Cement Grinding Station application in mine industry, cement plant, large coal processing enterprises and Industrial crushing and grinding.
Cement grinding station, or called cement grinding plant, is an individual cement grinding unit formed independently from the final product stage of cement production. Cement Grinding Station processing stage will add the cement clinker into the appropriate amount of mixed materials for grinding, to produce the finished cement.
After gypsum, clinker, and limestone are measured by the belt weigher, they will be mixed together in accordance with particular proportions, and then sent to the stable weighing warehouse. During this process, magnetic metals are removed by the iron remover from these materials. Then mixed materials will be sent into the vertical cement mill for grinding. After grounding, the coarse powder will be sent back to the grinding mill while the qualified material will be sent to the elevator for finished products. Finally, they will be sent to finished product storage.
CHAENG was founded in 1958, has rich experience in cement plant and cement grinding plant construction, who can provide customers with the whole plant design, equipment supply, installation and commissioning supervision, etc one-stop services. If you want to know more information about the differences between cement grinding plant and full cement plant, you can contact with us directly.
1. High grinding efficiency
For the structure, of the cement mill, weadopts the advanced obstructing equipment for internal powder, add theactivated device to the fine grinding chamber, and there is the special grateplate at the end of the cement mill, which can reduce the size of the grindingmedium, greatly improve the grinding efficiency, and achieve the purpose ofhigh output and low energy consumption.
2. Energy saving and environmental protection
The cement grinding unit has advantages of simple structure,strong controllability, and easy to operate or maintain. The dischargeconcentration is less than 50mg/Nm3, lower than the discharge standard, andprotect the environment of the production site effectively.
3. Good quality of finished products
The production process overcomes the disadvantages of traditionalequipment. The fineness of product is easy to be adjusted, apply for differentrequirement of fineness. The equipment also has advantages of large heatdissipation area and low temperature inside mill. The finished product ofnew-type cement grinding unit has high quality and large capacity.
4. High output, large handling capacity
Compared to other production process, with samefeeding size and other working conditions, our cement grinding unit canincrease capacity by 30%, and the energy consumption can be reduced by 15%.
CHAENG can provide a variety of schemes for cement grinding, and make a choice according to the actual situation and needs of customers:
| Items | Scheme I Closed-circuit ball mill system | Scheme II Combined grinding system | Scheme III Vertical roller mill finish-grinding system | |
|---|---|---|---|---|
| Cement types | P·O42.5 | P·O42.5 | P·O42.5 | |
| Cement ratio, % | Clinker | 90 | 90 | 90 |
| Limestone | 5 | 5 | 5 | |
| Plaster | 5 | 5 | 5 | |
| Cement specific surface area, cm²/g | 3500 | 3500 | 3500 | |
| System output, t/h | 170 | 160 | 160 | |
| System power, kWh/t | 41 | 33 | 28 | |
| Annual electricity savings (×10,000 yuan) | — | 400 | 700 | |
| Metal wear, g/t | 50 (Steel ball) | 30 (Steel ball+roller surface) | 5 (Grinding roller+grinding table) | |
| Drying capacity | Weak | Medium | Strong | |
| Economic benefit analysis: the economic benefit caused by the high running rate, power saving and operation maintenance cost of vertical mill system |
|---|
| If one ton of cement saves 4.5kwh/t power, one day produces 5000T cement, one year works 300 days, and electricity cost is 0.7 yuan per kilowatt hour, you can save electricity cost: ￥4,725,000 per year |
| The annual maintenance cost balance: ￥3,660,000 |
| Cement maintenance cost balance per ton: ￥45,000 |
| Total: ￥8430,000 |
