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. Quarry crusher is applied for cement crushing. In cement mining, you need to choose suitable cement grinding mill and cement crusher.
Cement industry, the rock block with a large volume of mineral particles mixed, easy to scattered and fragmentary features. One of the main material for the sandstone and shale. Sandstone and shale, sandstone and shale is a range of precipitation between the rocks. The density of 0.8 ~ 1.5t/m3, compressive strength of 160MPa, amounted to 10-15% silicon, the material due to its high hardness and high abrasion resistance, and the high cost of Cone Crusher comparison, we use stone crusher; limestone, when it amounted to 6-7% carbon, due to high hardness, with the single-stage hammer crusher, hammer loss of large, can only be broken nearly 20 million tons, representing a counter-type crusher broken materials, production fell by nearly half, inefficient, therefore, for low-quality limestone, we choose impact crusher.
