SAG Discharge Cone progressiverubber.com

PRI worked closely with the customer to develop a design that would help decrease their downtime on their 34’ diameter by 17’ long SAG mill. The cone supplied with PRI ceramic Matrix technology lasted over 12 months! This also led to more business at the site …

Improved Relationships for Discharge in SAG AG Mills

size distributions in AG/SAG mills. The existing models and understanding of grate discharge and classification are known to be flawed and have been identified as one of the key limitations in AG/SAG modelling. The aim of this thesis is to improve on the current understanding of discharge in the SAG…

Polycorp AG SAG Mill Liners

AG/SAG Mill Liners. We have supplied rubber pulp lifters for SAG mills up to 40 ft in diameter. We are pioneers in the design of both radial and curved pulp lifters, also design and manufacture Rubber / PolyStl™ grates and discharge systems. Mining.

SAG mill pulp lifter design discharge and backflow

Conventional straight-radial semiautogenous grinding (SAG) mill pulp lifters suffer from incomplete discharge of the rockportion of the charge. The resulting backflow of undischarged rock limits ...

Morrell C model SAGMILLING.COM

Morrell C-model. 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.


LG A mill power equation for SAG mills. Minerals and Metallurgical Processing. Feb 1990 pp57-62. Gross power No load power Net power drawn by the charge (8.13) The net power is calculated from Net power KD2.5L e! c./ Watts (8.14) In equation 8.14, D is the diameter inside the mill liners and Le is the effective length of the mill including the ...

An ITT Brand Goulds SRL

The primary ball/SAG mill discharge is one of the most severe duties in mineral processing. The suction wearplate is subjected to rapid wear due to high solids concentration and the coarse nature of the slurry. Goulds developed a proprietary process to locate and mold ceramic rods into the rubber liner for the optimum combination of hardness

What's the Difference Between SAG Mill and Ball Mill

Nov 26, 2019 Based on the high throughput and coarse grind, AG mills produce coarse grinds often classify mill discharge with screens and trommel. SAG mills grinding media includes some large and hard rocks, filled rate of 9% – 20%. SAG mill grind ores through impact, attrition, abrasion forces.

Mill drives the desire for increased power and the

consideration of a larger mill installation with diameter at the design stage. Between 2001 and 2008, a limit of 22 MW was placed on SAG mill drives (as GMDs) by some operators and principal motor designers/manufacturers until the reasons for known problems in design or manufacturing were better understood and resolved.

Simulation of Material Transport in a SAG Mill with

Sep 20, 2018 A Discrete Elements Method (DEM) study of load movement within a SAG mill 12,192 7620 (40′ 25′) in normal operating conditions is performed. The purpose is to determine how the geometry of the lifters affects the kinetics of the load inside the mill. Specifically, the changes produced by the incorporation of inclined lifters and spiral or helicoidal pulp lifters to the kinetics are ...

SAG Mill Pulp Dischargers Grinding amp Classification

Modern Semi-Autogenous (SAG) Grinding Mills can be up to 12 metres in diameter (absorbing up to 20 MW of power) and need to discharge over 2500 tonnes per hour of solids via pulp lifters. Pulp lifters take the form of a radial array of “box-section” channels mounted inside the discharge end wall of the mill.

SAG Mill Liner Design Mineral Processing amp Metallurgy

Jun 06, 2016 Experience to date on mills ranging from 5.5 m (18 ft.) diameter to 11.0 m (36 ft.) diameter shows that capacity is equal or greater than with conventional lining at the same unit power consumption. Fully Autogenous Grinding (FAG) Mills. End and shell liner design in these mills is much the same as for SAG mills.

PDF Influence of feed size on AG SAG mill performance

performance of a large diameter sag mill is shown in Figure 4 page I-208. ... but the specific energy decreases more) because the mineral goes faster to the mill discharge, leaving a greater part ...


the data base that the model has been tested against has increased to over 150. AG/SAG mills in the data base are up to 40ft in diameter and ball mills are up to 26ft in diameter. The measured gross power draws from these mills are plotted against the model …

Autogenous and Semi Autogenous Mills FLSmidth
