Rubber /Grooved Press Roll
Rubber /Grooved Press Roll
Max Working Speed : 2000m/min Maximum Diameter: 1600mm Maximum Face Length: 14000mm
Rubber Press Roll is more important to provide good elasticity and ease the pressing effect of the upper press roll on the wet paper and felt, thereby prolonging the service life of the felt and reducing the “compression” of the wet paper.
The elastic encapsulated lower roller can also give the 2 rollers good contact and uniform dehydration effects, and compensate for the high error of the lower pressure roller.
The rubber hardness of the rubber roller in the production of general paper is usually 70 to 90 Shore hardness. Rubber rollers used for each press in the press section.
Jumbo rubber press roll
Jumbo rubber Press Roll /Blind drill Jumbo Press Roll
Max Working Speed : 2200m/min Maximum Diameter: 1600mm Maximum Face Length: 120000mm
Jumbo Press roll usually refers to a nip composed of pressing rollers which a diameter of more than 1000mm. It is often used in the production of corrugated paper, cardboard, and other paper or cardboard with large basis weight.
Compared with ordinary presses, it has a wide nip formed by the large-spoke press, the paper sheet can be pressed for a long time in the nip. It can improve the dehydration efficiency, increases the de-watering capacity and paper quantity because of the two-way vertical dehydration design.At the same time, it can also reduce steam consumption in the dryer section and further reduces production costs. The strength and burst resistance of the paper also been improved.
Normally, the paper machine adopts this technology has the feature of high speed, low energy consumption, and good paper quality. Therefore, jumbo pressing technology and equipment have become the first choice in the speed-up and energy-saving of old paper machines and the design of new paper machines.
Vacuum suction press roll
Vacuum Suction Press Roll
Max Working Speed : 2000m/min Maximum Diameter: 1300mm Maximum Face Length: 10000mm
Vacuum suction press roll is mostly used in medium and high speed paper machines.
The function of the vacuum chamber is only to suck the air in the shell holes. The thicker the roll shell, the more air volume is sucked. Therefore, the use of high-strength metal to make a vacuum suction press roll with a thin roll shell is beneficial to improve the efficiency of press dehydration. The vacuum pressure roller shell is covered with rubber with a thickness of 30-40mm. The advantage of encapsulation is to make the pressure distribution uniform, reduce the abrasion of the felt, and increase the pressure of the press line. Production practice shows that the axial and circumferential center distance of the holes on the vacuum pressure roller is smaller, and the number of holes is larger, which can significantly improve the dehydration effect of the vacuum pressure roller, thereby effectively eliminating the embossing phenomenon and extending the service life of the felt.
Suction Touch/felt/pickup roll
Suction Touch Roll / Couch Roll / Wire Xihu (West Lake) Dis. Roll / Drive Wire Roll /Pickup Roll/ Breast Roll

Can you explain the impact of guide rollers on the overall efficiency of material handling systems?
Guide rollers play a significant role in the overall efficiency of material handling systems. Here’s a detailed explanation of their impact:
- Precise Material Movement:
Guide rollers are designed to guide and support the movement of materials along a desired path. By providing a stable and controlled surface for material conveyance, guide rollers ensure precise movement and positioning. This precision minimizes the risk of material deviation, misalignment, or collisions, allowing for smooth and efficient material flow within the system. Accurate material movement enables efficient processing, reduces downtime, and enhances overall productivity.
- Reduced Friction and Energy Consumption:
Well-designed guide rollers with low-friction surfaces can significantly reduce the amount of energy required for material handling. By minimizing friction between the guide rollers and the conveyed materials, less power is needed to move the materials along the desired path. This reduction in energy consumption leads to improved energy efficiency and lower operational costs. Additionally, reduced friction helps extend the service life of the guide rollers by minimizing wear and heat generation.
- Enhanced System Throughput:
Efficient guide rollers contribute to increased system throughput in material handling operations. By facilitating smooth and consistent material flow, guide rollers help eliminate bottlenecks and optimize the overall speed and capacity of the system. When materials can be conveyed quickly and reliably, the system can handle higher volumes of materials, leading to improved productivity and throughput. Guide rollers also enable efficient sorting, merging, or diverting of materials, further enhancing system throughput and flexibility.
- Improved Product Quality:
The use of guide rollers in material handling systems helps maintain product quality and integrity. By guiding materials along a predetermined path, guide rollers prevent material damage, deformation, or contamination that can occur due to uncontrolled movement or collisions. This results in better product quality and reduces the risk of rework or product rejection. Guide rollers also ensure consistent material positioning, which is crucial for precision operations such as assembly, packaging, or quality control.
- Minimized Downtime and Maintenance:
Efficient guide rollers can contribute to reduced downtime and maintenance requirements in material handling systems. When guide rollers are properly designed, installed, and maintained, they operate smoothly and reliably, minimizing the risk of failures or disruptions. High-quality guide rollers with durable materials and components can withstand the demands of continuous operation and heavy loads, reducing the need for frequent replacements or repairs. This leads to increased system uptime, reduced maintenance costs, and improved overall equipment effectiveness (OEE).
- Worker Safety and Ergonomics:
Guide rollers contribute to a safer and more ergonomic working environment in material handling systems. By guiding materials along a predetermined path, guide rollers help prevent material spillage, which can create tripping hazards or pose risks to workers. Additionally, guide rollers facilitate smooth and controlled material movement, reducing the physical strain on workers during manual material handling tasks. This promotes a safer and more comfortable workplace, minimizing the risk of injuries and improving overall worker productivity.
In summary, guide rollers have a significant impact on the overall efficiency of material handling systems. They enable precise material movement, reduce friction and energy consumption, enhance system throughput, improve product quality, minimize downtime and maintenance, and contribute to worker safety and ergonomics. By selecting and maintaining high-quality guide rollers, material handling operations can achieve optimal efficiency, productivity, and cost-effectiveness.
