I had to modify my design a little on the belt system of the impact mill rock crusher. The single "A" type belt on inexpensive off-shore aluminum belts, could not handle the power I was trying push through. The heat build-up in the belts destroyed the small pulley. So I have now redesigned the belt system to be double "B" belts on cast iron pulleys. Now the engine can easily get it's power through to the rock crusher.
