Shanghai Zenith Grinding Mill Solution: In the process of bentonite powder production, many customers will choose the LM Vertical mill, it is a simple and multifuctional mill with stable and powerful performance and compact layout.

Shanghai Zenith LM Vertical Roller Mill need Lower investment.

LM vertical mill integrates the advantages of grinding, conveying, Classifing and drying materials. Due to the multifunction of crushing, drying, grinding, classifying conveying in one, the LM Vertical Mill system is simpler with compacter layout, covers an area of about 50%-60% of the ball mill Line, and it can be arranged in the open air, so it can greatly reduce the overall investment cost.

Shanghai Zenith LM Vertical Roller Mill needs Low operating cost

(1) High efficiency: the roller directly rolls and grinds the material on the grinding disc, which has low energy consumption and saves 30% ~ 40% energy consumption compared with the ball grinding system.
(2) Less wear: the roller is not in direct contact with the grinding disc, and the roller and the lining plate are made of good quality materials such as high chrome steel. so the service life is longer and the wear is less.

Shanghai Zenith LM Vertical Roller Mill has high drying efficiency. Hot air from the outside into the mill, in the mill directly, many times full contact with the powder material, drying ability is strong, can save a dryer for the mill system, energy saving, by adjusting the temperature of hot air, can meet the requirements of materials with different humidity.

Shanghai Zenith LM Vertical Roller Mill is Easy to operate and maintain

(1) Equipped with automatic control system, can realize remote control, easy operation.
(2) equipped with a limit device to prevent direct contact between the roller sleeve and the grinding plate liner, to avoid destructive impact and violent vibration.
(3) By overhauling the cylinder, turning over the arm, replacing the roller sleeve and liner, it is convenient and fast to reduce the loss of shutdown.

Shanghai Zenith LM Vertical Roller Mill need has Stable product quality

(1) Because the material stays in the mill for a short time, it is easy to detect and control the product particle size and chemical composition, reduce repeated grinding and stabilize the product quality.
(2) the iron content in the product is very little, and the iron contained in the mechanical wear is easy to remove, used for grinding white or transparent materials, the whiteness and clarity of the product is high.

Shanghai Zenith LM Vertical Roller Mill is Environmental Friendly and clean

Small vibration, low noise, and the overall sealing of the equipment, the system works under negative pressure, no dust spillover, clean environment, meet the national environmental protection requirements
