The Lm Series Vertical Mill (rollcrusher) is suitable for crushing medium-hard materials such as limestone, slag, coke, coal and other materials in the industrial sectors such as cement, chemical, electric power, metallurgy, building materials and refractory materials. This series of roller crushers is mainly composed of roller, roller support bearing, pressing and adjusting device and driving device.

Cement is a hydraulic cementitious material. After mixing with water, the cement changes from a plastic slurry to a hard rock through a series of physical and chemical reactions. In terms of hardening conditions, the cement can harden in the air and also harden in the water, keep and continue. Develop its strength. Therefore, cement materials can be used for both underground engineering and underground engineering. Commonly used cement in roads and bridges are: Portland cement, ordinary Portland cement, slag Portland cement, volcanic ash Portland cement, fly ash Portland cement and composite cement.

In addition, in some special projects, high-alumina cement, expanded cement, fast-hardening cement, etc. are still used, and Portland cement and ordinary Portland cement are still the main projects in the construction. The wide use of cement has increased the demand for cement production and has high requirements for cement processes. The addition of roller crushers in cement grinding processes has been widely used in modern cement companies.

The process mainly adopts the sifting material screening dust removal and crushing system. The main process flow includes: clinker, slag and gypsum enter the sifting screen together, and the sifting screen is vibrated under the vibration of the motor eccentric block, and the material part of less than 6mm enters. Cement vertical grinding, all materials larger than 6mm enter the roller crusher.

In order to avoid the on-site problem of the roller crusher and affect the normal generation of the cement vertical mill, the bypass pipe, the slide screen switch and the electric limit control are adopted. Once there is a problem with the crusher, immediately open the slide screen to allow the material to enter the bypass and repair the roller crusher to ensure the normal operation of the cement vertical mill.
