For this work the ultrafine grinds of the ball mill and stirred mill were selected for analysis of PGM liberation. This was based on associated flotation test work that showed significantly higher PGE recoveries for the stirred mill ultrafine grind than the ball mill ultrafine grind with similar solids recoveries and total concentrate grades.

Superior selectivity of minerals liberation in Titan M mill as compared to conventional ball mills (for example copper ore-dressing with Titan VSI mill yields 17 6 copper concentrate with 82 6 extraction as compared to 14 5 and 76 1 obtained with a ball mill grinding respectively).

What happens inside the machine After the very positive results we wanted to find out how and why the VeRo Liberator ® has this superior level of liberation. The working principle of the VeRo Liberator ® has been investigated and explained in collaboration with an expert in rock mechanics and engineering geology Prof. Dr. Christoph Lempp at Martin Luther University Halle-Wittenberg Germany.

Double Stage Ball Mills Occasionally the liberation requirement for an ore requires very fine primary grinding. Usually the most expeditious way to accomplish this objective is by double stage ball milling. Both mills are usually operated in closed circuit with separate classifiers.

conventional ball and tower mill technology however the power consumptions necessary to achieve the required fine liberation sizes made them uneconomic. Further the high rate of steel media consumption contaminated the mineral surfaces with iron resulting in poor flotation response post regrinding.

This was based on associated flotation test work that showed significantly higher PGE recoveries for the stirred mill ultrafine grind than the ball mill ultrafine grind with similar solids recoveries and total concentrate grades.

Dec 10 2016 · Ball milling of high carbon ferro chrome slag to liberate the alloy for gravity concentration. Milling experiments for a typical HCFeCr slag were conducted using a 0.303 by 0.282 m laboratory ball mill to establish liberation as a function of particle size and to determine the The combined relationship between the ball mill diameter

Cylindrical Ball Mills. The only cylindrical ball mills in common use are those of the grate discharge type the most important being the Marcy and the Allis-Chalmers mills. Fig. 10 illustrates the construction of the Marcy Ball Mill. The cylindrical shell and the feed and discharge heads are made of cast semi-steel.

Full densimetric analyses indicate that mineral liberation of the product crushed by the jaw crusher is better than that by the ball mill at each fraction. For sizes of −0.125 mm 0.074 mm and −0.074 mm yields of the product with ash content 11 comminuted by jaw crusher are nearly 20 higher than that by the ball mill.
