Sieve Plate
Screen plate is situated in pulper machine. The stator and rotor are placed on the screen plate. Pulper has a rotor inside the machine that grinds and mixes the pulp evenly.
Screen plate work as a strainer that separates large, uncut particles from pulp to separate and collect them to other containers. The pulp is passed through the strainer for further procedure. Contaminants stay collected on screen plate and don't mix with the pulp. Screen plate works continuously into the water. Therefore, it has to be made by corrosion resistance material.
Screen plate is made of stainless steel as it has to work continuously in water. Screen plate is easy in installation and has a long life. Screen plate works efficiently into pulper and separates the contaminants from the pulp.

Good wear resistance: Because the screen plate of the pulper needs to withstand the impact and friction of waste paper and impurities for a long time in the work, it has good wear resistance and can ensure a long service life.
Reasonable sieve: The sieve size, shape and distribution of the sieve plate are carefully designed to ensure the effective screening of impurities in the waste paper, while ensuring the passage rate of the fiber.
Corrosion resistance
The screen plate of the pulper is usually made of corrosion-resistant materials, which can adapt to various waste paper treatment environments and prevent damage due to corrosion.
Easy to replace
The screen plate is usually removable design, easy to replace and repair, can reduce downtime and maintenance costs.
High efficiency
The design of the screen plate makes the pulper have high efficiency when dealing with waste paper, which can quickly complete the crushing and screening process and improve the overall efficiency of the production line.

Application
The Screen Plate is used in hydrapulper or D-pulper or Fiber Separator. Screen plate is situated in pulper machine. The stator and rotor are placed on the screen plate. Pulper has a rotor inside the machine that grinds and mixes the pulp evenly.
Paper Machine Grapple
The Grapple is used in the hydraulic pulper to remove various entanglement impurities in waste paper pulp, such as iron wire, rope, plastic, cotton yarn, etc. The machine has advantage of higher work efficiency, lower energy consumption, simple structure and easy to operate and maintain, etc.

Product Advantage
Enhanced Performance: Pulper grapples work in tandem with a ragger and rope cutter, aiding in the removal and cutting of pulp-bound contaminants for smoother processing.
Block-Free Design: The extended movement range of the cutter minimizes blockages, ensuring uninterrupted operation.
High Cutting Power: Double hydraulic cylinders provide ample cutting force, delivering efficient handling and cutting of contaminants.
Robust Structure: The grapple features four tines, a lifting ring base, an air supply system with a pneumatic triad, and a two-position, four-way magnetic exchange valve for seamless operation.
Simplified Maintenance: Cleaned air and atomized oil flow smoothly through the air cylinder, ensuring long-lasting and efficient operation.
