Description of LM verticalmill

SBM LM series vertical mill is an advanced grinding machine, adopting top-ranking technology home& abroad and is designed based on many years of manufacturing experience of grinding mill.

As a professional vertical mill manufacturer and vertical roller mill suppliers, we will supply the clients with vertical mill maintenance,vertical mill wear parts, vertical mill working principle, vertical mill operation,vertical mill technology specification etc.

SBM LM series vertical mill is an ideal machine that integrates crushing, drying, grinding, and grading conveying all together. This vertical roller mill is an ideal choice for be used as vertical coal mill,vertical gypsum mill,vertical cement mill and so on. We believe our vertical mill is better than loesche vertical mill.

SBM LM series vertical mill is widely used in such industries as cement making, power, metallurgy, chemical industry, non-metallic mineral. It is used to grind granular and powdered materials into powder with required fineness.

SBM LM series vertical grinding mill is the ideal substitute of the traditional grinding mills like Raymond grinding mills, high pressure suspension grinding mills, ball grinding mills, etc. and to be used as coal vertical mill,gypsum vertical mill,cement vertical mill and so on.

• Simple structure and easy to maintenance.
• Reliable performance, low operation cost.
• High crushing ratio and high drying ability.
• Low investment cost with stable quality.
• Environmental protection.

The motor drives the grinding table through decelerator. The materials fall down the center of grinding table from feed opening. At the same time, hot air comes into the mill from the air inlet. Due to the centrifugal force, materials move to the edge of the grinding table. The materials are pulverized by the roller when pass the groove on the grinding table. The crushed materials are brought up by vane high-speed airstream, the larger particles fall down to the grinding table for regrinding. When the materials in the airstream pass the separator fixed on the top of the grinding mill, the coarse powder fall down the grinding table for regrinding under the function of rotation rotor. The fine powder comes out with the airstream, and is gathered by the dust catcher. The materials content with moisture will be dried when they meet the hot airstream. Through adjusting the temperature of the hot airstream, it can meet different material’s requirement, and also through adjusting separator, it can reach proper fineness of materials.
