Grate discharge ball mill


Grate discharge ball mill install a grid board at the discharging hole,the grid board consist of many piece of the orifice plate, its grate hole width is 7 mm-20 mm, ore through the grate hole into the space between the grid plate and end frames,then the material will move up by the heave board, material slip down along the heave board, the powder material will be discharged .

 

Grate discharge ball mill Description :

Grate discharge  ball mill install a grid board at the discharging hole,the grid board consist of many piece of the orifice plate, its grate hole width is 7 mm-20 mm, ore through the grate hole into the space between the grid plate and end frames,then the material will move up by the heave board, material slip down along the heave board,  the powder material will be discharged .

This  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.

Grate discharge ball mill Application:

Grate discharge  ball mill used for grinding all kinds of ores and other materials, and is widely used in beneficiation, construction and chemical industry,etc.

Grate discharge ball mill Features :

1. The ball mill drive of the rolling bearing replace sliding bearing, friction is reduced greatly, starting easily, energy saving significant;

2. It's  discharge port adopt  the cone design, such increased volume, and forced the cone ball classification,more near the exit, the smaller the steel ball diameter, increased the role of the grinding repeatedly, and further improve the degree of fine materials;

3. It uses the groove type ring lining board, increased the ore contact surface, strengthening the abrasive, reduce the power;

4. It adopt the overall frame, facilitate the construction and installation of equipment
