To liberate individual minerals trapped in rock crystals (ores) and thereby open up for a subsequent enrichment in the form of separation. To produce fines (or filler) from mineral fractions by increasing the specific surface. Grinding takes place in more "open" space which makes the retention time longer and adjustable compared to crushers.

Grinding is a machining process improving the surface finish of the job and producing small chips. The tool used for this process is the grinding wheel. It is a cutting tool in which millions of microscopic abrasive grains are bond together. Here, each abrasive grain acts like a spiky tool. As shown in the image, the abrasive grains are held ...

New Surface Formed by Grinding When a uniform particle is crushed, after the first crushing the size of the particles produced will vary a great deal from relatively coarse to fine and even to dust. As the grinding continues, the coarser particles will be further reduced but there will be less change in the size of the fine particles.
