The Alpine Ball Mill for the dry comminution of hard materials, especially for the ultrafine range < 10 µm in circuit with an Alpine ultrafine classifier.
Ball mills are giant drums that are filled to between 30 and 40% of their volume with freely moving grinding media, in this case balls. The diameter of the balls is between one and several centimetres to suit the application with smaller balls for fine milling and larger ones for coarser milling tasks.
The drive sets the milling drum into slow rotation and the bed of milling media is thus activated, i.e. the balls are lifted and then impact back against the bed.
A mill of this size equipped with steel grinding media converts approx. 50 kW per m³ of feedstock. The feed product is fed continuously through the trunnion and is discharged through slots on the opposite side. The discharge rate can be adjusted as a function of the number of open slots. The ground product is transported – often pneumatically – and is charged to a downstream classifier. The coarse material is returned to the mill together with the feed product.
Load cell technology results in precision product level control
A high consistency of the product quality demands exact measurement of the amount of product in the mill and because of this, an optional accessory offered for our ball mills is the load cell system which permits precision control of the product level. The complete ball mill is located on a steel or concrete frame designed to rest on a defined number of load cells. These load cells are integrated into a control unit and determine the total weight of mill, grinding media and product. The addition of virgin feed can be controlled with such precision that the mill always operates at optimum load. This means reliable prevention of no-load operation or overfilling, and mill operation is exceedingly cost-effective.
