Highly efficient and low cost mining ball mill used in the quartz sand grinding factory
Introduction of Quartz Sand Grinding Ball Mill
After being milled, 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 re-crushed in the ball mill through
the lower part of the classifier.
Characteristics of Quartz Sand Grinding Ball Mill
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.
1. 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.
2. Can be adjusted from 300-2500 mesh in one time, add one set of classifier system £¬the finer can be
reach d97≤2um (6250 mesh) though the second classification£¬it is the top of the drier method both in
the world.
3. By adopting self-distributing technology, high precision, correctly cutting point, large capacity, the
largest capacity of an single LHB type classifier can be reach 100 t/h; lower consumption, as the same
capacity the consumption reduce 50% compared with the other equipment, high efficiency of the classifier,
as the same consumption, the extraction rate of the fine powder is increase by 50%.
4. Superfine ball mill has made the creative based on the traditional, and the apportion of the media is
much more reasonable, the percentage yield of the fine is improved largely.
5. According to the different materials, chose different lining and abrasives to protect the purity and the
whiteness of the product.
6. Lower installed power, and small area division, the total investment of the building and auxiliary
equipment can be reduced 50% compare with the other ball mill production line.
7. Lower rate of fault, stable operation; the system is controlled by frequency conversion, high
automatically, designed by flow negative-pressure, good working environment.
8. Large capacity, can carry on the capacity of 0.5-50 tons/per year turn-keys project.
