### grinding ball mill discharge rate - …

AG and SAG mills are now the primary unit operation for the majority of large grinding circuits, and form the basis for a variety of circuit configurations. SAG circuits are common in the industry based on: High single-line capacities (leading to capital efficiency) The ability to mill a …

### Calculate Ball Mill Grinding Capacity

The sizing of ball mills and ball milling circuits from laboratory grinding tests is largely a question of applying empirical equations or factors based on accumulated experience. Different manufacturers use different methods, and it is difficult to check the validity of the sizing estimates when estimates from different sources are widely ...

### ball mill discharge grind size - Grinding & …

I am working in a plant with single stage grinding using a ball mill we operate the mill power at around 1400KW& the feed size is 20mm. we use 78mm/64mm steel balls. the ball mill is in closed circuit with classification cyclones. there are 3 cyclones and we operate 2 with a pressure of about 90KPa.

### Optimization of mill performance by using

to the volumetric mill filling which influences grinding media wear rates, throughput, power draw, and product grind size from the circuit. Each of these performance parameters peaks at different filling values. In order to contin-uously optimize mill operation, it is vital to obtain regular measurements of the ball load and pulp position.

### Analysis of specific discharge rate functions in ...

A correlation between discharge rate and mill throughput rate increase was found to exist (Genç, 2008). Sub-factors influencing the material discharge through the mill could be the ball size distribution, air flowrate through the mill, grinding aid, diaphragm design, blockage on the diaphragm. 3.3.1. Coarse particle accumulation affect

### Ball Mill Design/Power Calculation

The basic parameters used in ball mill design (power calculations), rod mill or any tumbling mill sizing are; material to be ground, characteristics, Bond Work Index, bulk density, specific density, desired mill tonnage capacity DTPH, operating % solids or pulp density, feed size as F80 and maximum ‘chunk size’, product size as P80 and ...

### Overflow VS Grate Discharge Ball or Mill - Why …

Allow me to compare: Ball mills can be of the overflow or of the grate discharge type. Overflow discharge mills are used when a product with high specific surface is wanted, without any respect to the particle size distribution curve.Overflow discharge mills give a final product in an open circuit.
