Cement is a hydraulic binder. Cement mixed with water, after a series of physical chemistry from the slurry into a hard rock plasticity on hardening conditions, the hardening of cement both in the air, but also better able to harden in the water, maintain and continue the development of its strength. So the ground work for the cement material can also be used for underground construction. Common on roads and bridges in the cement are: Portland cement, ordinary portland cement, slag cement, pozzolanic Portland cement, fly ash cement, Portland cement and composite cement six varieties. In addition, some special projects, also with high alumina cement, expansive cement, rapid hardening cement, still in the construction of Portland cement and Portland cement-based.

The extensive use of cement production to increase demand for cement, the cement process has also been demanding. Cement mill process to increase roll crusher has been widely used in modern cement. The process mainly slip material sieve material removal broken system, the process are: clinker, slag and gypsum materials went into a slide screen, slide screen material vibration in the motor eccentric block, the material less than 6mm Kuei Department into the cement vertical mill, greater than 6mm of material into the roll crusher all.

In order to avoid the emergence of on-site roll crusher problems affecting the normal cement vertical mill to generate, especially with a bypass pipe, slip material screen switches, and limit the use of electric control. Once the breaker problems, immediately slip material on screen, so the material into the bypass, while maintenance roller crusher, vertical mill to ensure the normal operation of the cement. Roll crusher in the production process considerations. In the roll crusher, require rod valve fully open, so that the maximum inlet, so that all the roller face even by force; take the bypass feed, ask the bar-type valve all closed, with particular attention prevent non-normal working hours crusher material into the crusher roller room; all the broken material after it stopped crusher, crushing machine can not boot otherwise.

Roll crusher to join the application, to a certain extent, the operation to protect the vertical mill for cement has a more comprehensive process improvement requirements, increased cement production, greater to meet different customer needs.
