In the case of the large SAG mill referred to in Fig. 1, the mill's initial volume is 757m 3 when new liners are installed, with the volume on average increasing to 792 m 3 at the end of shell ...

Overflow Versus Grate Discharge Ball Mills: An Experimental Investigation. In grate discharge mills the product is discharged primarily due to hydraulic gradient from the feed end to discharge end. Hence there is a possibility for much quicker transport of material through the mill, which is being accomplished in overflow mills by higher circulating load.

SAG Mill Shell Liners Spacing Grinding Classification ... Here for steel liners in a SAG mill, 10 to 15 mm (1/2 inch). Here on primary mills the liners aren't in there long enough to need filling in the gaps and I can't imagine any filler material that would last anyway.

discharge grates, along the pulp lifters and its discharge from the mill is an important contributor to the efficiency of the grinding process within a SAG mill. Poor transport of finer ground material can adversely affect grinding leading to excess energy consumption and overgrinding of fine material.

The discharge grates of the SAG mill were identified as a key component in the SABC circuit, and their design is a crucial factor in the mill's performance [17][18][19] [20] [21]. The initial ...

This paper will discuss the evaluation that addressed operator and maintenance observations, historical PLC data, and "crash stop" observations to calculate charge motion, packing between lifters, and slurry transport ...

Optimizing your SAG mill operation International Mining. Mar 21, 2007 Generally, the discharge from AG/SAG mills consists of one or both of the The mill discharge from these mills consists of slurry, which goes to the ball mills The grate, peripheral discharge trunnion supported mill and the

There is no best sag mill liner material. Different working conditionals need different material to selection of the material of construction is a function of the application, abrasive of ore, size of mill, corrosion environment, size of balls, mill speed, etc. liner design and material of construction are integral and cannot be chosen in isolation.

Grate Figure 4: Typical arrangement of Grate and Pulp lifters in SAG mills The design of grate/pulp lifters in SAG mills has a substantial impact on the behavior of the mill. If sufficient grate open area and pulp lifter capacity is not available, they will provide a high resistance to flow of slurry resulting in excessive amount of slurry resulting in slurry pool formation inside the mill.
