High Efficiency Desulfurization Limestone Vertical Grinding Mill
Outstanding Advantages
Low Investment Cost
Because it integrates crushing, drying, grinding, and grading and conveying, the system is simple, the layout is compact, the floor area is small, and it can be arranged in the open air, so the investment cost can be greatly reduced.
Low Operating Cost
High efficiency: The grinding roller directly grinds and grinds the material on the grinding disc, and the energy consumption is low, which saves energy consumption compared with the ball milling system. Less wear and tear: The grinding roller does not directly contact the grinding disc during work, and the grinding roller and the lining plate are made of good materials, so the service life is long and the wear is less.
High Drying Efficiency
The hot air introduced into the mill from the outside is directly and repeatedly contacted with the powdery materials in the mill, and the drying capacity is strong, which can save a dryer and save energy for the mill system. By adjusting the temperature of the hot air, It can meet the requirements of different humidity materials.
Environmentally Friendly Cleaning
The vibration is small, the noise is low, and the equipment is sealed as a whole, the system works under negative pressure, no dust spills, the environment is clean, and it meets the national environmental protection requirements.
Adopt a new type of grinding device Automatic electronic control system
It integrates drying, grinding, powder selection and conveying
Specializing in the three major fields of non-metallic minerals, coal powder and slag powder

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 it passes through the annular groove 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.
