5000 Ton Dry Process Cement Plant

5000 Ton Dry Process Cement Plant


5000 Ton Dry Process Cement Plant

Our 5000 ton dry process cement plant is designed to reduce pollution and energy consumption. With exquisite designs, it is capable of saving energy in each main production process.

1. Raw material crushing and grinding
   The dry process cement production line includes a single stage hammer crusher for limestone crushing. The simplified production flow reduces electricity consumption.
   A vertical grinding mill is adopted for raw material grinding. As compared with conventional middle-discharging mill and air swept mill, the vertical mill reduces power consumption by 5-7kW×h/t.

2. Material preheating
   Our dry process cement plant is fitted with a five-stage cyclone preheater featuring low pressure loss design. The cyclone with large volute and short barrel design is additionally designed with a guide plate and a flow-regulator, so the system resistance is largely reduced. Comparing with traditional counterparts, this preheating system has its draught fan electricity consumption reduced by 15%-20%.

3. Clinker cooling
   A latest model of grate cooler is utilized for cement clinker cooling. The required airflow and discharged waste gas is reduced by 0.6-0.8Nm3/kg-cl, as compared with older version cooling equipment. The electricity consumption of cooling fan and exhaust fan can be reduced by 20%, respectively.

4. Pulverized coal preparation
   Our cement production line utilizes a vertical mill for coal pulverization. This ensures energy consumption reduction up to 11.0kW×h/t, when compared with traditional coal powder production system composed of the air swept ball mill, dynamic powder separator, and the air tank pulse bag filter.

5. Material delivering
   To maximally reduce power consumption, the dry process cement plant adopts energy efficient material conveyors with high efficiency. For instance, the bucket elevator for delivering material into the preheater, and raw mix conveying system can help reduce consumption by 2.5-3kW×h/t.

For the purpose of saving electricity, our cement making machine is designed to offer smoother and simplified production flow. It maximally avoids redundant material delivering, so as to minimize the conveying distance and height difference of materials. Thus, the power consumption for material delivering is largely reduced.

6. Others
   In addition to above, our dry process cement plant has enhanced measurement precision, improved system efficiency, and reduced fuel and raw material usage, due to following designs. Firstly, quality and precision measuring equipment is utilized in each key production process. Secondly, at each dust or waste gas outlet, there are reliable and efficient dust filters to make sure only dust-bearing gas conforming to related standards can be discharged. These ensure substantially reduced cement production cost.

As compared with conventional airlift pump method, the rubber belt type bucket elevator for feeding materials into kiln tail reduces cool-air intake by 70000m3/h. This effectively improves the thermal efficiency of preheater. The circulating water cooling system largely saves water usage, by offering circulating water utilization rate up to 95%. Aside from these, effective measures are adopted to reduce the heat loss of equipment and pipelines, and energy efficient equipment such as electric motors and draught fans are selected. In addition, our dry process cement plant adopts variable frequency control system for fans and pumps, as well as efficient and low consumption installations like transformer, contactor, and lighting fixtures. All these ensure remarkably reduced energy consumption.
