Xstrata Zinc Sag Mill Power Load Control

Xstrata Zinc: SAG Mill Power / Load Control Mipac

The new SAG mill at Xstrata’s Zinc/Lead Concentrator had not been performing to expectation. The mill was operating below design power (2100kW), and at lower rock loads leading to reduced throughput and a shorter liner service life.

A control strategy recently implemented on a large variable-speed SAG mill at MMG’s Century Zinc operation in Australia is shown in the chart (found on pg. 32). In this case, mill speed is the primary manipulated variable used to control mill load.

ball mill work index was averaging only 11.6 kWh/t, which is not hard. A rod mill work index fi gure was not found but was thought to be in the 16 kWh/t to 18 kWh/t range. The Xstrata Zinc 22 ft ID × 40 ft EGL over ow ball mill fl was installed at Mt Isa in 2009

Fuzzy Logic Control On a SAG Mill ScienceDirect

1/1/2013 In 2005, a rule based approach was developed but it was abandoned as it could not handle disturbances and new control objectives (Bartsch et al., 2008). 284 SAG MILL CONTROL Fig. 3. SAG circuit 6. 6.1 Objectives CONTROLLER DESIGN The goals are to reduce power consumption per ton of ore, increase throughput, protect linings and stabilize quality and operation.

Gearless drive systems for belt conveyor and grinding mills

The SAG mill was fitted with a gearless drive with a power rating of 24 MW and the ball mills were also fitted with gearless drive systems, each providing 16.4 MW.

IsaMill Wikipedia

The IsaMill is an energy-efficient mineral industry grinding mill that was jointly developed in the 1990s by Mount Isa Mines Limited ("MIM", a subsidiary of MIM Holdings Limited and now part of the Glencore Xstrata group of companies) and Netzsch Feinmahltechnik ("Netzsch"),

sag mill feed size distribution ME Mining Machinery

distribution affects the SAG mill load and the load affects directly the mill power and the efficiency of the mill operation (Van Nierop and Moys, 2001). If a SAG mill has been designed with a conventional power or specific energy model which do not con-sider the projected feed size distribution it is likely that this mill
