1. What is the potential for energy use reduction in pulp and paper mills? 2. How can this potential energy use reduction be achieved? Benchmarking provides a means to determine the potential for energy reduction. A benchmarking study is a comparison of the competitive situation among similar types of mills producing the same product [1].

The balls which could be of different diameter occupy 30 – 50 % of the mill volume and its size depends on the feed and mill size. The large balls tend to break down the coarse feed materials and the smaller balls help to form fine product by reducing void spaces between the balls. Ball mills grind material by impact and attrition. The degree ...

Reducing the instantaneous power demands is an effective approach to reduce energy consumption, which can be achieved by energy-oriented component design optimization . The optimized moving components with high transmission efficiency, such as the precise ball screws and gears, should be used in machine tools to reduce instantaneous power loss.

The starting point for ball mill media and solids charging generally starts as follows: 50% media charge. Assuming 26% void space between spherical balls (non-spherical, irregularly shaped and mixed-size media will increase or decrease the free space) 50% x 26% = 13% free space. Add to this another 10%-15% above the ball charge for total of 23% ...

2. More crushing and less grinding to reduce the feed size into mill. The larger feed size, the more work that the ball mill needs to do on the ore. To achieve the specified grinding fineness, the workload of ball mill will be increased inevitably, and then, the energy consumption and power consumption will be increased accordingly.
