In all ore dressing and milling Operations, including flotation, cyanidation, gravity concentration, and amalgamation, the Working Principle is to crush and grind, often with rob mill or ball mill, the ore in order to liberate the minerals. In the chemical and process industries, grinding is an important step in preparing raw materials for subsequent treatment.

The IsaMill is an energy-efficient mineral industry grinding mill that was jointly developed in the 1990s by Mount Isa Mines Limited ("MIM", a subsidiary of MIM Holdings Limited and now part of the Glencore Xstrata group of companies) and Netzsch Feinmahltechnik ("Netzsch"), a German manufacturer of bead mills. The IsaMill is primarily known for its ultrafine grinding applications in the ...

The main products of K&W Industrial Machinery Company are hammer crushers, jaw crushers, impact crushers, box crushers, vertical shaft impact crushers, single roller crushers and other products.

Grinding is by attrition and abrasion of the particles in contact with the high speed, small, circulating media. This breakage mode produces very fine sized particles at relatively low power consumption. IM grinding mechanism v2.jpg. At the discharge end of the IsaMill™, slurry and media reach the patented product separator.

IsaMill is a high-speed stirred mill that has been newly developed in the mineral industry for fine and ultrafine grinding. In this paper, a numerical model that is based on the discrete element method (DEM) was developed to study particle flow in a simplified IsaMill. The DEM model was validated by comparing the simulated results of the flow pattern, mixing pattern, and power draw with those ...

In short, IsaMill™ reduces the energy cost, media cost and capital cost of fine-grinding. The IsaMill™ is used extensively in base metals, PGM, gold processing and magnetite grinding applications. And the power capacity of an IsaMill™ ranges from 75kW to 3.8mW. IsaMill™ is the real-world specification of choice in: mainstream grinding.

It is a very thin cup-style grinding wheel which permits grinding in crevices and slot. Saucer Grinding wheels: Saucer Grinding Wheel is an exceptional grinding profile used for grinding twist drills and milling cutters. This finds wide usage in non-machining areas, as these saw filers are used by saucer wheels to maintain saw blades.

IsaMill technology was developed from the stirred milling technology of Netzsch Feinmahltechnik in the 1990's for use in the fine grained lead zinc ore bodies of Northern Australia in a drive to bring about a step change in grinding efficiency required to make these ore bodies economic to process.

Fine grinding produces a surface with little deformation that can easily be removed during polishing. Because of the drawbacks with grinding papers, alternative fine grinding composite surfaces are available, in order to improve and facilitate fine grinding, A high material removal rate is obtained by using grain sizes of 15, 9.0 and 6.0 µm.
