Title Grinding equipment to promote the development of domestic ore processing industry
Description In order to improve the technological level of ore milling equipment for iron ore in China, we adopt new technology of multi break and little grinding, which is advanced in technology, obvious in energy saving and low in cost. When the feed size is reduced from 20mm to 12mm, the production capacity of the mill can be increased by 16%, and the process of "more crushing and less grinding" for the iron ore will be accelerated and the most modernized process will be taken. Iron ore crushing and grinding production process will generally be broken, medium, broken and fine broken three stages to break. The jaw crusher is the most widely used crusher, feed, product size uniform, and low operation cost; and fine crushing will adopt multi cylinder hydraulic cone crusher, through the thick broken, fine broken ore, the final product sieve into ore particle size of less than 12mm to mill in deep processing. China's iron ore grinding process has been relatively mature, like a small concentrator with a grinding process, but in recent years, a lot of concentrator by two section has three segments grinding instead of grinding, the grinding equipment is relatively small. The ore deep processing, an important link in engineering is dressing, dressing workshop will be purchased about 65% grade iron ore by magnetic separation, dehydration, drying, again produced a high concentrate powder, sintering agent, and then adding a certain amount of the resulting pellet for production of DRI, therefore in crushing and grinding the mineral part is very important, on the production of high granularity equipment and production material requirements.
