2.More crushing, less grinding, reduce the particle size into the mill. If the grinding particle size is large, the work that the mill needs to do on the ore will be more significant. To reach the required grinding fineness, the workload of the ball mill will increase, and subsequently, energy consumption and electricity consumption will also ...
A ball mill also known as pebble mill or tumbling mill is a milling machine that consists of a hallow cylinder containing balls; mounted on a metallic frame such that it can be rotated along its longitudinal axis. 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.
Here are ten ways to improve the grinding efficiency of ball mill. 1. Change the original grindability. The complexity of grindability is determined by ore hardness, toughness, dissociation and structural defects. Small grindability, the ore is easier to grind, the wear of lining plate and steel ball is lower, and the energy consumption is also ...

Here are the 10 ways for your to improve the ball mill performance: Step#1. Change the original grindability. Step#2. More crushing and less grinding to reduce the feed size into mill. Step#3. Reasonable filling rate of steel ball. Step#4. Reasonable size and proportion of steel ball.
The classification efficiency can be improved by adopting two-stage classification or improving classification equipment. 9. Appropriately increase the graded sand return ratio. The sand return ratio is the ratio of the sand return amount of the ball mill to the raw ore feeding amount, and its size directly affects the productivity of ball mill.
The speed of ball mill directly affects the motion state of steel balls and ores in the ball mill. When the speed is too slow, the steel balls and ore will slide down without rising high, and the crushing effect will be small; when the speed is too fast, the grinding medium will attach to the inner wall of the ball mill and rotate.

In terms of this concept, the energy efficiency of the tumbling mill is as low as 1%, or less. For example, Lowrison (1974) reported that for a ball mill, the theoretical energy for size reduction (the free energy of the new surface produced during grinding) is 0.6% of the total energy supplied to the mill setup.
