Dolomite powde
Dolomite powder is sorted, crushed, grinded to 325-1250 Mesh , in the friction material, its role is basically the same with the light calcium powder performance. after surface modification age to change the white surface alkaline powder, improve and rubber friction with properties of materials so as to greatly increase the reinforcing properties. Because of its mining easy, low cost, is widely used in friction as filler.
