High Efficiency HVM3700 Gypsum Vertical Mill For Quicklime Raw Meal Grinding

Product Specification

What is a gypsum mill?
The gypsum vertical grinding machine is an energy-saving grinding equipment that combines mature vertical grinding technology, successful experience at home and abroad, and our company's technological innovation and upgrading. It integrates crushing, drying, grinding, grading, and conveying, and can be widely used in industries such as cement, electricity, metallurgy, chemical, and non-metallic minerals. It focuses on three major fields: non-metallic minerals, coal powder, and slag.
The range of materials that can be applied: river pebble, granite, basalt, quartz, iron ore, Diabase, limestone, Calcite, dolomite, Baryte, talc, gypsum, 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.

Specifications And Technical Parameters Of HVM Gypsum Vertical Mill

What are the advantages of a vertical mill specifically designed for desulfurization gypsum powder production line equipment?

Gypsum powder is a non-metallic mineral with high market value, widely used in various fields such as construction, building materials, power plants, papermaking, paint, food, medicine, etc. Unlike natural gypsum, desulfurization gypsum powder, as an industrial solid waste, also has recycling value. By using desulfurization gypsum powder production line equipment, waste can be turned into treasure and value can be created. Vertical grinding machine is a specialized mill that helps bring greater value to the field of desulfurization gypsum.

1. Understand desulfurization gypsum and equipment together
At present, limestone gypsum method is the more mature desulfurization method for thermal power plant desulfurization technology. In order to improve the efficiency of flue gas desulfurization, the desulfurization technology requires higher Calcium oxide content and fineness in limestone powder used for desulfurization. With the expansion of the gypsum market, the price of gypsum powder is also constantly increasing, and the number of projects for grinding gypsum powder is not constantly increasing.

2. Understand the vertical mill and its advantages used in the desulfurization market
Vertical grinding equipment is one of the ideal grinding and processing equipment. Guilin mining machinery responds to the call for energy conservation and emission reduction, helping to achieve efficient grinding and processing in many markets such as coal mines, thermal power plants, limestone desulfurization, desulfurization gypsum and other solid waste, metallurgy, building materials, etc. The vertical mill integrates crushing, grinding, grading, drying, conveying, and powder collection, with high grinding efficiency, high production rate, low energy consumption, larger feed particle size, energy conservation, and emission reduction. It is currently a specialized grinding equipment in the field of dry powder production. Its advantages and characteristics can be summarized as follows:

(1) Environmental noise reduction
Vertical grinding equipment has low vibration, low noise, full negative pressure operation, and no dust leakage, making it a specialized equipment that is conducive to enhancing market competitiveness.
(2) Reliable performance
The grinding roller limit device can avoid vibration caused by material breakage. New grinding roller sealing device, with better sealing performance.
(3) High powder yield
High grinding efficiency and high single machine productivity.
(4) Energy saving
Low energy consumption, compared to ball mills, it is 40-50% lower in energy consumption.
(5) Strong drying power
It can directly blow hot air and has strong drying ability, without the need to purchase an additional dryer. The feed moisture can reach up to 15%.
(6) Low investment
The process flow is simple, the system equipment is few, the layout is compact, the floor area is small, and it can be arranged outdoors to reduce comprehensive costs.
(7) Automated operations
Adopting a PLC fully automatic control system for remote control and easier operation.
