The content of silver in the ore is low, in order to extract silver and need the ore crushing and grinding and the processing methods of pre enrichment or from ore in the silver separated. Silver dressing used in more re-election and flotation, gravity method plays very important role in the production of silver sand, the flotation method is rock silver mines hole mining is widely used processing methods. 

When the cone is broken, the motor drives the eccentric sleeve to rotate through the triangle belt, the driving shaft and the driving gear, and the moving cone moves in the eccentric sleeve to make the moving cone and the fixed cone move closer to the time. Material in the crushing cavity continue to be squeezed, impact and crushing, crushing of the material from the lower part of the discharge
