Then it is thrown against an angular rock bed and is struck by other rock being thrown by the rotor. With the swirling action of the material, it shapes the rock into a more cubical product with some fines generation. As a result of the designed crushing action, a high rotor R.P.M. is necessary, resulting in high horsepower requirements for fines yield. We all know that crushing rock with impact crushers give us cubical particle shape and high fracture percentages, but going further, the Canica impeller and anvil V.S.I. is the right tool for fines production and prepping material before ball mills. Because of the patented geometric design of the crushing chamber, less horse power is required due to slower R.P.M.'s of the impeller table.
Higher fines yield per horse power.
Due to a higher first pass production, the recirculation loads are lower. This allows for a high screening efficiency. One problem with impact crushing is the gradation will change. When the wear parts are new, there will be high fines production. As the wear parts are worn, the amount of fines decrease.
