Abstract: The particle size distribution of ball mill grinding products is an important production index of the grinding operation, and due to its multivariate strong coupling and nonlinearity in the operation process, it leads to difficulties in achieving optimal control of the discharge particle size distribution. To this end, a reinforcement learning-based optimal …

The cost of a ball mill conversion from overflow to grate discharge is 'fairly' affordable at $65,000 for a 13′ x 15′ mill. This is only for the discharge head, grates and pulp filters (rubber). A comparison in laboratory of Overflow Discharge Ball Mill VS Grate Discharge Ball Mill.

Figure 5. High–low wave ball mill liner Materials The selection of the material of construction is a function of the application, abrasivity of ore, size of mill, corrosion environment, size of balls, mill speed, etc. liner design and material of construction are integral and cannot be chosen in isolation.

The speed of ball mill rotation is a critical parameter which determines the grinding efficiency and the end product quality. The optimum speed will differ depending on the mill's diameter, the size and density of the grinding media, and …

3. According to the discharging method of ball mill: • End discharge ball mill: This ball mill takes its head and end as the inlet and outlet respectively. • Central discharge ball mill: the inlet of medium unloading ball mill is at both ends, and the outlet is in the middle of the ball mill. 4. According to the ore discharge of ball mill:

The ore discharge side of the grid-type ball mill is equipped with a grid plate, and there are many discharge holes on the grid plate.The ground pulp passes through the grating plate and is lifted …

Technology and technics of ore preparation processes 5 The ore pretreatment flow charts in use at most high-productive processing plants designed in the last decade are based on semiautogenous (SAG) milling and involve as a rule primary wet autogenous mill (WAM) and a series of ball mills. WAM is customary chosen either based on examination
