Each mill measures about 12m in diameter and has an internal volume of 1,220 cubic metres. As the AG mill turns, the ore crushes against itself and breaks apart. From the AG mills, the ore travels to the primary magnetic separators where the iron is drawn away from the waste material before it's screened and fed into the ball mills.

History. Tin mining in Perak around 1910. Tin mining is one of the earliest type of mining operated in Malaysia, starting in the 1820s in Perak and in 1824 in Selangor. [1] The development of mining industries in Malaysia attracted many Chinese immigrants who came to the state in 18th and 19th centuries to work and develop the mine fields. [2]

Ball Mills. The ore from the crushing section is delivered to the fine ore bin placed at the head of the grinding section, from which it is fed, together with water, to one or more grinding units consisting of a ball mill or rod mill in circuit with a classifier. One such unit with a conical ball mill is shown in Fig. 9.

Ball mills tumble iron or steel balls with the ore. The balls are initially 510 cm diameter but gradually wear away as grinding of the ore proceeds. The feed to ball mills (dry basis) is typically 75 vol.% ore and 25% steel. The ball mill is operated in closed circuit with a particlesize measurement device and sizecontrol cyclones.

Crushed ore is fed to the ball mill through the inlet; a scoop (small screw conveyor) ensures the feed is constant. For both wet and dry ball mills, the ball mill is charged to approximately 33% with balls (range 3045%). Pulp (crushed ore and water) fills another 15% of the drum's volume so that the total volume of the drum is 50% charged.

How a Ball Mill Works. Ball mills work by using balls to grind materials. Materials such as iron ore, pain and ceramics are added to the ball mill. Next, the ball mill is activated so that it rotates — either on its vertical or horizontal axis. As the ball bill rotates, the balls bounce around while striking the enclosed material. The force ...
