Coal Mining Limestone Vertical Mill Pulveriser HVM1250

Energy Saving Mining Limestone Grinding With Vertical Roller Mill
 
 
Description
 

【Scope of Application】
calcium carbonate pulverization, gypsum powder processing, power plant desulfurization, non-metallic ore pulverizing, pulverized coal preparation, etc.

【Materials】
limestone, calcite, calcium carbonate, dolomite, barite, talc, gypsum, diabase, quartzite, bentonite, etc.

【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.

 
Technical Data

 Re:The data based on Mohs'hardness 3-4 material
Limestone Bond Index≤13kwh/t
 

【Characteristics】

1. High efficiency and energy saving: under the condition of the same fineness and motor power, the output is more than double that of jet mill, stirring mill and ball mill.
2. Long service life of wearing parts: The roller sleeve can be turned over for use, which prolongs the service life of wear-resistant materials.
3. High safety and reliability: because there are no rolling bearings and no screws in the grinding chamber, there is no problem that the bearings and their seals are easily damaged, and there is no problem that the screws are easy to loosen and damage the machine.
4. High product fineness: The fineness of grinding products can reach 325 meshes at one time.
5. Environmental protection and cleanliness: The pulse dust collector is used to capture dust, and the muffler is used to reduce noise, which has the characteristics of environmental protection and cleanliness.
