1500 Tons/Day Cement Processing Line

Description of 1500 Tons/Day Cement Processing Line:
Our 1500t/d cement processing line is a new type of dry process cement clinker production line. The φ3.5×54m 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 processing line, 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 φ15×50mMF 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, φ3.5×54m 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 65℃ higher than the ambient temperature.

5. Cement grinding:
This 1500t/d cement processing line has two φ3.5×13m 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.
