Key Features of Multi-disc Screw Press
1. Efficient solid-liquid separation: Our dewatering screw press effectively separates solid and liquid components, resulting in a drier solid cake with lower moisture content.
2. Automatic control and continuous operation: Under the control of electric control cabinet, the machine can work continuously, with the medicine machine and inlet pump.
3. Self-cleaning system: The machine is equipped with a self-cleaning mechanism that prevents clogging and ensures smooth operation.
4. Good durability and low maintenance: The discs and screen are made of 304 stainless steel, and other parts are built with carbon steel, offering durability and requiring minimal maintenance.
5. High dewatering efficiency: After dewatering, the water content of solid cakes is about 60%.
6. Low energy consumption: The machine rotates at low speed, about 2~5 rpm, so the power consumption is extremely low.
7. Compact and space-saving design: The press has a compact footprint, making it suitable for installations where space is limited.
8. Versatile applications: The multi disk screw press can be used in various industries and is adaptable to different materials.

Structure of Multi Plate Screw Press
The main parts of a multi-disk screw press typically include:
1. Frame: The frame provides the structural support for the entire press.
2. Disks: The press consists of multiple disks stacked together in a vertical arrangement.
3. Screw shaft: The screw shaft is responsible for the movement and transportation of the sludge or slurry through the press.
4. Cylindrical screens: Cylindrical screen is to prevent the passage of solid materials while allowing the liquid to pass through.
5. Motor: A motor provides the power to rotate the screw shaft.
6. Control system: A control system is used to monitor and control various parameters of the press, such as speed, pressure, and dewatering efficiency.
Working Process of Multi-disc Screw Press
The working process of a multi-disc screw press involves several steps. Here’s a general overview of the process:
1. Feeding: The sludge or liquid-solid mixture is pumped into the mixing tank and combined with a polymer flocculant agent. The mixture is stirred thoroughly and then is fed into the screw press through an inlet pipe or a feed hopper.
2. Thickening: As the screw shaft rotates, the sludge or mixture is conveyed towards the discharge end. Through the pressing action of the screw and the force of gravity, some liquid is filtered out through the screen.
3. Dewatering and Discharging: The thickened sludge continues to move forward with the rotation of the screw shaft. As the screw pitch gradually decreases, the water in the sludge is squeezed out and discharged through the drain pipe. Simultaneously, driven by the continuous rotation of the screw shaft, the solid cake is ultimately pushed out from the discharge end of the press.
4. Self-cleaning: When the screw shaft rotates and pushes the sludge forward, it also drives the swimming ring to clean the screen. This self-cleaning mechanism helps prevent clogging and ensures uninterrupted operation of the screw press.
By following these steps, the multi-disc screw press efficiently separates the liquid and solid components of the sludge. This makes the sludge easier to handle, transport, and dispose of.
