Recently, an Indonesian company acquired the coking coal assets of an Australian coal company for US$380 million. In the subsequent processing of coking coal, the LM vertical mill grinds coking coal acquired in Indonesia, which made the coking coal pulverization production greatly increased, and the LM vertical mill was unanimously recognized by everyone.
Coking coal is a commonly used raw material in industrial production, mainly used for blast furnace ironmaking and blast furnace smelting for copper, lead, zinc, titanium, antimony, mercury and other non-ferrous metals, in recent years Indonesia has also been one of the major exporters of coking coal, which means that the coking coal market still has great investment prospects. Coking coal pulverization to obtain high yield, it is necessary to choose the right grinding equipment, indonesia used LM vertical mill is a very authoritative one. The equipment set crushing, drying, grinding, grading, transportation in one, widely used in sand and gravel yard, concrete mixing station, dry mortar, power plant desulfurization, quartz sand and other industries, the following specific analysis of the working principle.
In the work, the motor drives the grinding disc to rotate, the hot air enters the vertical mill body from the air inlet, the material falls in the middle of the grinding disc from the unloading port, under the action of centrifugal force, the material moves evenly from the middle of the grinding disc to the edge, and when it passes through the grinding roller area on the grinding plate, it is crushed by the grinding roller, and the large piece of material is directly crushed, and the fine-grained material is squeezed to form a feed bed for intergrandular crushing. The crushed material continues to move to the edge of the grinding disc until it is taken away by the strong air flow at the wind ring, and the larger particle material falls back to the grinding disc to continue to crush, when the material in the air flow passes through the upper separator, under the action of the rotor blade, the coarse particles return to the grinding plate, and the qualified fine powder is milled with the air flow, collected by the system powder collector, and the powder that is collected is the product of the vertical mill grinding. When the iron block and other debris mixed into the material move with the material to the edge of the grinding disc, due to its own weight, it cannot be blown up by the wind, and the scraper plate installed at the bottom of the grinding disc is scraped into the slag discharge port outside the machine.
The LM vertical mill grinds coking coal acquired in Indonesia and can produce high-grade and high-quality pulverized coal for use in more industries. If you are interested in the device, please leave a message below.
