Dry Ball Mill

Dry type ball mill has no water in the production, which is of straight cylinder with wind conducting device, dust discharging pipe and dust collector.  We can design and manufacture other type of ball mill according to the customer's requirement, or by the customer's mineral sample, capacity and size dimension. By making ore grinding test and calculation, we can confirm the suitable model and type, and design the best working condition of the ball mill, making them that they have not only no functional shortage and also ensuring the capacity and size requirement.

Dry Ball Mill Introduction

Dry type ball mill has no water in the production, which is of straight cylinder with wind conducting device, dust discharging pipe and dust collector.  We can design and manufacture other type of Cement Ball Mill according to the customer's requirement, or by the customer's mineral sample, capacity and size dimension. By making ore grinding test and calculation, we can confirm the suitable model and type, and design the best working condition of the ball mill, making them that theyhave not only no functional shortage and also ensuring the capacity and size requirement .It is the key equipment for grinding after the crushing process, which is widely used in the manufacture industries, such as cement, silicate, new building material,refractory material, fertilizer,ferrous metal, nonferrous metal and glass ceramics and can be used for the dry and wet grinding for all kinds of ores and other grind-able materials.

 

Dry Ball Mill Working principle 

Ball milling 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.

 

Dry Ball Mill Structure 

Dry type ball mill is composed by feeding part, discharging part, turning part and driving part(reducer, small driving gear,electric motor and electric control). The quill shaft adopts cast steel part and the liner is detachable. The turning gearwheel adopts casting hobbing process and the drum is equipped with wear-resistant liner, which has good wear-resistance. The machine is withstable and reliable working condition.

Moreover, according to different materials and discharging methods, there are dry ball mills and wet ball mills for choice.
