video of sag mill operation

That the Mill Operators' Conference series has reached its ninth inning is a testament to the regard with which it is held by mineral processing operators around Australia and overseas While more formal forums play an important role in the industry the Mill Operators' Conference has tended to lean as much if not more toward practical MILLING OPERATIONS Milling is the process of machining flat curved orMilling machines are basically classified as vertical or machine spindle are properly adjusted vertically for operation The plain vertical machines are characterized by a spindle The end milling cutter also called an end mill has teeth on the end as well as the

MEI Blog Where are SAG mills going?

Aug 25 2014In our recent conversation Prof Alban Lynch was very sceptical about where semi-autogenous grinding (SAG) mills have gone and thinks they have taken us along the wrong track He feels that they may be attractive in terms of high productivity but says that their energy efficiency is poor and I feel that these immense machines are going to turn into very large ball mills

Operation of SAG Mills The processing capability of a SAG mill is greatly affected by ore geology and operating variables within the mill The key issues broadly can be classified into two categories field of breakage and charge motion and flow through the grate and pulp lifters The field of breakage and charge motion are affected primarily

• Efficient operation even at higher mill speeds • Operator-friendly smooth mill operation • Significantly improve wear life • Can be precisely designed to handle the given capacity • Can be easily retro-fitted to existing mills The optimal performance of AG/SAG mills is the key to successful plant operation

SAG/AG SCU SAG/AG Sentinel Camera Unit (SCU) Concept of System The SCU uses the latest technology in high-definition imagery within a custom designed housing permanently affixed to the feed chute to provide a live audio and temperature feed in a running SAG mill and video feed from inside a stationary SAG mill

The faster the mill speed the greater the wear on the rods and liners So the general rule of thumb for rod mills is to operate no faster than the speed that will obtain the desired product size The operation speed of rod mills is generally determined by the Peripheral Speed of the Inside of the mill


Gearless Mill Drives

Benefits of continuous data acquisition from critical large drive systems in a mine operation (SME 2016) Frozen charge detection and automatic loosening with gearless mill drives (SAG Conf 2015) Mill drives the desire for increased power and the associated limits and conditions (SAG Conf 2015)

The Telfer Train 1 SAG Mill Operational data was collected for a six week prior to the installation of the Manta Cube Four sets of SAG mill operational data are graphed as histograms in Figure 10 These are 1 The SAG mill speed (rpm) 2 The SAG mill power (MW) 3 The SAG mill feed rate (tph) 4 The SAG mill weight (tonnes) Figure 10

The operator must select the amount of each size according to the current operational conditions as well as the total amount of ore to be processed in the SAG mill From a control point of view this system can be represented as a Multiple Input - Single Output system where the output is the total tonnage and the inputs are the feeders settings

INSTRUCTIONS TO LEARN HOW TO USE A LATHE The lathe is a machine tool used principally for shaping pieces of metal (and sometimes wood or other materials) by causing the workpiece to be held and rotated by the lathe while a tool bit is advanced into

The concentrator has a milling rate of 70 000t/d and is the largest single-circuit SAG-milling operation in the world The SAG mill provides feed for ball milling to produce flotation feed with the ball mills featuring variable-speed drives to enable the mills to handle the range of different ore hardness found at Antamina

SAG is an acronym for semi-autogenous grinding SAG mills are autogenous mills that also use grinding balls like a ball mill A SAG mill is usually a primary or first stage grinder SAG mills use a ball charge of 8 to 21% The largest SAG mill is 42' (12 8m) in diameter powered by a 28 MW (38 000 HP) motor

AG/SAG mills can accomplish the same size reduction work as two or three stages of crushing and screening a rod mill and some or all of the work of a ball mill Because of the range of mill sizes available AG/SAG milling can often be accomplished with fewer lines than in a conventional rod mill/ball mill
