Working Principles

        After being crushed, the feed stock is carried to the superfine ball mill with a conveyer. The milling balls in the ball mill will impact and grind the feedstock by the energy of the rotating ball mill. The crushed feedstock is carried to the self-diffluent micro-powder classifier through a discharging chamber, and completely mixed with air forming a fluid that is classified into coarse and fine powders under the forces of centrifugal classifying blades and the draught of air. The qualified fine powders are collected with a cyclone collector and bag collector. The coarse powders are sent to be recrushed in the ball mill through the lower part of the classifier.

Performance and Characteristics

        The superfine classifying ball mill , is a newly developed combination the technology of super-fine milling and self-distributing fine powder classification, with characteristic of energy saving and high efficiency.
◇ The special characteristics of new superfine classifying ball mill is the revolutionary advancement of energy saving and precision of classification, it can save much more than 40% than the other mill machine( same product).
◇ Can be adjusted from 300-2500 mesh in one time, add one set of classifier system ，the finer can be reach d97≤2um （6250mesh） though the second classification， reaching the worldclass level in dry classification. Thanks for the application of the self-diffluence classifying technology, high precise classification, precise cutting point, large capacity and no coarse particle in the product have been transformed into reality; the handling capacity of one large series of Model-LHB Classifier can reach 80 ton/hr. The consumption is only half of the same product, and the extraction rate of fine powder improved by 50%, compared with the same mill.
◇Superfine ball mill has been made an improvement based on the traditional type, and the apportion of the media is much more reasonable, the percentage yield of the powder is improved largely.
◇ According to the different materials, chose different lining and grinding ball to protect the purity and the whiteness of the product.
◇ Lower installed power, and small small floor area, the total investment of the building and auxiliary equipment can be reduced 50% compare with the other ball mill production line.
◇Lower rate of fault, stable operation; the system is controlled by frequency conversion, high automatically, designed by flow negative-pressure, good working environment.
◇Large capacity, can carry on the turn-keys project with annual production capacity of 0.5-500000 tons.
◇There are two sets of superfine classifier ball mill Impact Mill production line in our company, can do 1:1 trail for the customers at any time.
