This is observed to maintain an acceptable circulating load factor between 15 to 20 a target mill discharge residue on 90 microns sieve would be 40–50 for raw grinding and 10–20 for

Graphite Sag Mill Grinding Price In Czech Republic 20190204 AGSAG mills can accomplish the same Simplifying wet grinding with AGSAG mills AGSAG mills are often the optimum solution for wet grinding achieved in a slurry 50 to 80 percent solids AGSAG mills can accomplish the same size reduction work as two or stages of crushing and screening a rod mill and some or all of the work done

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

grinding rates The mill grinding rate through the size of interest 150 µm the circuit target P80 calculated from the plant survey data using the functional performance equation was 00568 t kWh The ‘energy specific cumulative grinding rates’ for the survey calculated from ball mill feed and discharge size distributions including

These tests were done with a ∅082 x 1 m grate discharge mill with a 30 mm graded ball charge and a 30 filling degree The mill discharge pulp density was increased from 688 to 759 solids The data is summarized in Table III The example in Table III illustrates that the density has a large influence on the grinding efficiency In this

Grate discharge Dry Grate discharge Wet Overflow discharge Wet Figure 85 Effect of mill filling on power draft for ball mills The data is taken from Rexnord Process Machinery Reference Manual Rexnord Process Machinery Division Milwaukee 1976 The effect of varying mill speed on the power drawn by the mill is shown graphically in Figure 84

SAG Mill Discharge Controlling the feed and discharge of a mill is mostly a stabilisation exercise – you need to be able to quickly and accurately control the mill feed rate If the mill feed setpoint is changed then the actual feed rate needs to stabilise at the new target in a short period of time

A regrind ball mill with a mix of small grinding media There is a limit on the fl ow rate of slurry that a ball mill can handle specially when processing extremely high tonnage McIvor 1990 recommends that the linear velocity of slurry in a ball mill Pulp density value causing discharge of small media in ball mills Mine Goldcopper
