High Output Fineness Up To 2000 Mesh Lime For Calcite Mill Plant
Description
Calcite Ultrafine Mill
【Scope of application】
Calcium carbonate crushing processing, gypsum powder processing, power plant desulfurization, non-metallic ore pulverizing, coal powder preparation, etc.
【Material】
limestone, calcite, calcium carbonate, barite, talc, gypsum, diabase, quartzite, bentonite, etc.
【Features】
Ultrafine mill (also called calcite micropowder mill, limestone micropowder mill, calcium carbonate micropowder mill, talc micropowder mill, barite micropowder mill, gypsum micropowder mill, marble micropowder mill, feldspar micropowder mill, Fluorite micro-powder mill) is mainly suitable for ultra-fine powder processing of non-flammable and explosive brittle materials with medium and low hardness and Mohs hardness ≤6. The output can reach 0.4-45 tons per hour.

Re:The data based on Mohs'hardness 3-4 material
The product fineness can reach 10 um(1250 mesh)
【Performance Advantage】
Energy efficient
Under the condition of the same finished product fineness and motor power, the output is more than double that of jet mill, stirring mill and ball mill.
Long service life of wearing parts
Grinding rollers and grinding rings are forged with special materials, which greatly improves the utilization. Generally, it can last for more than one year. When processing calcium carbonate and calcite, the service life can reach 2-5 years.
High safety and reliability
Because there is no rolling bearing and no screw in the grinding chamber, there is no problem that the bearing and its seals are easily damaged, and there is no problem that the screw is easy to loosen and damage the machine.
Environmentally friendly and clean
The pulse dust collector is used to capture dust, and the muffler is used to reduce noise, which is environmentally friendly and clean.
【Working Principle】
The motor drives the grinding disc to rotate through the reducer, the material falls into the center of the grinding disc from the feed inlet, and the hot air enters the mill from the air inlet. Under the action of centrifugal force, the material moves to the edge of the grinding disc, and is crushed by the grinding roller when passing through the annular groove on the grinding disc. The crushed material is carried by the high-speed airflow at the air ring at the edge of the grinding disc, and the large particles fall directly on the grinding disc. Re-grinding, when the material in the airflow passes through the dynamic and static separator, under the action of the rotating rotor, the coarse powder falls on the grinding disc for re-grinding, and the qualified fine powder is milled together with the airflow and collected in the powder collecting device, which is product. Moisture-containing materials are dried during contact with hot gas to achieve the required product moisture.
