Problem 1: When the ball mill is running, there is a very frequent hitting sound and the sound is also very large. Solution 1: It should be that some of the lining bolts are not tightly screwed. The solution is that you can judge the ball lining by the sound of the machine, then find the loose bolts and tighten them.

Knowing the causes and solutions for bearing issues
If the bearing malfunctions and fails, it is best to identify the cause of the problem. By doing so, you conduct proper techniques and utilize necessary adjustments to address the issue. In fact, it is easier to determine the underlying problem when you examine the failure mode. However, it is quite complicated to go through this procedure since a single failure mode tends to lead to another.
12 Reasons Why Bearings Fail Reliable Plant
By becoming aware of the different problems that can cause a bearing failure and the signs to look for, you have already taken a big step toward limiting machine failures. Of course, you don’t have to wait for the symptoms of a bearing failure to take action. Regular preventive measures can keep your bearings at peak performance for as long as possible, saving your business time and money

Ball Mill: Operating principles, components, Uses
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. The large balls tend to break down the coarse

Ball mills are filled up to 40% with steel balls (with 30–80 mm diameter), which effectively grind the ore. The material that is to be ground fills the voids between the balls. The tumbling balls capture the particles in ball/ball or ball/liner events and load them to the point of fracture. When hard pebbles rather than steel balls are used for the grinding media, the mills are known as

Ball mill Wikipedia
A ball mill is a type of grinder used to grind or blend materials for use in mineral dressing processes, paints,pyrotechnics, ceramics, and selective laser sintering. It works on the principle of impact and attrition: size reduction is done by impact as the balls drop from near the top of the shell. A ball mill consists of a hollow cylindrical shell rotating about its axis. The axis of the
