Description of Environmental Protection Equipment

 Our environmental protection equipment is typically designed to separate solid granules from air or liquid in metallurgy industry, electricity field, chemical industry, building material sector, etc.   It is mainly comprised of dust hopper, filtration chamber, air cleaning room, holder, lift valve, dust cleaning device.   The workflow of this environmental protection equipment is as follows: Dusty gas enters into the dust hopper through the air duct, and then large-particle dust is left at the bottom of the hopper while the small-particle dust is brought by the air flow to the filtration chamber where granules remain on the outside surface of the filtration bags and the purified air enters into the bags. Finally, purified air is discharged by the exhaust outlet via bag mouths and cleaning room.

Performance Features of Environmental Protection Equipment

1. High dust collecting efficiency: the dust concentration of purified air is no more than 50mg/Nm3, and its dust collecting efficiency is more than 99.9%.  

2. High automation degree: automatic microcomputer control technology has been employed for cleaning dust in chambers, automatically unloading and discharging dust.  

3. Advanced technology: developed on the basis of dust collection technology in America and Germany, our environmental protection equipment is capable of reverse blowing in different chambers and pulse injection blowing. The reverse blowing helps to avoid insufficient kinetic energy, and the pulse injection blowing is able to prevent the filtering and dust cleaning from simultaneously proceeding, as a result of which this machine has high adaptability as well as high dust collecting efficiency.  

4. High operating efficiency: its maintenance can be made without need to stop the machine, which is quite easy and convenient. If working with the main motor, the environmental protection equipment can have a 100% operating efficiency.  

5. Long service life: high-quality pulse valve have been applied to ensure its high-efficiency and stable performance. When matched with quality needle felt filter materials, the filter bags can have an average working life of two years.  

6. Strong applicability: it can be used to deal with dusty air with an inlet concentration as high as 1300mg/Nm3. Besides used individually as dust collecting device for air purification, it is also can work together with high-efficient powder classifier and vertical grinder. When fitted with needle felt or other special filter materials, this environmental protection equipment can be used to handle a wide range of dusts. When designed with antistatic filter materials, it is capable of high-concentration coal dust.  

7. It is capable of handling large air volume, and has the advantages of good dust removing capacity, high dust collecting efficiency, reliable operation, easy and convenient maintenance, small size, and so on.

Process of cement production line

 

1.Raw Materials 
The main raw materials used in the cement manufacturing process are limestone, sand, shale, clay, and iron ore. The main material, limestone, is usually mined on site while the other minor materials may be mined either on site or in nearby quarries. Another source of raw materials is industrial by-products. The use of by-product materials to replace natural raw materials is a key element in achieving sustainable development.
 
2.Raw Material Preparation 
Mining of limestone requires the use of drilling and blasting techniques. The blasting techniques use the latest technology to insure vibration, dust, and noise emissions are kept at a minimum. Blasting produces materials in a wide range of sizes from approximately 1.5 meters in diameter to small particles less than a few millimeters in diameter. 
Material is loaded at the blasting face into trucks for transportation to the crushing plant. Through a series of crushers and screens, the limestone is reduced to a size less than 100 mm and stored until required. 
Depending on size, the minor materials (sand, shale, clay, and iron ore) may or may not be crushed before being stored in separate areas until required.

 

3. Crushing and Pre-homogenization.
Crushing. During producing Concrete, most of the raw materials must be first crushed before being used to make concrete. Among these raw materials which include lime stone, clay, iron ore and coal, etc. the lime stone is of the greatest usage to make concrete. With comparatively larger particles and higher hardness, crushing the lime stone to required fineness after mining is of relatively important consequence among crushing all those raw materials. There are many crushers used in crushing these raw materials, such as jaw crusher, impact crusher, cone crusher and vertical shaft impact crusher, etc. According to the raw materials' different particles and hardness, there are several suitable crushers which can be used in the crushing.
Pre-homogenization of raw materials.

 

4. Raw material Homogenization.
In the process of new dry concrete production, the stability of pit entry clinker raw material component is the premise of the whole system. Raw material homogenization system plays very important role in the stability of pit entry clinker raw material component.

 

5. pre-heater and calciner

 

6. The burning of concrete clinker.

 

7. Grinding
Grinding is the last process of cement produce and also is the most current consuming working procedure. Cement clinker get grinded into the right size. The smaller the particle size is, the better the final cement is.It's important to choose suitable grinding machine.
