subject: Usages And Working Principles Of Grading Crusher [print this page] Series MFP50A strength grading crusher is mainly applied to mining, metallurgy, chemical industry, coal industry brittle coarse bulk materials, intermediate broken, the feed size up to 350mm feed size minimum to 50mm can be confrontation the strength of 120MPa materials for crushing. Especially in the coal industry, the use of three machine crushing raw coal after iron removal, cleaning, without addition to the gangue, can be directly broken, broken out of the material, particle size uniformity, over broken low, thus simplifying the coal preparation technology, reduce the cost of investment and production. Therefore, since the market has been the attention and favor of many users.
Working principles of grading crusher:
From the analysis of minerals, physical properties, we know that the minerals in the compressive strength are much higher than the shear and tensile strength. The data indicate that the rock compressive strength and tensile strength, shear strength ratio of approximately 10:1, in tension and shear stress, the material is more easily broken. MFP series graded crusher is using this principle, the mixed material into the crusher, the material discharge between two teeth and the sidewall comb between the plates, so the product is broken after clearance by the control, not too large particle discharge. Thecompound has qualified fractionated products into the machine quickly discharge is no longer subject to the crushing effect. Therefore, the product powder production rate is much lower than conventional crushers. Substandard material was stuck between twoteeth roll by the role of shear stress and tension in the Roll is very likely that they be broken. The machine showed better screening effect and particle size control, product size whole. Therefore, the production machine shows a good granularity of control functions and classification functions, the machine named grading crusher.
