01.01.2011· The mill was loaded with 26.3 kg of 5-mm steel balls, corresponding to 60% of the mill volume filled by a ball bed. A steady-state condition was established by feeding the sand at a given feed rate until the solid discharge rate attained the same value as the feed rate and the size distribution of the product did not change with time. The RTD was measured by carrying out an impulse test using ...
As the ball charges and narrow, the size fractions of the samples have different masses. In this research, the grinding efficiency has also been observed through the specific mill throughput per ground product, per unit mass of the ball charge Q s (kg/h/kg). The specific throughput has been calculated at .

Ball mills are usually the largest consumers of energy within a mineral concentrator. Comminution is responsible for 50% of the total mineral processing cost. In today's global markets, expanding mining groups are trying to optimize mill performances. Since comminution is concerned with liberating valuable minerals for recovery in the separation process, it is crucial to run the mills at the ...

The mill discharge from these mills consists of slurry, which goes to the ball mills for further grinding, and coarse pebbles/rocks, which are crushed and sent back to the mill. To maximize the capacity of these circuits, the general practice is to use grates with pebble ports (reaching 100 mm) instead of normal grate openings to increase the pebble removal. In addition, operating mills at ...

the mill discharge from ball mill 1 will increase. With the same water addition to sump 1 the particle size of Cyclone 1 overflow will increase. This will decrease the ratio, and hence the control loop will add more water to keep the ratio constant. However, the amount of slurry reporting as fresh feed to the second milling circuit will increase.
