Raw Materials and Equipments
Raw Materials
Limestone: Common forms of calcium carbonate used as raw material for cement manufacturing are 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. Only the purest varieties of limestone are white.
The second important raw material for cement production is Clay. The main component of clay is formed by hydrous aluminum silicates. The chemical composition of clay may vary from those close to the pure clay, to that containing a significant amount of admixtures as iron hydroxide, iron sulfide, sand, calcium carbonate, etc. Clay is used as an argillaceous component of raw mix.
Gypsum is the raw material commonly used in construction, building
materials, chemical industry, metallurgy, coating, and other industrial fields
Gypsum plays a very important role in controlling the rate of hardening of the
cement. Gypsum (hydrated calcium sulphate caso4.2h2o) 85 to 95 %
chemical-phosphor gypsum natural gypsum for agriculture and industrial use

CRUSHERS
Jaw Crushers
​
Production Capacity : 1-200t/h
Feeding Size: 125-1200mm
Application: Pebble, calcite, granite, quartz,
Concrete, dolomite, bluestone, Iron ore ,
Limestone construction waste .
The jaw crusher is suitable for crushing various ores or rocks with a compressive strength limit below 250 MPa. Widely apply for mining, cement and concrete industries. It is mainly used as coarse crusher and medium crusher in mines, building materials and infrastructure. The jaw cement crusher produced by Tuff brand has the characteristics of simple structure, easy manufacture, reliable operation, long service life and convenient maintenance
Cone Crusher
Production Capacity : 12-1, 814mᵌ/H
Feeding Size: ≤350mm
Application: Cobble granite , Basalt, iron
Ore, Limestone, quartz stone , diabase , gold
Ore and copper ore.
Raw materials of the cement plant are mostly from open-pit mines, and the ore size of large mines can reach 1.5-1.8m. In the preparation of cement raw materials, we first need to crush limestone, gypsum, clay and other materials into proper size to facilitate the subsequent transportation and storage, at the same time make full preparations for the next process (cement raw materials grinding). Therefore, as the first process of cement production, material crushing is particularly important in the design of a cement plant.
Hammer Crusher
Production Capacity : 5-600m³/h
Feeding Size : ≤314mm
Application : Coal, Salt, Gypsum,
alums, Brick, Tile, Limestone

Application:
river gravel, granite, basalt,
iron ore, limestone, quartz stone, coal gangue,
dolomite, feldspar, calcite, talc, barite
and building wastes, etc.

The impact crusher is a new and high-efficient cement crusher, with advantages of small size, simple structure, and large reduction ratio, less energy consumption, uniform practical size and flexible selectivity. The remarkable features of impact crusher is large feeding mouth, impact crusher own 1.5 times or even 2 times larger crushing cavity than that of other crushers.
