When the line speed of the paper machine is low, one generation of paper products should be considered, and the width of the paper is not large. However, internal combustion engine oil, hydraulic oil or gear oil cannot be used to replace the circulating oil of the paper machine dry. Due to the low t

Dehydration element selection principle?Wear resistance:The wear properties of a material determine how long it can maintain the correct shape, such as the leading edge of the ceramic strip and the angle of inclination. The stable operation of the paper machine can only be provided with the performa

The rewinding of the toilet paper rewinding machine includes an upper rewinding roller, a lower rewinding roller, a rear rewinding roller and a pressing roller having the same linear speed as the rear rewinding roller, which is characterized in that the pressing roller is in the base paper. The rewi

The paper cutter is the standard supporting mechanical equipment of the printing factory, which is mainly used to deal with the paper cutting requirements in the pre-printing and post-printing stages. The paper cutter has developed from the original mechanical paper cutter to the tape control room paper cutter, and then to the microcomputer program control, color display, full image operation guidance visual processing and computer-aided cutting. External programming and editing of production data cutting The system makes the paper cutter shorter production preparation time, higher cutting accuracy, lower labor intensity, and better operational safety.

In the screw conveyors used in metallurgy, mining, chemical and other industries, the shaft end gland is widely used for packing sealing. Since the particle size of pulverized coal is 200 mesh, it belongs to fine powder and has certain fluidity. Therefore, due to the poor sealing of the shaft end of

According to the different wire structure of papermaking pulping equipment, papermaking and pulping equipment can be divided into: Fourdrinier wire type, rotary wire type, sandwich wire type, stacked wire type and facing rolls. Paper pulping equipment can be regarded as a linkage composed of multiple equipments. Usually it can be divided into two parts: wet part and dry part. The wet end includes the stock flow equipment, the wire section and the press section; the dry end includes the dryer section, calenders and reels.
