The ball mill treatment reduced chromite grains greater than 15.77 µm down to sizes less than 11.15 µm in diameter, and thus released chromite-bound Cr(VI) for sulfide reduction. Magnesioferrite encapsulated Cr(VI) was released and reduced similarly with grain size change from 15.77 to 37.5 µm to below 15.77 µm. Besides, the improved 10% of ...
chromite rich fraction through the ball mill. This circuit is typical of a UG2 plant in which maximum silicate with minimal chromite breakage is targeted. As a result of the circuit change an opportunity for optimisation around the industrial scale ball mill was considered for this study.
Ball mill for chromite. ball mill is an important beneficiation equipment which is widely use in the mining industry and powder production plant, it mainly use wet ball mill when it is applied for the mineral processing plant, such as iron ore processing plant, lead ore processing plant,nickel ore processing plant, chrome ore processing plant, and so on, and the ball mill can be called.
Approximately 35% of the mill volume, including the interstices within the ball bed, was loaded with 25.4 mm steel balls weighing 8 kg. Each grinding test was performed with 0.63 kg of the chromite ore or clinker for various grinding times from 0.25 min up to 16 min. Mill product size distributions were obtained by dry sieving. 3.

The Ball Mill. Much like all types of mills, the Ball Mill's purpose is to grind and blend material into smaller pieces. To do this, the material is fed into the cylinder at an angle and then rotated inside. During rotation, the material travels up the internal wall of the cylinder and then falls back down to the bottom of the structure.
Chromite beneficiation process is efficient and simple, which can achieve the best effects. The qualified materials are evenly fed into the ball mill for grinding, then chromite power is sieved by the spiral classifier. The versize chromite power return to the ball mill for re-grinding. Gravity separation is the main method for chrome ...
