overflow or grate mill --CHINA YUFENG

 Ball mill is an efficient tool for grinding many materials into fine powder.  There are two ways of grinding: the dry process and the wet process. It can be divided into tabular type and flowing type according to different forms of discharging material.

 

  

The ball mill is a key equipment for regrinding. It is widely used for the cement, the silicate product, new type building material, fire-proof material, chemical fertilizer, black and non-ferrous metal, glass, ceramics and etc. 

 

  

The ball mill is a skeleton pattern ball mill with horizontal cylindrical turning gear, drive by outer gear and two hoppers. The material goes to the first hopper after the spiraling by the quill shaft from the feeding equipment. The hopper has ladder sheathing or corrugated sheathing with steel balls inside, which will fall under the effect of centrifugal force by barrel turning to ram hard and grind material. After the kibbling in the first hopper, by monolayer partition panel, the material will enter the second hopper, which has plane scale board with steel ball inside to grind material. The powder material will be discharged from the grid plate to finish the grinding.

 

 

1.Double-row self-aligning spherical roller bearing replaces babbit-lined bearing. Friction resistance is greatly lowered down, easy to start and 20-30% of energy is saved.

2.Grooved and ringed liner increases contacting surface between balls and ores, improving milling effect and saving energy through its lifting effect to the materials.
