Operation and maintenance of the ball mill Project Background. After installation, the ball mill of mine equipment must pass the test of no-load and full-load before it is allowed to be put into formal use. There are usually two ways to judge whether the ball mill is working properly.
There are usually two ways to judge whether the ball mill is working properly. The first method is to check the material out of grinding fineness, if it meets the requirements, and beat is not big, it proves that the ball mill operation is normal, it is appropriate to add, the particle size of the material, water is very good, steel rod gradation is also appropriate.
How to Identify Whether Bearing Ball Mill is Failure or Not. Bearing is a main vulnerable part of ball mill. During the operation of ball mill, the bearing can appear some faults due to stress, assembly or other reasons. In order to reduce the impact on production, we need to judge timely whether the failure occurred ball bearings.
The solution is that you can judge the ball lining by the sound of the machine then find the loose bolts and tighten them. Chat Online common ball mill problemsbbatouchofrome . The Common Faults and Solutions of Ball Mill 3rd . 11 the ball mill cannot start or the motor overload when starting.

Ball mill operating characteristics. The rotation speed of the ball mill should not be too fast. If the rotation speed is high, due to the centrifugal force, the material and the steel ball will no longer detach from the wall of the cylinder, or even follow the wall of the cylinder.
Ball mills tumble iron or steel balls with the ore. The balls are initially 510 cm diameter but gradually wear away as grinding of the ore proceeds. The feed to ball mills dry basis is typically 75 vol.- ore and 25 steel. The ball mill is operated in closed circuit with a particle-size measurement device and size-control cyclones.

In previous studies, the analysis of ball mill operating parameters and their effects on breakage phenomena has been limited to homogeneous materials. Though these studies have proven to be an asset in predictions of product size distributions and mill scaleup, they have not addressed the primary role of grinding, i.e. liberation. I

Grinding cement in ball mills. The principle of the ball mill operation is simple it consists of a rotating drum and grinding media cylinders, balls etc. The material is placed into the drum which starts rotating. The grinding media and the substance both come in circular motion and at a certain point drop from the walls the bottom of the drum.
Traditional methods, the ball mill during the processing of materials usually can play two effects, one is broken effect, one is the grinding effect. General sense, breaking effect can be broken using other ancillary equipment to complete.The ground level of the direct effect of the impact of factors can be attributed to the control of ball speed.
