Shaft mining or shaft sinking is excavating a vertical or near-vertical tunnel from the top down, where there is initially no access to the bottom.. Shallow shafts, typically sunk for civil engineering projects differ greatly in execution method from deep shafts, typically sunk for mining projects.When the top of the excavation is the ground surface, it is referred to as a shaft; when the top ...

Introduction. Vertical shaft impact crusher(vsi sand crusher) is widely used in crushing and reshaping of rock and artificial sand making. It is suitable for crushing of fragile materials below level 9 of Moh's hardness rather than viscous materials or stone materials containing much solid.
Impact 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.
