Application of Vertical Shaft Impact Crushers: Dafu Vertical Shaft Impact Crusher a high efficient rock crushing equipment with home and international leading level; the impact crusher is developed by introducing the crushing theory and technology from Barmag Company of America and combining the actual situation of sand making. The Vertical Shaft Impact Crushers is widely used for medium-sized and fine crushing and shaping in the following industries: minerals, quarry, abrasive, cement, refractory materials, alumina, quartz sand, emery, glass and so on. The final products of the vertical shaft impact crushers have a much better cubical particle shape when compared to compression machines such as cone crusher.The Vertical shaft impact crusher has been proved revolutionary in improving capacity and in reducing operating and wear costs. The Features of Vertical Shaft Impact Crushers: 1. The Vertical Shaft Impact Crushers features of simple structure, high crushing efficiency and low production cost. 2. it can fine crush and crude grind materials, and the crushed products are of cubic shape. 3. the influence from the water in materials to the machine is little. 4. it is suitable for crushing materials of medium, high and super hardness. 5. it works by stones hitting stones, so there is little wear for the machine and it can save energy and is of low grade and the fineness of the sand for construction after being washed can be up to the national standards, such as “sand for construction” and “cobble and broken stones for construction” features of fine stabilization, low noise. 6. because it crushes materials in the cavity, the dust pollution is little. 7. When used along with the rod mill and ball one, it can simplify the flowing process, lessen the energy consumption, improve the production efficiency and cut down the cost to a large degree.
