Grate Discharge Ball Mills: In this type of mill, the ground materials are discharged through the grate plate, which prevents the grinding media from exiting the mill. Grate discharge mills are used for coarse grinding. Peripheral Discharge Ball Mills: These mills have peripheral slots or grates around the discharge section, allowing the ground ...
The working principle of the semi-autogenous mill is basically the same as the ball mill. But it mainly uses the materials themselves inside the cylinder as the grinding media. For improving the processing capacity, a small number of steel balls or rods are added to the grinding chamber to assist in grinding.

Figure 3: Cross-sectional view of the laboratory mill shell lifters . The discharge end of the mill was fixed with a grate made of 3 mm thick clear acrylic sheet. A rotating discharge funnel was attached to the flange of the mill and passed into a fixed collection chute, from which the mill discharge was collected. A flexible sampler
The ball mill girth gear is connected to the reducer, which converts the rotational motion of the motor into the rotational motion of the ball mill. When the girth gear rotates, it drives the ball mill cylinder to rotate, causing the materials and grinding media in the cylinder to have strong impact, collision, and friction with each other ...
