CHAENG have advanced technology production equipment and a professional technical team. CHAENG holds deep domain knowledge of the industry and hence, is equipped to offer customized service that are directed to meet the needs of clients from cement plants.
Cement production line includes crushing and pre-homogenization, raw material preparation & homogenization, preheating & decomposition, cement clinker sintering, cement grinding and packaging etc. CHAENG have the ability to built 300t / d ~ 3000 t /d cement production line independently, And has extensive experience in the design and construction, built many large cement production line
1. Crushing and Preblending
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 the limestone crushing plays a more important role in cement plant.
2. Raw material preparation
In the cement production line, producing 1 ton of Cement need grind at least 3 tons of materials (including raw materials, fuel, clinker, mixed materials,gypsum).Grinding operation consumes about 60% of total power in cement plants, raw material grinding more than 30%, while coal mill used in cement plant consumes 3%, cement grinding about 40%. So choosing the right grinding mills in cement plant is very important.chaeng can provide cement vertical mill, chaeng cement vertical roller mill in the production of cement specific surface area 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 naterials 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
Preheater and calciner are key equipment for precalcing production technique.
5. Burning cement clinker in a rotary kiln
The calcination of rotary kiln is a key step of cement plant, which makes directly influence 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.
CHAENG delivers reliable cement project execution for cement plants using advance cement machinery. With the manufacturing of individual components of cement plants and with fabrication, installation & commissioning of entire cement plant, CHAENG has supplied & commissioned more than 150 Cement Plants. We execute turnkey cement projects for Cement Plants, Rotary Kiln Cement Plants, Shaft Kiln Cement Plants, Clinker Grinding Units, Slag Cement Grinding Units and Slag Grinding Project. For successful implementation of our turnkey cement projects, we conduct various types of project development studies, feasibility studies etc. These are followed by engineering, procurement & construction management (EPCM) services. We supervise the construction, commissioning along with offering start-up and post start-up services.
