prediction of grinding media wear in sag mills

Jun 01 2005 Having been in a few process plants with SAG mills they are inefficient- as low as 1 since power costs are becoming a big issue there is lots of research being done ( try googling under SAG Mill efficiency) -technically I wouldn t consider them a crusher - they are grinding mills and some mill people might take offence- note that SAG mills are high compared to length-this is so the

MONSAG A new monitoring system for measuring the

A too large or too small load filling conducts to unproductive operating conditions or to an aggressive operation for the liners respectively A new monitoring system (MONSAG) intended for indirect measurement of the load filling of a SAG mill is presented The operating principle is based on the processing of electrical variables of the motor

What is a load cell?

Depending on the technical environment in which a load cell is installed – for example in a system for weighing containers or in a weighing cell under a conveyor belt – other loads in addition to the weight may occur Parasitic forces are forces acting on the load cell not only in the desired principal direction but also from the side from below or in some other way The load cell was

Morrell C

Applies to both SAG and ball mills with variants for grate-discharge and overflow mills This model was developed as part of the PhD thesis of Stephen Morrell at the University of Queensland and is the model used in the JK SimMet software for determining mill power draw It is described as the C-model and should not be confused with the more empirical D-model that has a form similar to

Autogenous and Semi

Some dry autogenous mills operating in Canada are 8 5 m in diameter and 1 5 m in length These are known as Aerofall mills The Cadia Hill (Australia) wet SAG mill is 12 2 m in diameter with a 20 MW motor and in 2004 was the largest diameter mill in operation in the world

Gearless mill drives

ABB's GMD is the most powerful mill drive system in the market to power semiautogenous (SAG) ball and autogenous (AG) mills This 'workhorse' for grinding operations combines a robust service-friendly and fit for purpose design to provide highest throughput reliability

SAG Mill

A SAG mill is characterized by its large diameter and short length It rotates tumbling its contents violently causing a breaking action The mill is lined with wear resistant steel liners which are fitted with lifters to assist with raising the load The liners are replaced as they wear and the lifting action has degraded The load - dry ore steel balls and water - occupies approximately

Load Cells

A wide selection of different designs from platform load cells to bending and shear beam s-type and compression cells The different load cell series cover nominal loads from 0 3kg to 500t Our range is rounded off by mounting units which supports a optimum alignment of the load cell protect the load cell against overloads or transverse loads and which greatly simplify assembly This is

Modelling SAG milling power and specific energy

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 will reach the expected power consumption but will not satisfy the
