The inference from this observation was that breakage of coarse rocks is limiting the circuit at the SAG mill. In consequence, the ball mill appears starved of feed. Applying an in-house model of the power that can be drawn by an overflow ball mill showed that the installed ball mill is incapable of drawing the power available from the motor.
Bond ball mill work index for the ore samples collected from surveys 3 and 4 was 17.2 and 18.7kWh/t, respectively. The fact that the operating work index is lower than the Bond work index indicates the circuit is achieving exceptional energy efficiency. This confirms the observation
The cost of edge drive is low, but the pinion needs to be replaced every 2-5 years. Edge drive is mainly used in coal mills and mills with small power. The girth gear(big ring gear) and pinion are the key of the edge transmission device. Their reliable operation is directly related to the stable production of the mill.
seen, the vertical mill consistently presented lower net specific energy consumption than the ball mills which operate on the same circuit. The averages were 11.3, 11.7 and 6.5 kWh/t respectively for ball mill 01, ball mill 02 and vertical mill. Figure 5 – Net specific energy consumption of regrinding circuit.

Principle of Ball Mill : Ball Mill Diagram. • The balls occupy about 30 to 50 percent of the volume of the mill. The diameter of ball used is/lies in between 12 mm and 125 mm. The optimum diameter is approximately proportional to the square root of the size of the feed. The shell is rotated at low speed through a drive gear (60-100 rpm) and ...
Studies Show Snags to Mill Optimization. More than 100 virtual operators have been deployed over the course of three years at Los Bronces mine. Above, the Los Bronces mine milling control room in Chile. (Photo: Anglo American) Two studies identify obstacles to SDGs, while a major miner announces the windfall from deploying automation.

Your Ball Mill reflects years of advancement in grinding principles, materials, and manufacturing techniques. It has been designed with both the operators and the erectors viewpoints in mind. Long uninterrupted performance can be expected from it if the instructions covering installation and maintenance of the mill are carried out.
It is commonly reported that mill performance improves as lifters wear and that the installation of new lifters can often lead to reduced grinding (Kalala et al., 2008; Toor et al., 2015). The ...

The grinding process of the ball mill is an essential operation in metallurgical concentration plants. Generally, the model of the process is established as a multivariable system characterized with strong coupling and time delay. In previous research, a two-input-two-output model was applied to describe the system, in which some key indicators of the process were …
