Cement in powder form can be changed from plasticity paste to hard stone-like body and can become a total cemented granular materials through physical and chemical processes after being mixed with water. So cement is a good mineral binder. Cement can be not only hardened in the air, but also better hardened in the water in which it will maintain and develop strength. So cement is kind of cementitious material which will be of stronger hardness in water. Cement mill is used for cement grinding. Cement crusher is applied for cement crushing. In cement production line you need to choose suitable raw material mill and cement crusher.
Cement Application in industry
Invention of cement provides a material basis for the development of construction. From land engineering to water, underground engineering, cement plays an important role. Cement has been invented for a hundred years and it has always been the most widely used, the most consumed binder. In order to meet the different needs of construction, 200 kinds of cement have been developed. And the China cement mill is of growing kinds. The China cement mill varies from traditional ball mill to new European trapezium grinding mill. Cement crusher includes jaw crusher, cone crusher, impact crusher, etc. In Cement making plant, cement grinding mill and cement crusher play a very important role. They can crush or grind the cement to required fineness for industry application.
According to the use of cement, it can be divided into general cement, special cement and other cements with some prominent performances, such as expansive cement, low heat cement, colored cement and white cement. Among these, the general cement is the main silicate cement for general construction work and the special cement is adapted to specific uses of cement, such as dam cement, oil well cement, masonry cement, etc. In all these products production, cement mill will be used.
Silicate cement is a kind of cement most common in application. In interior decoration, this type of cement is commonly used. In addition, white cement and colored cement is also used in the decoration.
Cement production process
The whole production process of cement is generally as follows:
Homogenizing- preparation of raw material - raw material homogenization - preheat decomposition - the burning of cement clinker - cement equipment (ball mill or vertical roller mill) - cement packaging
Among all these procedures, we will introduce to you the cement crusher process and cement machinery process in detail. The first step is for cement crusher.
Cement Crusher and homogenizing :
In cement production process, cement crusher is very important since most of the raw materials will have to be crushed before being used to process cement, such as limestone, clay, iron ore and coal, etc. Limestone is the largest amount of raw material during cement production. After limestone mining, limestone is generally of large size and high hardness. Therefore the limestone crushing is very important in the whole material crushing. Usually we choose jaw crusher for limestone crushing since jaw crusher is of easy principle, convenient maintainence and low cost. However, if the whole cement mining scale is of large size, we usually choose cone crusher or impact crusher to assit jaw crusher and to be secondary or tertiary cement crusher machine. Also cement conveyor is used to transport these materials to next procedure, such as vibrating cement screen to screen out required fineness. In some production sites, we use a whole mobile crusher to complete the whole cement crushing and screening production since the mobile crusher is equipped with jaw crusher, impact crusher or cone crusher, vibrating feeder, vibrating screen, etc.
In the cement grinding, grinding mill will be used to grind the cement clinker to appropriate size to increase the size of its hydration and accelerate hydration rate so that it can meet the cement paste setting and hardening requirements. There are many kinds of cement plants, such as ball mill, high pressure suspension grinding mill, coarse powder grinding mill, Raymond mill, vertical mill, etc. In the exact production site, we can choose suitable Cement making machine according to the exact requirement and material information. This procedure is almost the last process of cement production. So cement grinding will directly influence the products quality. The cement mill price will also be affected by these factors .
