Conveying Solutions Across the Papermaking Industry

Author :


In the papermaking industry, the requirements for material characteristics, conveying environments, and equipment stability vary significantly across different production stages. Consequently, a variety of conveyor types must work in synergy. The following sections outline the commonly used conveying equipment and their respective advantages at each major stage.


I. Raw Material Preparation Stage

Common Equipment: Belt Conveyors, Bucket Elevators, En-masse Conveyors.

Advantages:

Belt Conveyors: Ideal for bulky, lightweight materials like wood chips and waste paper; characterized by high capacity, high speed, and low energy consumption.

Bucket Elevators: Capable of vertical lifting to save floor space; ideal for connecting storage silos with pretreatment equipment.

En-masse Conveyors: Feature superior sealing to prevent dust emission; suitable for powder or small granular materials such as wood flour and waste paper scraps.


II. Pulping Stage

Common Equipment: Screw Conveyors, En-masse Conveyors.

Advantages:

Screw Conveyors: Best suited for high-moisture, viscous pulp or semi-pulp; offer a simple structure and easy maintenance.

En-masse Conveyors: Provide stable operation in high-humidity environments; suitable for transporting non-free-flowing materials like pulp residue and wet fibers.


III. Paper Forming Stage

Common Equipment: Belt Conveyors.

Advantages: Used for the initial transport of wet paper webs; offer high load-bearing capacity and seamless integration with the press section.


IV. Drying and Finishing Stage

Common Equipment: Belt Conveyors, Slat Conveyors.

Advantages:

Belt Conveyors: Used for transporting dried paper rolls or sheets; ensure smooth operation to avoid scratching the finished product.

Slat Conveyors: Boast high load-bearing capacity for heavy paper rolls; ideal for sorting and transfer within finished product warehouses.


V. Waste Paper Recycling and Environmental Treatment Stage

Common Equipment: Belt Conveyors, Screw Conveyors, En-masse Conveyors.

Advantages:

Belt Conveyors: Efficient and easy to maintain for transporting baled waste paper.

Screw Conveyors: Capable of transporting wet materials like waste pulp and sludge without clogging.

En-masse Conveyors: Offer excellent containment for high-dust or polluting materials such as paper dust, ash, and slag.
