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 mil is used for cement grinding. Cement crusher is applied for cement crushing. In cement mining, you need to choose suitable cement grinding 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 needs of different construction, the increasing varieties of cement has reached more than 200 kinds. And the cement mill is of growing kinds.
The cement grinding mill varies from traditional ball mill to new european trapezium grinding mill. Cement crusher includes jaw crusher, cone crusher,impact crusher,etc. In cement mining,cement grinding mill and cement crusher play a very important role. They can crush or grind the cment to required fineness for industry application.
Cement crusher plant recommendation
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 an appropriate size to increase the size of its hydration, accelerate hydration rate so that it can meet the cement paste setting, hardening requirements. There are many kinds of cement grinding mill, 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 grinding mill 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.
Some ways to increase the cement grinding efficiency
1. To enhance the ventilation of mill to improve the surroundings of mills to enhance the ventilation of mill is the effective methods to increase the production capacity and to reduce the power consumption.
2. To adopt the new type scale board to improve the material of the mill parts
The new type easy grind ability spare parts is widely used now days for prolong the service life of parts and grinding media
3. To add grinding aid to increase the grinding efficiency
there have many kinds of grinding aid, most of them are organic surface-active material. Some research has shown the grinding aid of ethanol, butanol, butanol oil, and rolamine work out fine.
4. To reduce the temperature of cement to improve the quality of cement
High temperature will cause the dehydrate gypsum dewatering in cement processing, which will make cement false setting and material cementation.
