The Karara Mine concentrator commenced operation in November 2012 to produce high-grade magnetite concentrate. The circuit consists of three stages of comminution plus magnetic separation at each stage for early gangue rejection. High-Pressure Grinding Rolls (HPGRs) are used for fine crushing, followed by ball mills and TowerMills in secondary and fine grinding duties respectively.


This newest fine classifier was conceived to combine with an upstream mill. The direct integration of the InlineStar classifier behind a mill creates a continuous grinding/classifying plant that reduces the number of required plant components. Available for separation limits from 2.5 to 60 µm (d97).


Grinding with Rösler: Perfectly prepared surfaces. Surface defects, mold release seams on components, die-cast surfaces, grinding grooves or roughness from additive manufacturing methods (3D printing) and other manufacturing processes need uniform, finely structured surfaces for further use or refining. Rösler mass finishing processes create ...


Weak magnetic mineral could use the strong magnetic mineral separation process after the magnetizing and roasting. Fine Grinding. In two stages grinding, stages separation, single weak magnetic flow, fine grinding means adding fine screen regrinding process to separate fine minerals timely and reduce the over-grinding.

2 Grinding Hub is the new trade fair and the new center for grinding technology. Frankfurt am Main – Fine machining requires a great deal of intuition. That is why many companies still take care of grinding and polishing manually. However, this can quickly become a source of high costs and inconsistencies, especially in series production.


Electrostatic separation was studied in a dry fractionation diagram to obtain β-glucan-enriched fractions from oat bran preparations. Ultra-fine grinding at ambient or cryogenic temperature was needed to achieve good dissociation between the macronutrients of oat bran particles.


BWH are also a voluminous material that is difficult to grind to very fine particle sizes, which can be achieved under cryogenic conditions. Therefore, we investigated the effect of fractionation by cryo-grinding and size separation (<56, 56–180 and >180 µm) on the dietary fibre content and bioactive profile of BWH.


PARTICLE SIZE REDUCTION. Particle size reduction and control often proves itself as a critical step in industrial solids processing systems. Often times it is used as a method for enacting positive results downstream, such as increasing surface area for efficient thermal treatment or milling and homogenizing a material for consistent mixing.
