Dec 13, 2011 ball mills are always preferred to be operated at full capacity because the power consumption of this type of mill is very high at lower loads when compared with other types. ball mills can be designed for a very high capacity like 75 tons per hour output for a specific coal.
Ground product. 1. mahlk rper. 2. adjustable discharge slots. activate the markers for further information. working principle. fed into the mill through one or both bearing trunnions, the material is ground by impact and friction from the balls. the ground product is discharged from the mill through discharge slots provided in the mill tube ball mill.
May 22, 2019 the ball mill consists of a metal cylinder and a ball. the working principle is that when the cylinder is rotated, the grinding body ball and the object to be polished material installed in the cylinder are rotated by the cylinder under the action of friction and centrifugal force.Jun 23, 2020 estimates of the increases in power draw possible with grate discharge ball mills range from 10 to 20, according to mill size and other operating parameters. the figures from pilot tests and some operating sites are even higher, up to 25 more power draw.Operating a ball mill is quite simple as it lacks any moving mechanical parts within the mill. the system is quite versatile and is designed to accommodate variation in mill feed quantity and quality. on the other hand, the vertical roller mills vrm is quite a complicated and sophisticated equipment with hydraulics that controls the rollers.
