Large Output 80 t / h Limestone Powder Vertical Mill Mining Machinery Cement Plant Equipment

Description

HVM vertical pulverizer is designed and developed on the basis of widely absorbing the advanced technology of various vertical pulverizers at home and abroad and drawing on a lot of engineering application experience. The comprehensive large-scale grinding equipment with five functions in one, has many characteristics such as centralized process flow, small footprint, low investment, high efficiency, energy saving, environmental protection and so on.

【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.

【Vertical Mill Application】
Non-metallic mineral grinding: It is applicable to industrial milling fields such as limestone, lime, barite, talc, gypsum, cement raw material, slag, cement, etc.

【Technical Advantages】
1. Large output and high work efficiency, all accessories are independently produced by Tongli Heavy Machinery.

2. The grinding roller bearing adopts the thin oil circulating lubrication method, which can ensure that the bearing works at a lower temperature, and at the same time, the quality and purity of the lubricating oil can be controlled, which is beneficial to prolong the service life of the bearing.

3. The combined powder separator has high powder selection efficiency, and is equipped with a roller turning device, which can turn the grinding roller out of the mill for easy maintenance.

4. Compared with some other forms of roller mills, the hydraulic system of the vertical mill has low operating pressure, low oil leakage failure rate, and high safety and reliability.
