Process Description

CHAENG has advanced technology production equipment and a professional technical team. CHAENG holds deep domain knowledge of the industry and hence, is equipped to offer customized services that are directed to meet the needs of clients from cement plants.

The cement production line includes crushing and pre-homogenization, raw material preparation & homogenization, preheating & decomposition, cement clinker sintering, cement grinding, and packaging, etc. 

cement plant working process

 

1. Crushing and Pre blending
limestone, clay, iron ore, coal, etc. Limestone is the largest amount of raw materials in cement production. After mining, the size of limestone is large with high hardness, so limestone crushing plays a more important role in cement plants.
2. Raw material preparation
In the cement production line, producing 1 ton of Cement need to grind at least 3 tons of materials (including raw materials, fuel, clinker, mixed materials, and gypsum). Grinding operation consumes about 60% of total power in cement plants, raw material grinding more than 30%, while coal mill used in cement plants consumes 3%, cement grinding about 40%. So choosing the right grinding mills in the cement plant is very important. CHAENG can provide cement vertical mill, the specific surface areas of cement up to 3800 cm²/ g with stable and reliable quality, it can be saving electricity above 30% use of vertical roller mill production per ton cement clinker than traditional ball mill, and the power saving effect is very remarkable.
3. Raw materials homogenization
Adopting the technology of homogenization could rationally get the best homo-effect and afford an eligible production to the demand.
4. Preheating and precalcing
The preheater and calciner are the key equipment for precalcing production technique.
5. Burning cement clinker in a rotary kiln
The calcination of the rotary kiln is a key step of the cement plant, which makes directly influences on the quality of cement clinker.
6. Cement grinding
Grinding cement clinker (and gelling agent, performance tuning materials, etc) is used to grind the cement to the appropriate size (in fineness, specific surface area, etc.), optimize cement grain grading, increase the hydration area and accelerate the hydration rate to meet the requirements of cement paste setting and hardening.

 

cement plant

CHAENG delivers reliable cement project execution for cement plants using advanced cement machinery. With the manufacturing of individual components of cement plants and with fabrication, installation & commissioning of the entire cement plants, CHAENG has supplied & commissioned more than 150 Cement Plants.
