Dry Limestone Ball Mill Calcium Carbonate Powder Plant

WORKING PRICIPLE

This system includes crushing, grinding, grading, packaging, bin, conveyor, hoist, etc, the material after coarse broken by transfering equipment into raw materials warehouse, through raw materials warehouse of controllable feeder into ultrafine mill, grinding machine grinding media with energy gained by the mill rotates to grinding and polishing grinding materials, The crushed material enters the air flow classification for classification through the unloading bin to realize the separation of coarse and fine powder. The qualified fine powder is collected by the collector, the coarse particles are re-entered the ball mill for crushing by the discharge valve of the Classifier, the fine powder is filtered by the Dust Collector, and the purified gas is discharged by the induced draft fan.

Performance advantages and characteristics 

The ultra-fine ball milling classification production line is an international standard non-mining processing production line, which combines the ultra-fine ball milling technology with the self-split micro powder classification technology perfectly. The ball mill can be connected with multiple grading machines in parallel grading, also can be connected with multiple series grading, at the same time to produce multiple particle size products.

● The ball mill classification production line has made revolutionary progress and breakthrough in energy saving technology and classification accuracy, saving more than 50% compared with other ball mill classification production lines and other types of mills. High classification precision, accurate cutting point, large processing capacity;

● Grading fineness 200~6000 mesh arbitrary adjustment, up to the current domestic and foreign dry grading high level; The new self-split high concentrated phase classification technology is used in the classification production line of ultrafine ball mill.

● Ultra-fine ball mill for innovative design, crushing efficiency greatly improved, grinding medium ratio science, can effectively produce a large number of fine powder;

● The hard minerals can be designed without iron pollution. The lining plate and grinding body are made of alumina ceramic, quartz, SILEX or special materials. The grinding medium is rationally proported according to the product requirements, and the filling rate is high to ensure the purity and whiteness of the product.

● When grinding ultra-fine powder, add grinding additives, improve grinding efficiency, optimize the matching of drive and grinding energy consumption, greatly save energy consumption and classifier to form a closed system, negative pressure transportation, dust-free;

● Low equipment failure rate, stable operation; The system adopts intelligent frequency conversion control, high degree of automation; Negative pressure flow field design, excellent production environment; Large production capacity, annual output 0.5~ 500,000 tons.
