of the Bond ball mill grindability test. For all model based methods, a reliable method to calculate mill power draw for a given mill is required for the calculation of power draw. Morrell 1996 proposed a mathematical model for autogenous, semi-autogenous and ball mills which is based on the motion of grinding charge inside the mill.

The absorbed power is calculated by multiplying the torque on the driving shaft with the shaft speed radsec and hence excludes any losses associated with the gearbox and motor. The pulp weight in the mill is obtained by subtracting the mill weight during the test from the empty mill weight, including the ball charge, at the start of the test ...
Mill power Usually, plant operators use mill power readings as an indicator of ball filling degree and, often, try to keep it at the maximum level. It is well known that the mill absorbed power depends on operating parameters other than ball level, such as pulp density and liner configuration. Figure 2 shows that there is no linear relation between
the methods of sizing the milling power based on laboratory tests on grindability of minerals. This article considers one of such methods allowing determination of mill characteristics based on the Bond work indexes of crushing, rod milling and ball milling. The authors exemplify the
The mill performance is evaluated and recommendations are formulated based on the past history of the mill operations, inspections, process measurements, feedproduct characteristics and grinding performance, in order to improve mill output and reduction in power consumptions in the ball mill system. DIAGNOSTIC STUDY History of mill operations
1 The power consumption level for grinding is lower than that of tube ball mill. 2 The remaining time of raw materials in this type of mill is much shorter than that in tube ball mill therefore, the crushing process and mixing process became more harmonized and this contributes to quality control.
There are six parallel conventional milling circuits at Palabora Mining Company. Each milling circuit consists of a rod mill followed by a ball mill in series. Crusher product -9 mm is fed to the rod mill, and the water is fed in ratio to the ore feed mass. The rod mill discharge is pumped, without any further water addition, to the first ...
and the specific net mill power for a tumbling mill, which is not affected by the operating parameters. Nomura S. et al. 1994 also confirmed this relationship. Two important factors should be determined before carrying out experiments in a mill, namely the ball filling J and the powder filling f c. J is the ball
base are up to 40ft in diameter and ball mills are up to 26ft in diameter. The measured gross power draws from these mills are plotted against the model predictions in Figure 1. As indicated by this data base the accuracy of the model 1 standard deviation is 4.6. How to Use the Model . Inputs to the model are made in three windows, viz Mill ...
Despite the variety of used mill designs, the ball drum mills were the most popular ones - 85. Regardless of a mill design the grinding of material in them is performed by blows, crushing and abrasion. The calculations and experimental studies indicate that no more than 5 of the supplied energy is used directly for
