Durable Pulp Propeller Designed for Paper Machine Efficiency
The propeller in the paper machine equipment is the core component of the pulp circulation system. The main structure is made of 304/316 stainless steel, and it is equipped with a three-blade propeller or turbine impeller (with hard chromium plating on the surface to enhance wear resistance and corrosion resistance). The speed range of 200-320 revolutions per minute is achieved through variable frequency speed regulation. It can be adapted to slurry with a concentration of 3% to 7% and slurry tank volumes of 15 to 120 cubic meters. Its propeller propulsion design forms a three-dimensional circulation through axial and radial flow, ensuring uniform mixing of the slurry without sedimentation in the slurry tank. The propulsion efficiency is ≥95%, and it is equipped with a dual safety system of mechanical seal and packing seal, which not only meets the anti-corrosion and anti-rust requirements in high-humidity environments, It can also reduce energy consumption by optimizing the geometric parameters of the impeller, providing a stable and efficient pulp conveying solution for paper making enterprises.



Paper making machinery mesh cages (also known as circular mesh cages or forming mesh cages) are the core components of circular mesh paper machines, mainly used for pulp forming and dewatering. Their design directly affects the quality and output of paper. The cage is composed of a main shaft, a net frame, spokes and spacers. The spokes are evenly spaced and fitted onto the main shaft, and the net frame is installed on the spokes. According to the structure, it can be classified into common type, plate type, evacuated type, vacuum type, etc. According to the material, it can be divided into stainless steel, all-copper, etc. Among them, stainless steel mesh cages have become mainstream due to their advantages such as corrosion resistance, light weight and short maintenance cycle. Its structural stability, water filtration efficiency and corrosion resistance directly affect the quality of paper and production efficiency, and it is suitable for the production of various types of paper such as cultural paper, packaging paper and special paper.
Paper making machine rubber rollers are precision transmission and calendering equipment specially designed for paper making production lines. They are made of high-elasticity composite rubber materials through high-temperature vulcanization process in one piece. The surface is treated with laser micro-engraving technology to form uniform and fine diamond-shaped patterns, ensuring micron-level surface flatness control of paper at high speeds. The roller core is forged from high-strength alloy steel and has a dynamic balance accuracy of G2.5 grade after verification. It is equipped with a double-row tapered roller bearing structure, capable of withstanding over 30 tons of linear pressure without deformation. The rubber layer adopts a three-layer composite design: the outer layer is wear-resistant nano-particle reinforced silicone rubber, the middle layer is embedded with carbon fiber mesh to enhance tensile strength, and the inner layer is made of high-viscosity natural rubber vulcanized and bonded to the metal core shaft, ensuring no risk of delamination during long-term use. This rubber roller is specially designed with a spiral internal cooling water channel, combined with an intelligent temperature control system to achieve constant surface temperature control, effectively preventing paper wrinkling or uneven coating caused by high temperatures. Its modular design supports quick replacement and meets the production needs of all types of paper from cultural paper to specialty paper. Coupled with an Internet of Things monitoring system, it can provide real-time feedback on operating status, providing key equipment support for paper making enterprises to achieve 0.5mm thickness fluctuation control.
