From feed to the discharge end, shell mill liners are beneficial for optimizing the performance increasing the lifespan of other replacement wear parts. It favors the lifting action of the balls. The dead zone around the ball charge is minimized. Shell liners reduce the wear rate in liners and balls, which in turn enhance their lifespan.

The disclosure is directed to a liner assembly for an autogenous ore grinding machine. The machine includes a large cylindrical drum which is rotated about a horizontal axis to comminute the ore. The liner assembly covers the inner cylindrical surface of the drum and consists of a plurality of longitudinal segments which are removably bolted to the drum.

After removing the nut, the moil is inserted into the bolt end. Without the need to remove recessed or seal washers the bolt can be driven out of the liner and completely clear of the mill shell in one movement. Recent trials at a large copper concentrator have shown that bolt removal time was halved by using Easy-Out Bolts.

Ball mill is a piece of important grinding equipment, which is widely used in mineral processing, building materials, and the chemical industry. It can be used for dry or wet grinding of various ores and grindable materials. However, the noise generated by ball mills in the production process is extremely loud and can easily damage the health of workers who …

The main roles of liners are to protect the mill shell and promote effective ball motion for grinding. For this reason the liner profile is carefully selected to ensure that the productivity is maximized and due liner replacement is made when this objective is no longer met. These issues have been extensively studied on shell liners as mill relining is a significant …

RME's Liner Bolt Removal Tools (LRTs), the THUNDERBOLT range, are specifically designed for assisting with relining the various sizes and types of grinding mills. In the 21st Century, no grinding mill reline is competitive without access to RME's THUNDERBOLT Recoilless Hammer technology for driving liner bolts and liners from mill shell engagement.

The massive 1500 Joule strike energy from the LRT120 ...

1. Liners protect the outer shell of the mill from wear - liners are renewable. 2. Lifters prevent slipping between the medium and slurry charge in the mill and the mill shell. Slippage will consume energy wastefully but more importantly it will reduce the ab ility of the mill shell to transmit energy to the tumbling charge.
