The LM vertical coal mill is an energy-saving mill equipment combining mature vertical mill technology, foreign successful experience and technical innovation and upgrading of our company.It is a set of crushing, drying, grinding, classification, transport in one, can be widely used in cement, electricity, metallurgy, chemical industry, non-metal mining and other industries, and focus on non-metal mining, coal powder and slag three field.
Low investment cost
Due to the combination of crushing, drying, grinding, grading and conveying, the system is simple, the layout is compact, the floor space is about 50% of the ball mill system, 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 the material on the grinding disc, which has low energy consumption and saves energy consumption by 30% to 40% compared with the ball mill system.
Less wear: Since the grinding roller does not directly contact the grinding disc during work, and the grinding roller and the lining plate are made of high-quality materials, then the service life is long and the wear is small.
High drying efficiency
The hot air that is introduced into the mill from the outside is directly and repeatedly contacted with the powdery material in the mill. The drying ability is strong, which can save a dryer for the mill system and save energy. It can meet the requirements of different humidity materials by adjusting the hot air temperature.
The vibration is small, the noise is low, and the equipment is sealed as a whole. The system works under negative pressure without dust overflow. The environment is clean and can meet the national environmental protection requirements.
Easy operation and maintenance
1. Equipped with automatic control system, which can realize remote control. Easy operation.
2. Equipped with a device to prevent direct contact between the roller sleeve and the disc liner, avoiding damaging shock and severe vibration.
3. It is convenient and quick to replace the roller sleeve and the lining plate by overhauling the oil cylinder and turning the rotating arm.The downtime loss is reduced.
Stable product quality
1. Due to the short residence time of the material in the mill, it is easy to detect and control the particle size and chemical composition of the product, reduce repeated grinding and stabilize product quality.
2. The product contains very little iron, and the mechanical wear iron contained in the product is easy to remove. When used to grind white or transparent materials, the product has high whiteness and clarity.
