•  The quality of the product is very high, content of needle plate type is no more than 5%. A diabase in Huzhou, Zhejiang province once adopted Jaw Crusher-Impact Crusher. But content of needle plate type is more than 10%, resulting the bad sell of its product. After using VI Series Vertical Shaft Impact Crushers, the content of needle plate type in the product is reduced to 4.7%
　　•  The production improves 50% compared with utilizing Impact Crusher as the final processing of crushing.
　 　•  Because we utilize Impact Crusher as the secondary crusher, and Vertical Shaft Impact Crusher consumes little metal, the consumption of wear-parts reduced largely in the whole processing
