For pulverizing, granulating and other size reduction applications we can provide used comminutors, roll compactors, chilsonators, oscillating granulators, rotary granulators, hommoloid mills, jet mills, air classifier mills, etc.
Size reduction is mainly done through crushers and mills. crushing and grinding are the two primary comminution processes. crushing is normally carried out on the runof.
States that the energy required for size reduction is proportional to the change in surface area of the pieces of food. p. d..ittingers constant for the size reduction of fine powders, in which large areas of new surface are being created, rittingers law fits the experimental data better.
Material trapped betweenolid plate andotating roll is shorn by its contact with the teeth on the roll. often the sheer crushing is combined with other crushing methods, such as compression, attrition, and impact, for mineral size reduction. for example, single roll crushers employ shear together with impact and compression.
