8.3.2.2 Ball mills. The ball mill is a tumbling mill that uses steel balls as the grinding media. The length of the cylindrical shell is usually 1–1.5 times the shell diameter (Figure 8.11 ). The feed can be dry, with less than 3% moisture to minimize ball …
The feed of the ball mill contains grinding balls. In order to effectively reduce the direct impact of materials on the ball mill feed bushing and improve the service life of the ball mill feed bushing, the feeding point of the groove in the feeding part of the ball mill must be as close to the side of the mill barrel as possible.
Practically all ball mills have a trunnion lifting hydraulic system which includes an hydraulic lift pump of any suitable type with a line connected to' the bottom of the bearing. Prior to starting, the pump is actuated to force lubricant between the trunnions and bearings, thereby lifting the entire mill off of the bearings.

Where "starting jacks" are provided for the trunnion bearings of the larger sized mills, they should be filled with the same oil that is used for the lubrication of the trunnion bearings. Before starting the mill they should be pumped so as to insure having an oil film between the journal and the bushing. Ball Mill Relining
Ball mill trunnion. The ball mill trunnion is a key part to support and connect the cylinder, and is also the inlet and outlet channel of the material.

the mill is used primarily to lift the load (medium and charge). Additional power is required to keep the mill rotating. 8.1.3 Power drawn by ball, semi-autogenous and autogenous mills A simplified picture of the mill load is shown in Figure 8.3 Ad this can be used to establish the essential features of a model for mill power.
Summary of Grinding Basic Knowledge Ⅰ. Ⅰ. What are the types of mills and their salient features? According to the different media of the mill, it can be divided into: if the media is steel ball, it is called ball mill. If the medium is steel rod, it is called rod mill. If the medium is gravel, it is called gravel mill.
