In ore dressing industry, when useful minerals are embedded in ores, in order to remove gangue from the ores and separate all kinds of useful minerals, the ores must be grinded into 0.1mm 0.3mm, sometimes even below 0.05mm 0.074mm. Fineness of grinding has a close relationship to beneficiation indexes. To some extent, the recovery rate of useful minerals is increasing with the decreasing of ore grinding fineness.
It is in the realm of ore dressing that crushing rolls found their greatest field of application, and, although a portion of this field has been taken over by the modern high speed gyratory crusher, and some of it eliminated by changing methods in concentration practice, a large number of roils are still in active service in ore dressing mills throughout the world.
