2 AG mill + a recycle crusher Competent ore - relatively homogenous (the recycle crusher is used to balance the rate of impact breakage within the circuit) 3 SAG mill (8 – 15% ball charge) Variable competency ore 4 High ball charge SAG mill (15 to 25% ball charge) Incompetent ore 5 Low ball charge SAG mill, high mill speed.

Where the SAG mill/ball mill circuit is the bottleneck in the processing plant the pebble circuit can be a significant factor in limiting overall plant capacity. The pebble circuit recirculating load can be very significant (depending on the ore characteristics and SAG mill operating dynamics).

Nov 18, 2014· If the reaction of mill capacity be much faster, the rate of feed would be set. [8] 8. Slide 8 effective factors for circulating load One of the problems of mentioned strategies is interaction between agents. One for thing, rising water cause to increase the circulating load which itself change the size of .

As a result, mines have shifted their emphasis in optimization from ball mills to SAG mills. The rock load in the mill essentially depends on ore characteristics and the discharge rate of broken particles through the discharge end. The discharge rate depends on how efficiently the .

Formula For Recirculating Load Of Cyclones And Mill. Inferential measurement models for the sag mill discharge are presented in the inferential models sectionhese models provide the discharge stream flow properties and size distribution and can be utilised for recirculating load and sag mill rock charge determination also.

Calculating a grinding circuit's circulating loads based on Screen Analysis of its slurries. Compared to %Solids or Density based Circulating load equations, a more precise method of determining grinding circuit tonnages uses the screen size distributions of the pulps instead of the dilution ratios. Pulp samples collected around the ball mill or rod mill and hydrocyclones, screen or ...

recirculating load – and at the same time preventing excessive equipment wear. The specific variables to be accommodated and the best strategy to control the grinding process will depend on the actual process circumstances, and the type of mill and drive involved. In modern grinding, ball mills and SAG mills are two types of mill commonly found.

The SAG mill feed is controlled by the mill weight, measured by 4 load cells on the mill bearing system. Therefore if the ore does not grind quickly enough in the SAG mills, the mill weight increases and the control system reduces feed to the mill to maintain the desired mill weight.

AG/SAG mill is inefficient in grinding particles of a certain size, typically in the range of 25-55 mm, i.e., pebbles. Therefore, cone crushers are often used as pebble crushers and integrated into AG/SAG mill circuits to break the critical size particles that accumulate in the mill and to increase the performance of the primary grinding circuits.

Calculate Sag Ball Mill Circulating Load. ... Formula For Recirculating Load Of Cyclones And Mill. The adopted hydrocyclone flow split parameter was 83.74%. This indicates that 83.74% of the hydrocyclone feed returns to the mill as circulating load. Considering the new feed is equal to 482 t/h, the calculated circulating load was equal to 2,482 ...

The purpose of the primary crusher is to reduce the ROM ore to a size amenable for feeding the secondary crusher or the SAG mill grinding circuit. The ratio of reduction through a primary crusher can be up to about 8:1. Feed: ROM up to 1.5 m; Product: -300mm (for transport) to -200mm (for SAG mill) Feed Rate: 160 to 13,000 tph
