Operation Principle of Wet Long-Cylinder Ball Mill -
Then I will introduce operation principle of wet long-cylinder ball mill, make the wet long-cylinder ball mill of Xinhai Mining Group as an example. Just like the picture, the aspect ratio is much larger than the conventional ball mill, the inside of the cylinder is divided into two to four different lengths and functional positions.

The operating principle of the ball mill - Primo Pizza
The disadvantages of ball mills include their considerable metal consumption and deterioration grinding media, as well as a lot of noise. Most of the energy useless lost during ball mill operation, leading to low it efficiency. But even a significant specific energy consumption for grinding material compensates beneficial effect by using mill.

Analysis of ball mill grinding operation using mill
2014-3-1 Variation of S ** and F ** with mill speed for wet grinding (60% solids by weight) of limestone in a 25.4 cm diameter ball mill used by Kim for the medium fine size distribution range. For the fine size distribution regime, the trend of variation for the two F ** values was observed to be similar to that observed in case of the coarse and ...

Ball Mill Operation. Ball mills ride on steel tires or supported on both ends by trunnions. Girth gears bolted to the shell drive the mill through a pinion shaft from a prime mover drive. The prime movers are usually synchronized motors. During rotation, a portion of the charge is lifted along the inside perimeter.
