Raw materials employed in the manufacture of cement are extracted by quarrying in the case ofhard rockssuch aslimestones,slates, and someshales, with theaid of blastingwhen necessary. Some deposits are mined by underground methods.Softer rockssuch aschalkandclay…
Wet magnetic separator is usually used for sorting the fine-grained strong magnetic minerals, or removing strong magnetic minerals from non-magnetic minerals.
Chinaware ball mill is mainly used for the mixing and grinding of materials, and the fineness of the final products is even, thus saving motive power. It can be used in both dry grinding and wet grinding.
Vibratory feeder in the production line can transport the material with the shape of massive and particles smoothly to the feeding device in a stable time.
The dryer machine has been mainly used for drying materials with some humidity and granularity in the fields, such as ore dressing, building materials, metallurgy, chemical industry, etc.
Spiral separators, which are also called spiral concentrators, are gravity devices that separate minerals of different specific gravity according to their relative movement in response to gravity, centrifugal force and other forces in the fluid medium.
Roll crusher is a crushing machine researched and manufactured by our company for coarse crushing.

Lime Component Limestone: Common forms of calcium carbonate used asraw material for cement manufacturingare limestone and chalk.Limestone is of predominantly fine grained crystalline structure, its hardness is between 1.8 to 3.0 of the Mohs scale of hardness and specific gravity 2. To 2.8. Limestone usually contains admixtures of clay substance or iron compounds, which influences its color.

Chalk is soft raw material, it does not require crushing. Marl is a limestone with admixtures of silex and clay substances, as well as iron oxide.It is a transitional stage to clay. The hardness of marl is lower than the hardness of limestone The more clay substances, the lower its hardness. This is an excellent raw material for cement production.
