1. Advanced Technology Brings Lower Power Consumption.
Compared with traditional cement production line, the 300 t/d cement plant designed by Chaeng uses lower energy consumption equipment in the main part of energy consumption, such asvertical raw mill, vertical coal mill, vertical cement mill, etc., and the energy saving effect is very significant, which can reduce energy consumption with an average of 15-20 kWh/t.
2. Reasonable Design, Reduces Dust and Noise Effectively
Cement production has always been one of the leading causes of environmental pollution, thus more and more cement plant is looking for a solution to reduce noise and dust pollution. Chaeng fully considers the sustainable development in the design, reducing dust through campus greening, filter, etc. Since the introduction of noise control programs in key areas, the factory noise is lower than the national standard.
3. Shorter Delivery Time, Earlier Profits
With large supporting cast steel companies and large machining workshop, Chaeng has 120t casting ability and can supply complete spare parts. Furthermore, with a variety of long-term cooperation and first-class equipment suppliers, it greatly shortens delivery cycle, and makes your profit in the shortest possible time.
CHAENG (Xinxiang Great Wall Machinery) has a history of more than 50 years and has accumulated rich experience in cement machinery. At present, we have been able to supply 300-5000 t/d cement EP project, providing solutions for the world’s growing demand for cement.
300 t/d cement production line designed by CHAENG Great Wall machinery, fully learns from the lessons and experiences of more than 20 years of NSP production line design, the general layout scheme, process layout, equipment selection, automatic control level, etc. and combines with today’s international advanced production concept to optimize design. It’s composed of raw materials preparation, raw meal grinding, raw meal homogenization, clinker burning, cement mill grinding, packaging, delivery and so on. The cement equipment in the production line include: raw materials vertical roller mill, vertical coal mill, cement rotary kiln, cement ball mill, cyclone preheater and grate cooler, etc.
Cement Manufacturing Process
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 rightgrinding 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 tube 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 production, which makes directly influence on the quality of cement clinker.
6. Cement grinding
Cement grinding 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.
