VSI Vertical Shaft Impact Crusher (namely, sand making machine) is our patent products developed for abrasive materials, metallurgy, building materials, refractory materials, cements, pottery and porcelain and chemical industries. It is the up-to-date equipments in 1990s on medium and fine crushing, which applies to various materials, such as: Corundum, Carborundum, all kinds of smelting ores, building gravel, machine-made sand, cement material, and all of rigid and fragile material.
Working principle:
Materials are added in the cavity from the top of machine evenly; the materials are divided into central flow and scattered flow by sort set and overflow adjustment valve (fill valve); fill valve may adjust runoff ratio between central flow and scattered flow; the materials entered into turntable through central feed gate are thrown out from three even interval channels and impinge against the scattered flow at the speed of 50-80m/s when the materials are in the revolving rapidly turntable; when crushing, the materials crack along the natural plane of weakness and crush and then break on the vortex layer of crushing cavity together; form raising vortex through repeat striking; crush with jet flow again; mill-crush-mill-……until lose its energy and fall from gravel chamber.
Features:
1.Novel and special structure; steadily and credible operation.
2.Energy-saving, high-efficient capacity, great reduction ratio.
3.Compact structure; convenient operation, installation and maintenance.
4.Much better cubical particle shape.
5.During production, materials can form protection bottom layer and protect the machine from wear and tear.
6.Little quantity of wearing parts; compact structure; light weight; be made of special rigid materials; long service life; easy to replace.
7.For best mode of production we may adjust the related structure and parameter according to customer’s request.
