In recent years, with the development needs of the construction industry, the mining industry is getting more and more prosperous, and also promotes the development of mining machinery. In mining, the grinding ore is usually carried out in the abrasive machine.
There are more types of mills, but the ball mill and rod mill is generally used in metal mines.
The gravel mill and self-grinding machine have been apparently applied in China. The ball mill is a swivel garden barrel with a hollow shaft at both ends, with a considerable number of steel bars and steel balls.
When ore and water are given to the garden cylinder from the hollow axis of one end, discharge from the hollow axis of the other end.
When the ball mill is rotated in accordance with the specified speed, the steel ball and the steel rod together with ore, with the centrifugal force and friction, and then leave the cylinder to a certain height, then detach from the walls to do and slide.
They then rose to the same height as the cylinder, and then fall, periodically, so that the ore is affected and grinded.
Ground ore and water form a slurry (wet milling), discharged from the hollow shaft of the mineral end to complete the milling operation.
