Design of Pulp Screw Press

The design of paper pulp dewatering machine also utilizes a screw press mechanism. The main parts of the machine is a rotating screw and a cylindrical screen. After feeding the pulp into the machine, the screw conveys it towards the outlet while squeezing water to pass through the screen and the dewatered pulp is discharged at the end of the screw press, resulting in the separation of water and solids.

However, there are some differences in their specific designs for different materials. For example, pulp dewatering machines may have finer screens to retain smaller pulp particles and fibers. In addition, the screw may have a relatively smaller pitch to provide better compression and dewatering efficiency.

Why Invest In A Pulp Dewatering Machine?

Pulp dewatering screw press is an essential part in paper production. It reduces the moisture content of the pulp before further processing. Here are some reasons why use pulp dewatering screw presses:

The dewatering process removes a large amount of water from paper pulp, resulting in a higher dryness of the pulp. The dewatered pulp is easier to handle, transport, and store, which will reduce transportation, storage and handling costs.
By effectively extracting water from pulp, it can increase the production capacity of pulp and paper mills. Also, it will reduce the energy consumption and improve the efficiency in furthering processing.
Dewatering paper pulp also helps improve the quality of the final product. Pulp with lower moisture content has better strength properties, resulting in higher-quality paper products.

Applications of Pulp Dewatering Screw Press

The pulp screw press isemployed for dewatering sludge, municipal wastewater, winery wastewater, slaughterhouse wastewater. By separating the liquid from solid sludge, the screw press reduces the volume of waste and facilitate its disposal or further treatment.

This machine is highly efficient to separate liquid from solid components in animal waste, such as cow dung, pig manure, poultry manure, duck manure, and other organic wastes. Through dewatering, it can greatly reduce the volume of manure,  making it easier and more cost-effective to handle, store, and transport.

Screw presses can be used to dewater the biogas slurry to remove excess moisture, which can increase the biogas yield. In addition, the overall volume of material is reduced, allowing for smaller storage and digestion facilities. This results in cost savings in terms of infrastructure, space requirements, and transportation. And the dewatered material can be further processed or used as fertilizer.

In the food processing industry, pulp screw presses are used to extract juice from fruits and vegetables. Also, it can remove the water content of waste fruits and vegetables, brewer’s grains, and other organic waste to reduce waste volume for further disposal.
