Generally speaking, paper machine downtime failures are divided into two categories. One is the production inherent failure downtime, and the other is the paper machine equipment downtime.The main reasons for the inherent shutdown of production are: in the process of using the wet end water filtrati

To play the paper machine, you must first get the headboxThe headbox has always been considered the heart of the paper machine and plays a decisive role in the quality of the paper. The headbox of a modern paper machine is very automated, but it is still necessary to know how it operates. This artic

The dryness of the wet paper out of the press section is generally only 30%~40%. In the new paper machine with compound press, the dryness is only 40%~50%. Therefore, it is necessary to use the drying cylinder to evaporate the water to make the paper dry. increased to 92%~95%.

Another online method is to screen the processing capacity. By reducing the thickened area at the bottom of the screen, the passing volume of the overall screen frame is increased (the heavy slag at the bottom of the screen has poor fluidity, and the area of the screen seam is seriously blocked). The side effect of this is that the processing load of the pressure screen system increases in the rear part, and it is necessary to optimize the processing capacity according to the slag-forming effect of the pressure screen two, three and the processing capacity. In order to alleviate the problem of heavy slag, many rotors are designed in a spiral or approximate spiral upward space shape, and an upward flow is formed during the rotation process of the rotor’s rotation inclination to partially offset the bottom enrichment effect.

In recent years, China's paper-making machinery industry has been faced with the continuous increase in the cost of paper-making equipment and raw materials at home, as well as the impact of foreign economic crises, as well as the dual pressure of exclusion and suppression of China's paper-making machinery industry.

Misleading properties of dehydration elements(1) PurityGiven this characteristic, it is often mistakenly assumed that many of the operational benefits are obtained from 100% pure ceramics. But in many cases, the opposite is true. The performance of engineering ceramics can be improved by utilizing c
