas are usually viscous‚ so they tend to produce
