Sag Mill Grates

Overflow VS Grate Discharge Ball or Mill Why Retrofit

The cost of a ball mill conversion from overflow to grate discharge is ‘fairly’ affordable at $65,000 for a 13′ x 15′ mill. This is only for the discharge head, grates and pulp filters (rubber). A comparison in laboratory of Overflow Discharge Ball Mill VS Grate Discharge Ball Mill.

of grate/pulp lifter design in AG/SAG mill discharge. The current understanding from literature lacks knowledge of mill content size distribution and its effect on discharge through the grate at various aperture sizes and radial positions. It also indicates that in

Mill power draw models SAGMILLING.COM

The design of mill liners and SAG mill discharge grates will have a large effect on how efficiently the mill operates and the circuit throughput. All models generally assume that a mill is fitted with "efficient" liners and that the grate design neither limits passage of pebbles (and pulp) nor permits re-circulation of pulp back into the mill.

SAG MILL DISCHARGE SCREENS-TROMMEL vs. VIBRATING Tony

SAG MILL DISCHARGE SCREENS-TROMMEL vs. VIBRATING Tony Moon, RTZ What I’d like to talk about is probably one of the nastiest bits of mill design for a grinding circuit, and that is the choice of what do you use on a SAG mill discharge? Do you use vibrating screens or trommel screens? What many of you probably don’t realize is that at

Optimizing your SAG mill operation International Mining

The commercially viable and industry accepted alternate is a grate discharge trunnion supported mill or a grate discharge shell supported mill using pulp lifters. The only way to eliminate the problem of flow-back and carry-over of slurry and pebbles is by optimizing the design of the discharge arrangement.

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 over-grinding of fine material. This paper uses a 1-way coupled DEM-SPH

SAG Mill Liner Design Mineral Processing & Metallurgy

To a more significant degree than in other comminution devices, SAG Mill Liner Design and Configuration can have a substantial effect mill performance. In general terms, lifter spacing and angle, grate open area and aperture size, and pulp lifter design and capacity must be considered.

Grinding Mill Design & Ball Mill Manufacturer

All Grinding Mill & Ball Mill Manufacturers understand the object of the grinding process is a mechanical reduction in size of crushable material. Grinding can be undertaken in many ways. The most common way for high capacity industrial purposes is to use a tumbling charge of grinding media in a rotating cylinder or drum.

• Lower maintenance costs because no extra mill shutdowns are required to clean the grates, which take about nine hours per month. • Improved operational safety because rubber does not 'impact weld' like metal during regular mill operation so the grates can be removed easier. As a result, the grates are easier to remove when needed.
