5000 Tons/Day New Type Dry Process Cement Production Line

Description
Pengfei 5000t/d dry process cement production line is excellent in saving energy. It adopts various high efficient cement equipment and devices. It is designed with a smooth and tight process flow.e try to reduce production process and save transport cost. High-accuracy measuring equipment is adopted to reduce raw fuel waste and product loss. This cement production line is eco-friendly.


Methods and Techniques in Saving Energy
1. We choose energy efficient cement equipment to save electricity cost. For example, we save about 2.5 to 3 kWh/t electricity per unit by using the bucket elevator to transport raw materials.
2. A stable dust collector is installed at every source of dust in the cement production line. It not only reduces air pollution and saves production cost.
3. Raw material grinding process adopts a vertical grinding system. It could save electricity by 5 to 7 kWh/t per unit raw material compared with traditional middle-discharging system and air swept system.
4. We use circulating water to cool cement equipment. The indirect utilization rate is about 95%.
5. Our company also makes efforts to reduce heat loss from pipes and device surface. We adopt energy efficient motors and electrical fans in the cement production line.
6. Pengfei adopts belt bucket elevator to feed materials into kiln tail. It reduces inlet cold air volume by 7000 m³/h compared with traditional airlift pumps. It helps increase the thermal efficiency of preheater.
7. We install VVVF electrical control devices on fans and pumps to reduce power consumption of this cement equipment. We also choose energy efficient transformers contactors and lamps.


Main Process Flow
1. Limestone Crushing and Raw Material Grinding.
In this 5000t/d dry process cement production line, Single-stage hammer crusher is used to crush limestone. It makes this process quite simple.
2. Raw Material Preheating.
The five-stage cyclone pre-heater has a low-pressure-loss technical design. It features large volute and short cylinder. Deflectors and rectifiers are also installed in this cement equipment to reduce systemic resistance. Compared with traditional preheaters, it reduces power consumption by 15-20%.
3. Burning and Clinker Cooling.
In this dry process cement production line, we use grate cooler to cool clinker. Compared with the second generation grate cooler, it reduces necessary air volume and extra waste gas volume reduced by 0.6-0.8Nm³/kg-cl. Electricity consumptions of cooling fan and waste gas exhaust fan can be therefore reduced by over 20%.
4. Coal Dust Preparation.
This cement equipment adopts vertical mill for coal dust preparation. It could save energy by about 11.0 kWh/t per unit compared with the traditional cement process low of air swept ball mill, dynamic coarse powder separator and high concentration air tank pulse bag dust collector.
