High Efficient Mining Limestone Vertical Powder Calcium Quartz Stone Dolomite Grinding Mill
Description
Dolomite is a common carbonate mineral, which is widely used in various fields of national industrial production. In the field of metallurgy and chemical industry, dolomite is a good basic refractory material and a solvent for blast furnace ironmaking. In the field of agriculture, dolomite is an excellent raw material for the production of calcium magnesium phosphate fertilizer and magnesium sulfate. It is used in building materials, ceramics, environmental protection, energy saving and other fields. , Dolomite also plays an irreplaceable role.
【Scope of application】
The pulverizer can be widely used in metallurgy, chemical industry, power plant desulfurization, non-metallic ore pulverizing, pulverized coal preparation, rubber, paint, plastic, pigment, ink, building materials, medicine, food and other fields. The effect is remarkable and very popular.
【Applied materials】
For non-metallic minerals such as calcium carbonate, barite, calcite, gypsum, slag powder, manganese ore, coal, etc., it can be processed by ultra-fine grinding, and the product fineness adjustment is convenient and the operation is simple.
【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 ground 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.
