This study investigated ultrafine coal grinding performance of four low to moderatecost grinding media in a laboratory stirred mill. Kinetic grinding tests showed that silica beads generated the finest product size with a P 80 of μm from a feed size of μm while having a specific energy (SE) input of 309 kWh/ton. Nonetheless, the least energy consumption of 109 kWh/ton was ...

Ballmills are used widely for secondary grinding. Loveday (2010) reported on laboratory tests in which small pebbles (725 mm) were used in various proportions with balls. The optimum proportion of pebbles, by volume, was found to be about 25%. Substantial savings in power and ball consumption were achieved, with no loss in grinding capacity.

Vertical roller mills are a newer type of coal grinding mill and are characterized by their higher grinding efficiency, reduced maintenance requirements, and higher drying capacity. They use a rotating table to crush and grind the coal material, and a series of rollers to compress and squeeze the coal particles, producing a fine coal powder.

The coarse copper's ore size reduces due to the interactions between copper ore and steel balls during the ball mill's rotation. This study used two grinding media: a low chromium cast ball with a diameter of 80 mm and a high chromium cast ball with a diameter of 50 mm, tons of each were added into the ball mill daily.

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 ...
