Grinding - Grinding Isamill

Media recirculates between the rotating discs distributing grinding action throughout the IsaMill™. 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.

Fine Grinding as Enabling Technology – The IsaMill

Process, the Isamill grinds and activates minerals to a point where bacteria or pressure are no longer required, and leaching can be carried out in simple open tanks. The extremely high power intensity in the IsaMill compared with other grinding methods suggest it would enhance mechanical activation.

ISAMILL FINE GRINDING TECHNOLOGY AND ITS INDUSTRIAL ...

The compact IsaMill operates under pressure with "stage-by-stage" grinding occurring between the high speed rotating discs, which ensures grinding events are evenly distributed throughout the grinding chamber. This homogeneous grinding mechanism results in significant improvements to the particle size distributions from the feed to the product.

Ultrafine Grinding and the IsaMill™ Technology - About ...

The IsaMill™ produces a sharp size distribution in open circuit, as the feed must pass through multiple distinct grinding zones in series before reaching the Product Separator. This plug flow action ensures no short circuiting, and efficiently directs energy to the coarser feed particles.

grinding mechanism results in significant improvements to the particle size distributions from the feed to the product. The IsaMill Technology grinds the particles requiring size reduction, without over-grinding material at or below the required P80. The uniform grinding mechanism and high speed are reasons why IsaMill scale-up is 100% direct from

IsaMill - NETZSCH Grinding Dispersing

The patented IsaMill is a transformation in grinding technology based on high intensity stirred milling. The IsaMill was developed for fine grained orebodies that needed a step change in processing efficiency to be economic. The IsaMill significantly reduces the energy requirement, and media and capital costs 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. While it's best known for achieving unequalled results in 'ultrafines', IsaMill™ is in fact an all-rounder, and roughly half our mills are processing feeds greater than 100 microns.

Superior product size distribution - IsaMill™ Advantages ...

Grinding performance of an IsaMill™ is fundamentally different from a ball mill. The impact mechanism and long residence times in ball mills combined with inherent inefficiencies of cyclones results in indiscriminate grinding and poor size distributions. This leads to slimes generation, higher reagent consumption and energy wastage.
