User Guide for Screw Press Dewatering Machine

Tianzhong Machinery, a trusted provider of screw press dewatering machines, offers a user guide and maintenance guide for our equipment, enabling you to ensure the machine’s performance and reliability.

User Guide

1. Pre-Operation Inspection

Before using the screw press machine, it is crucial to thoroughly inspect the equipment for any damage or issues. Pay special attention to critical components like the screw and screen, to ensure they are in good condition.

2. Material Feeding

Evenly distribute the material to be processed into the feed inlet of the screw press machine. Additionally, remove any foreign matter and other things from the machine, such as big fruit branches, stone, and metal, to avoid damage to the screen.

3. Starting the Machine

Once the material was fed, start the dewatering machine. Follow the instructions provided with the equipment to gradually increase the screw’s rotation speed, allowing the material to be progressively compressed and dewatered by the action of the screw.

4. Adjusting Outlet

Screw press machines from Tianzhong Machinery typically feature adjustable outlet parameters that can control the dewatering effect. You can adjust the parameters according to the material’s characteristics and the desired moisture content of the dewatered solids.

5. Monitoring the Dewatering Process

While the dewatering machine is in operation, continuously monitor the dewatering progress on the material. A gradual reduction in expelled liquid content signifies effective dewatering.

6. Shutdown and Cleaning

Once the dewatering process is complete, start by decreasing the screw’s speed. Wait for the screw to come to a complete halt before shutting down the equipment. Clean the residual material from the interior of the machine to prevent any impact on future operations. At Tianzhong Machinery, the casing is detachable, which makes it easy to clean and maintain the screen and screw.
