Increasing ball filling will increase the wear rate, and the grinding media shape of ball has a maximum wear rate. The wear characteristics of the lifter specimen are consisting of impact pit, indentation, plastic deformation and scratch.
However, it is now commonly agreed and accepted that the work done by any ball mill depends directly upon the power input; the maximum power input into any ball or rod mill depends upon weight of grinding charge, mill speed, and liner design. Working Principle & …
Larger ball and SAG mills, with higher installed power ratings relative to the mill diameter, offer higher efficiency and throughput, round-the-clock reliability and the opportunity to mine in remote areas. This makes low ore grades economical to grind.
Xinhai provides mineral processing technology, equipment manufacture and one-stop service for mineral processing plant, which solve many problems for mine investors. Xinhai equipment mainly include: ball mills, flotation, thickeners, and so on.
The $1.2 billion expansion, which saw throughput rise from 60,000 t/d to 120,000 t/d, involved the addition of two new thyssenkrupp-made ball mills, with ABB providing the gearless mill drives (GMD) technology. This came on top of the 33 mills the miner already had up and running as part of the existing 60,000 t/d plant at the operation.

As the rotation speed of the high-speed vibrating ball mill was not adjustable, the factory default setting of 1200 r/min was used. It is generally believed that the ball mill has good grinding efficiency when the interstitial filling fraction of the material is 0.6-1.2 [49, 50]. The parameter setting of the ball mill is shown in Table 1.
Grinding mills, including SAG (semi-autogenous grinding) mills and ball mills, consume approximately 60-70% of the total energy cost of the entire mining operation. The mills are installed with large motors, up to 20+MW, which impart the required energy to successfully process many tonnes per hour and grind the rock to a powder size suitable ...
