10” gas or electric motor powered impact mill is perfect for sampling or small production in mining applications. 1.5” inlet port, 1.5” outlet port. Perfect size for packing in to remote areas.
Patent pending design is the latest and greatest in pulverizer technology. This design is far superior to old design in the following ways: A. Far far less likely to have the screen plug up B. Screen life is at least 10 times that of competitors C. Constant production rate means a more consistent product with very little kickback through the inlet port. When crushing quartz or similar gold producing ore, crusher produces 90% passing a 20 screen on first pass which is the perfect consistency for gold liberation. This unit is durable enough to be used for small production in the beginning stages of proving up a mine.
Typically a 1” diameter rock passes through the crusher almost instantaneously, or usually in under a second. It is best to add water as rock is added to get the best results, and to have a dustless production, having ore sitting in water as it is scooped in is adequate. Machine may also be run dry as well. Pitted pipe used to have the best crush surface.
Gas engine and legs not included, but legs are easily made from 1/2” electrical conduit available at most hardware stores. These fit and lock into the leg mounts on the crusher. Any gas engine having a standard 2.5” square bolt pattern will bolt right up such as a Predator 79 cc or 212 cc from harbor freight. A 5/8” arbor coupler included, which will fit the 79 cc Predator engine, or many electric motors. A 3/4” arbor coupler necessary for the 212 cc Predator.
