Tube mill 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 rol ler 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%. Use: This machine can be used in concret, fir-proof material, chemical industry, nonferrous metal and black Metal, other departments, to smash all kinds of ores and materialsl.
