Enter pizhou zhonglian witness grinding unit energy consumption of 23 degrees

Pizhou zhonglian cooperated with yancheng jedda in the technical transformation of the grinding link, and significant effect was obtained in the improvement of the performance of cement by the semi-finished grinding technology of roller press. At present, the average unit energy consumption of cement mill is about 33 degrees, and the backward level can be as high as more than 40 degrees. According to pizhou zhonglian, the biggest change in the renovation was the substantial reduction in the energy consumption per unit of the powder mill, which was only 21-23 degrees.

Pizhou zhonglian has made great progress in the power consumption. The installed power after the transformation was 460kW less than before the transformation, but the output of the platform was still maintained at 220-230 tons.

Cement grinding is the last step in making cement. In this link, the biggest production cost is undoubtedly the power consumption, accounting for about 90% of the total cost, reducing the power consumption of grinding will provide a huge help for cement enterprises to reduce the production cost.

It is learned that pizhou zhonglian currently its production of P.O42.5 cement clinker dosage from the technical change before 80% to 69%, fineness index dropped to 45 m screen more than 6% (P.O52.5 dropped to 2.5%), the specific surface area slightly increased, 3-32 m particle content of 70-75%.

Roller press without maintenance or cleaning for three years.

In the case of pizhou zhonglian system, the output and energy consumption can both be stable at the level before the technical change. Meanwhile, the 3d strength of cement has increased by 3Mpa, and the water consumption of standard consistency has decreased by 1% compared with that before the technical change. The rheological property of cement can be obviously improved. Because clinker dosage fell about 10 percent, its production cost fell significantly.

Hoist. In addition, according to pizhou zhonglian, the biggest change in the renovation was the substantial reduction in the energy consumption per unit of the powder mill, which was only 21-23 degrees.

Discharge bin. JD high efficiency fine powder separator is adopted in the roller press system to greatly improve the efficiency of powder selection. JD high efficiency fine powder separator in the end mill adopts the internal circulation process to replace the separation system of o-sepa with high energy consumption. Independent internal circulation of the air flow for powder selection is adopted.
