2.High bulk density
The high density, high hardness and the high grinding characters save the grinding time, enlarge the smashing room. So it can improve the grinding efficiency.
Product Features:
As a catalyst reactor, coverage tower packing materials and support, the major role is to increase the
distribution of gas or liquid, support and protect the intensity of low strength activity catalyst.
