grinding mill, is generally used in mineral processing concentrator, processing materials include iron ore, copper ore, gold ore, molybdenum ore and all kinds of nonferrous metal ore. the core function of the ore ball mill is to grind the materials, and also to separate and screen different mineral materials sag mill grinding circuit designthe design of large mills has become increasingly more complicated as the size has increased and there is little doubt that without sophisticated design procedures such as the use of the finite element method the required factors of safety would make large mills prohibitively expensive. in the past the design of small mills, up to +/ 2,5 metres diameter, was carried out using empirical formulae with relatively large factors of safety. as the diameter and length of mills increased several critical problem areas were identified. one of the most important was the severe stressing which took place at the connection of the mill shell and the trunnion bearing end plates, which is further aggravated by the considerable distortion of the shell and the bearing journals due to the dynamic load effect of the rotating mill with a heavy mass of ore and pulp being lifted and dropped as the grinding process took place. incidentally the design calculation of the deformations of journal and mill sh see full list on 911metallurgist.com kidston gold mines is a 14 000 tonnes per day rated operation located 280 kilometers west of townsvilie in queensland. the principle shareholder is placer development . kidstons orebody consists of 44.2 million tonnes graded at 1.79 g/t gold and 2.22 g/t silver. production commenced in january, 1985, and despite a number of control, mechanical and electrical problems, each month has seen a steady improvement in plant performance to a current level of over ninety percent rated capacity. see full list on 911metallurgist.com the cyanidation plant consists of a primary crushing plant, a semiautogenous grinding circuit, agitation leaching circuit, cyclone wash circuit, gold recovery circuit and carbon regeneration circuit. the grinding circuit comprises one 8530 mm diameter x 3650 mm semiautogenous mill driven by a 3954 kw variable speed dc motor, and one 5030 mm diameter x 8340 mm secondary ball mill driven by a 3730 kw synchronous motor. four 1067 x 2400 mm vibrating feeders under the coarse ore stockpile feed the sag mill via a 1067 mm feed belt equipped with a belt scale. feed rate was initially controlled by the sag mill power draw with bearing pressure as override. integral with the grinding circuit is a 1500 cubic meter capacity agitated surge tank equipped with level sensors and variable speed pumps. this acts as a buffer between the grinding circuit and the flow rate sensitive cycloning and thickening sections. see full list on 911metallurgist.com the kidston plant was designed to process 7500 tpd fresh ore of average hardnessbut to optimise profit during the first two years of operation when softer oxide ore will be treated, the process equipment was sized to handle a throughput of up to 14 000 tpd. some of the equipment, therefore, will become standby units at the normal throughputs of 7 000 to 8 000 tpd, or additional milling capacity may be installed. the sag mill incorporates a design which allowed expedient manufacturing to high quality specifications, achieved by selecting a shell to head to trunnion configuration of solid elements bolted together. this eliminates difficult to fabricate and inspect areas such as a fabricated head welded to shell plate, fabricated ribbed heads, plate or casting welded to the head in the knuckle area and transition between the head and trunnion. motor torque at full load current is 214.4 knm up to base speed (176 rpm) and 184.0 knm from base to top speed. maximum accelerating torque is see full list on 911metallurgist.com considerable variation in ore hardness, the late commissioning of much of the instrumentation and an eagerness to maximise mill throughput led to frequent mill overloading during the first four months of operation. the natural operator overreaction to overloads resulted numerous mill grindouts, about sixteen hours in total, which in turn were largely responsible for grate failure and severe liner peening. first evidence of grate failure occurred at 678 000 tonnes throughput, and at 850 000 tonnes, after three grates had been replaced on separate occasions, the remaining 25 were renewed. the cylinder liners were so badly peened at this stage that no liner edge could be discerned except under very close scrutiny and grate apertures had closed to 48 percent of their original open area. the original sag mill control loop, a mill motor power draw set point of 5200 amperes controlling the coarse ore feeder speeds, was soon found to give excessive variation in the mill ore charge volume a see full list on 911metallurgist.com design changes to date have, predictably, mostly concentrated on improving liner life and minimising discharge grate damage. four discharge grates with thickened ends have performed satisfactorily and a mk3 version with separate lifters and 20 mm apertures is currently being cast by minneapolis electric. cylinder liners will continue to be replaced with high profile lifters only on a complete reline basis. while there is the problem of reduced milling capacity with reduced lifter height towards the end of liner life, it is hoped to largely offset this by operating at higher mill speeds. mill feed chute liner life continues to be a problem. the original chromemoly liners lasted some three months and a subsequent trial with 75 mm thick clamped linhard (rubber) liners turned in a rather dismal life of three weeks. see full list on 911metallurgist.com 3ore processing videos and hd footage getty imagesfind professional ore processing videos and stock footage available for license in film, television,
