Oct 10, 2016 · In long ball mills the grinding occurs only at the front and the rest of the balls in the drum only increases power consumption. Drum mills have one grinding chamber (short and long ball mills) and two or more grinding chambers (long and pipe ball mills). Singlechamber continuous mills are the main equipment at mining and processing plants.

Feb 16, 2015 · Grinding energy was approximately 50 per cent of the ball mill and the drying capabilities allowed direct processing of materials of up to 20 per cent moisture content. The main energy issue was the high power consumption of mill fans, with pressure drops of 100mbar not uncommon with high nozzle ring velocities (>70m/s) and internal mill ...

The mill product can either be finished size ready for processing, or an intermediate size ready for final grinding in a rod mill, ball mill or pebble mill. AG/SAG mills can accomplish the same size reduction work as two or three stages of crushing and screening, a rod mill, and some or all of the work of a ball mill.

Feb 08, 2021 · Abstract Ball drum mills (BDM) are one of the main types of coalgrinding equipment in Russia. A significant drawback of BDM is high power consumption (a significant part of the TPP's own needs). With a huge scale of production, reducing these costs even by a few percent gives a significant economic effect. The problem of minimizing the specific energy consumption for grinding and ...
