This machine changes the original grinding machine structure. Its body and ground plank are an integral whole. So when fixing, it can be located on a plane surface only once. Use double tier roller axletree with centripetal spherical surgaxw as the support of the host axletree can reduce energy cost by 30%.The intrinsic grille pattern forcing evacuation is instead by overfall pattern controlling one. This can improve the milling of the granule and the capacity is increased by15-20%.
