On the present domestic market, crusher equipment has great development in
mine, building materials, road construction, construction and other various
industries.People demand for sand aggregate is bound to generate growth.
In the domestic large-scale water conservancy project, the quality of sand
aggregate is more and more attention. The most early method to develop sand is
using hammer crusher.However, hammer crusher is only suitable for crushing in
brittle materials, hardness of material is not more than 100 million mpa.To
impact crusher, adopting the principle of efficient stone hit stone production,
material is repeated crushed by impact crusher, and then to new sand making machine whose power is half the impact crusher and output is more 50% than
impact crusher, it is the ideal system sand machine on the present market ,
It also gets the user's consistent high praise in China.zrf
