This machine changes the intrinsic grinding machine structure. It's body and ground plank are an integral whole so when fixing. It can be lowered on a plane surface once only. This machine uses double tiered roller axletree with centripetal spherical surface as the support of the host axletree can reduce energy cost by 30%. The intrinsic gritle pattern

forcing evacaution is instead by overfall pattern controlling one. This

can improve the milling of the granule and the quantity dealt with is inc

reased by 15-20%.
