Freda Rebecca SAG milling circuit optimisation CEEC

ABSTRACT Simulation work was carried out to analyse how feeding a finer size distribution to a single stage SAG mill in closed circuit with hydro cyclones at Freda Rebecca Gold Mine would affect throughput and specific energy consumption using an Excel based milling process simulator developed by Hinde, a comminution specialist who has worked for Mintek for many years.

Jan 01, 1987 The primary cyclone overflow is recycloned, the cyclone underflow being routed to a ball mill which is in closed circuit with a cyclone. Using linear screens, the circuit would be modified in that the S.A.G. mills would in a closed circuit with a 3 mm screen and become almost open circuit, the recirculating load dropping from 200 ...

Major Mines amp Projects Canadian Malartic Mine

Ore is processed at the Canadian Malartic mineral processing complex, which has a 55,000-tonnes/day nominal throughput capacity. Ore is transported to a crushing circuit and the crushed ore is stockpiled in a covered pile, then conveyed to the semi-autogenous grinding circuit followed by three identical ball mills, each in closed circuit with hydro-cyclones.

Upon receipt, the limestone was ground in a ball mill and screened to 100% passing 150 μm; P80 of the final product was about 30 μm. The limestone was of good quality and responded well in the process. Table 13-11: Limestone Analysis.ball mill machine Dealer, Fote

Ball mill closed circuit with hydrocyclones

Hydrocyclone control in grinding circuits - … A closed grinding circuit operating calcite of different hardness levels has been simulated. The calculations are based on pilot plant experiments with a ball mill and 150 mm-hydrocyclones.

High recirculating loads in Ball Mill Circuits Grinding

In my experience, from 200-350% re-circulating is normal for a closed circuit ball mill (reverse or direct). The selection of the hydro-cyclones, pumps and piping sizes all go hand in hand with mill sizing selection. Perhaps the most critical thing is selecting the hydro-cyclone vortex finder to ensure the cyclone overflow is clean.

SME Arizona 2016 Derrick Corporation

The grinding circuit consisted of two parallel ball mills in closed circuit with hydrocyclones. Each milling circuit was able to process at a rate of 35 t/h at a P80 of 120 microns. Solution. To improve the grind size fed to flotation, the cyclones on number 2 ball mill were replaced with two 5-deck Stack Sizers and 100 micron Polyweb panels ...

Extend cyclone life and increase operational FLSmidth

The SmartCyclone closed-circuit grinding optimisation system helps plant operators reduce cyclone-related process perturbations, while improving cyclone overflow particle size distribution. The controller unit allows the user to easily set operating parameters for any desired sensor.
