In an egg tray manufacturing plant, the paper pulper machine system is the starting point of the entire process and plays a key role in determining product quality and production efficiency. The system mainly consists of a hydraulic pulper, pulp mixing tanks, supply pumps, and vibrating screen filters. These machines work together to process waste paper into uniform, properly concentrated pulp, ensuring a steady supply for the forming machines.
Function of Paper Pulper
The pulping system is a core component of the pulp molding production line. It is primarily used to break down and mix raw materials such as waste paper, producing a uniform pulp for the subsequent forming process.
This equipment is widely used in the production of various pulp-molded products such as egg trays, cup holders, fruit trays, and industrial cushioning inserts. It plays a key role in improving both product quality and production efficiency.
Wide Range of Applicable Raw Materials
This pulper machine for paper supports various types of waste paper materials, including:
- Old newspapers
- Carton paper, book paper
- Paper scraps, cardboard, etc.
Through hydraulic agitation and shearing, the raw materials are quickly broken down into pulp without the need for complex pre-treatment. The operation is simple and highly adaptable.
Paper Pulper Machine Process Flow
1, Hydraulic Pulper – Pulping
Raw materials (such as waste cartons, newspapers) are fed into the hydraulic pulper for pulping → The pulp slurry flows into the storage tank for later use.
2, First Mixing Tank + Vibrating Screen Filtration
Pulp is pumped into the mixing tank → Passes through a vibrating screen to remove impurities → Stirring adjusts pulp concentration.
3, Second Mixing Tank – Additive Blending
Pulp enters the second tank → Additives like pigment, waterproofing agents, etc., are added → Thorough mixing.
4, Pulp Supply Pump to Forming Machine
Prepared pulp is delivered by the pump to the egg tray forming machine for continuous automatic production.
What are the Advantages of Pulper System?
- Various sizes to meet different production needs, suitable for both small and large-scale operations.
- Handles a wide range of waste paper types such as newspapers, cartons, books, and cardboard.
- Paper pulper machine size, motor power, and feeding methods can be customized based on factory layout and capacity needs.
- Optimized impeller ensures uniform mixing for consistent and strong pulp output.
