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.
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.
Ball Mill Recirculating Load The ball mill''s recirculating load was expected to be 250%. This corresponds to a volumetric flow of 2700m3/hr. However as with a large number of base metal milling circuits the Santa Rita milling circuit operates at a maximum recirculating load of 150%. The result of the lower recirculating load is that
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).
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 .

The crushed pebbles fall directly onto the SAG mill feed belt and return to the SAG mill. SAG mill product feeds two parallel ball mills of m× m (internal diameter×length), each with a MW twin pinion drive. The ball mills are operated at a ball charge volume of 30–32% and % critical speed.
The grinding circuit for the Copper Mountain project consists of one FL SAG mill and two FL ball mills. Figure 1 Overview grinding circuit The Copper Mountain SAG mill is 10363 mm [34 feet] in diameter and 6096 mm [20 feet] long. It is a grate discharge mill with an inside diameter of 10363 mm [34 feet] and a grinding length of 5334
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 continuously optimize mill operation, it is vital to obtain regular measurements of the ball load and pulp position.
The typical closed ball mill circuit to which CSE analysis can be applied is shown in Fig. 1. The extreme importance of the circulating load ratio (solids tonnage through the mill vs. the circuit) in determining circuit productivity was demonstrated by Davis (1925) and published by Gaudin (1939), as shown in Fig. 2. The circuit production rate

The ball mill is the most common ore grinding technology today, and probably more than 50% of the total world energy consumption for ore grinding is consumed in ball mills.
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 m; Product: 300mm (for transport) to 200mm (for SAG mill) Feed Rate: 160 to 13,000 tph
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.
