Ball Mill

1. Summary

Ball Mill has been primarily used for fine grinding. Ball Mill is key equipment, which pulverizes the material after crushed. Ball Mill is widely used in powder-making production line including cement, silicate, new-type building material, refractory material, fertilizer, ore dressing of ferrous metal and non-ferrous metal, glass ceramics, etc.

Highly reliable, easy operation and maintenance. Wear-resistant and durable. Grind to any level of fineness. Optional Capacity and model, these advantages brings our ball mill work efficient and energy saving.

Grate type and overflow type option, we adopt the bearing support instead of the sliding bearing support for highly standard powerful in function and operation, efficient in working period, time and energy saving. We-Shanghai Minggong Heavy equipment CO.,LTD is leading the profession and outstanding trend in the arena.

According to different materials and discharging methods, there are dry ball mills and wet ball mills options. our company owns the leading technology and rich practical experience and could offer the prompt reply and good service on the basis of the profession and responsible.

2. General working principle:
This ball mill is a skeleton pattern ball mill with horizontal cylindrical turning gear and driven 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.

Dry or wet ball mill will be optional according to material and ore-discharging mode.

3.Wet Ball Mill’s Working Principle
This machine is a horizontal drum-like rotary unit, its outside is driven along the gear, inside the drum is medium (steel ball),material is fed through the feeding end of the drum, by following the rotation of the drum, the medium falls down after being lifted to a certain height by the centrifugal force from drum movement, heavily bang on the material due to irregular slide and rolling. Grinding thus comes into being among the medium, material and drum, so as to grind the material. The material is continuously fed, dynamic granularity level difference is thus occurred between the feeding and discharging ends, fine material flows out of the drum slowly and gradually.

4. Ball Mill Features:

1) Ball mill is the key tool for grinding all kinds of mines or materials into fine powder or for selecting the mine
2) Ball mill is widely used in building material, and chemical industry.
3) Grinding Method could be devided into the dry way and the wet way.
4) Ball mill has two types, tabular type and flowing type according to different expelling mine
5) In the barrel rotates, the material can be crushed between the individual pieces of grinding media that mix and crush the product into fine powder
