Product Description

50-3000tpd Cement Production Line Machine 

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.
8. Concrete Packaging.

Our 1500t/d cement plant for sale is a new type of dry process cement clinker production plant. The 3.5X54m rotary kiln has been used as rotary kiln, whose end is fitted with five-stage cyclone preheater and decomposition furnace.

 

Its process flow mainly consists of limestone crushing, raw meal grinding, raw meal homogenizing and storing, calcining, and cement grinding. Detailed information about it will be given in the following.

 

1. Limestone crushing: Limestone is crushed by the single-stage hammer crusher, which is usually used to crush medium-hardness brittle ores, like limestone, marl, shale, gypsum, coal, etc. It is capable of crushing large raw ores to the required feeding size, and its discharging grate can easily dispose the moisture and earth in ores. Special protection system is employed in iron feeding, which can send the uncrushed metals to the feeding device. In this way, the operator can stop the machine timely to solve the problem when they hear strange metal sound.

In this 1500t/d cement plant for sale, we use the TKPC16.18 single-stage hammer crusher. And its feeding size is 800mm, its production capacity 250t/h, and its annual utilization rate 25.51%.

 

2. Raw meal grinding: For raw meal grinding, we have HRM2800m vertical grinding mill system.

 

3. Raw meal homogenizing and storing: Our 15X50mMF homogenizing silo has integrated raw meal homogenizing and storing into one body, and its raw meal storage capacity is about 6500t and the storage period about 2.86 days.

 

4. Calcining: Its calcining system is mainly comprised of single-row five-stage CDC predecomposition system, 3.5X54m rotary kiln and new-type air girder cooling machine. Its productivity of cement clinker is about 1500t/d, and its heat consumption is about 840Kcal/kg (3511.0KJ/kg). The resolution ratio of calcium carbonate of the feeding materials is more than 90%. Additionally, the extra heat the waste gas is applied in drying raw materials and raw coal.

The clinker cooling has employed the advanced grate cooler with a grate bed that has an effective area of 61.8m2, and a clinker temperature that is 65c higher than the ambient temperature.

 

5. Cement grinding: This 1500t/d cement processing line has two3.5X13m tube mills and they are equipped with N-1500 type O-SEPA high-efficiency air powder separator to make up a circulatory grinding system. Their productivity is about 50t/h.
