Pulp Molding Machine manufacturers


New member

The paper pulp moulding machine using waste paper as raw material, the vacuum forming molds suck the pulp, and forming into pulp moulding products, and then after drying process, can get the final products.
The paper pulp moulding machine now is widely famous in Middle east countries, South American countries and Africa countries, it is easy operation, and environmental protection, so this project is very good for new investors.
Usually the paper pulp moulding machine can make different kinds of pulp moulding products by replacing different molds, so it can meet the needs of market very easy.
Our paper pulp moulding machine systems are made in modules. They can be easily connected together to ease installation (and also easily expanded, due to the module layout we use).
A. Pulping system
1) Hydrapulper: Breaking the waste paper by stirring knife, and then the initial mixing of waste paper and water, obtain the original pulp; Stainless steel sieve plate and impeller knife; Vertical type, 24 hours uninterrupted for supplying pulp.
2) Paper feeder: Supply waste paper to the hydrapulper automatically; Material: Fireproof and Skid-proof rubber; Gear motor control.
3) Pulp vibrating screen: Preliminary screening the pulp through the frequency vibration, filter out impurities from pulp;
4) Pulp pool agitator: Mixing the pulp in the pulp pool or tank, and keep the concentration of the pulp steady; The mixing arms are controlled by gear motor.
5) Sewage pump: QW model submersible sewage pump; Two of them are used for transferring the pulp from pulp pools to forming machine, another one is used for supply water to hydrapulper and pulp pools; The rest one is used for transfer original pulp to pulp supply pools.
6) Pulp refiner: ZLC model multiple performance high efficiency milling pulp desanding machine; Function: Break pulp fiber and remove impurities furtherly.
B. Forming system
1) Automatic forming machine
• Production capacity for 30 packed egg tray: 2000-6000pcs per hour.
