Oct 15, 2020NLMK began implementing HPGR technology in each of the plant's four process lines in 2016. The first four grinding rolls supplemented traditional cone crushers and ball mills, and enabled the plant to boost the productivity of the sections by 12.5% and to grow iron ore concentrate output by 1 million mt to 16.6 million mt/y.

World's largest vertical roller mill underway at Shah Cement

The inauguration of the world's largest vertical roller mill for cement grinding completes a smooth commissioning process at Shah Cement in Bangladesh. With an 8.1-metre grinding table and six grinding rollers powered by an 11.6-megawatt gearbox, the FL OK™ 81-6 Mill has milled its first cement at Shah Cement's Muktarpur Plant

ABB ring-geared mill drives are to provide process and energy efficiency at Canadian gold mine. ABB has successfully commissioned four low-speed dual pinion drive systems at the Detour Lake gold mine in Ontario. These systems include the largest low-speed dual pinion mill

IDC Industries is installing their new Niles ZP24 gear grinder. This new machine, the largest of its type in Michigan, will allow IDC to better serve their customers in the steel, mining and paper manufacturing industries worldwide. IDC repairs, rebuilds and manufactures new gears and reducers from their new facility in Clinton Township, MI.

The power to spin the mill comes from large electric motors coupled to mill shell through a clutch and gear system. These electricity consumed by these motors is the largest cost and inefficiency. Most of the power is converted to heat in the charge (load) and a small percentage into ore breakage.

Oct 30, 2013Rexnord has completed the manufacture of its largest Falk Ring Gear in weight and horsepower — 250,000 pounds (113,000 kilograms) and 24,000 horsepower (18 megawatts). In terms of weight and horsepower, the ring gear is also one of the world's largest.

A comminution circuit is an important integral part of a mineral processing plant. Nearly 40% of the capital cost and 30 to 40% of the operating cost are taken up by the crushing and grinding circuit. Therefore, considerable care should be given to the design and selection of this circuit. Autogenous, semi-autogenous, and conventional grinding circuits have all been used for processing copper

The ball mill is a key piece of equipment for grinding crushed materials, and it is widely used in production lines for powders such as cement, silicates, refractory material, fertilizer, glass ceramics, etc., as well as for ore dressing of ferrous and non-ferrous metals. The ball mill can grind ores and other materials, wet or dry.

delivered the largest diameter gear-driven mill in Africa which also carries the world's largest spheroidal-graphite iron gear ever manufactured. The design and technology has room to go larger still, with gear-cutting facilities now allowing up to 16 m diameter. Despite its signifi cant foothold in Africa, the company continues to grow

The mill, however, could only be used where the current flow was suitable for grinding. The geared vertical-wheel mill was more versatile. Construction was relatively simple if the wheel was of the undershot kind, because the wheel paddles could be simply dipped in the stream flow, whether it was river, tide, or man-built millrace.
