Handle and support frame 3.
Material is gravity fed into the hopper and drops into the center of a high-speed tube.
The centrifugal force throws the rock into a hardened steel impact wall at speeds in excess of 400 miles per hour. If any uncrushable particles are fed into the unit it will automatically pass them without damage or hesitation. All material after crushing then passes automatically into a five-gallon bucket sealed chamber providing a low dust environment. Ideal for crushing all types of quartz, schist, limestone, etc. This new machine is also ideal for crushing black sand concentrates to release any encapsulated micron gold for further processing.
