Background

Tungsten is an element with wide distribution, almost universally exists in various rocks, but the content of tungsten is low. The mineral deposit can be formed by enriching the relevant geological action to be mined as commercial ore. Tungsten ore, mainly scheelite, developed in foreign countries for a long time, accounts for 60% of the total production capacity. Although the proven reserves of 376 ten thousand of scheelite in China account for 71 percent of the total reserves of wolframite in the world, because the ore substances of large and ultra-large tungsten polymetallic ore beds are complex in components, the embedded granularity is fine, and the dressing and smelting technology is not thoroughly solved, the quartz vein type wolframite is mainly mined at the present stage and accounts for 90 percent of the mined ore quantity in China.

After the tungsten ore is mined, multiple processing is required to be carried out on the tungsten ore, the pulverization is one necessary process, the tungsten ore is pulverized to obtain fine particles, then the tungsten ore is made into tungsten powder, the tungsten powder has certain requirements on impurity content, and the oxygen content is controlled within a certain range. The particle size of the tungsten powder is usually 2-10 μm. The tungsten powder is in the shape of polygonal particles. Further, the specific surface, bulk density, tap density, etc. of the tungsten powder also vary within a certain range. The properties of the tungsten powder have direct influence on the production of tungsten materials and the quality of tungsten powder metallurgy products, and particularly the influence on purity and granularity is more obvious. Tungsten powders are classified according to purity and particle size and different uses.

Need use breaker in the tungsten powder production process, carry out the secondary crushing with the tungsten ore granule through breaker and obtain more tiny granule, but present breaker can not accomplish the product of output and accord with the requirement completely when the breakage, often can mix with some great granules of volume in its output product, leads to the garrulous granule granularity size of tungsten ore not to accord with the requirement.
