The grass residue screw press dewater machine, also known as a screw press dewatering machine, is designed to remove water from organic materials such as grass residue. Its principle of operation is based on the use of a screw and a perforated cylindrical screen. Here's how it works:

1.Feeding: The grass residue is fed into the machine's hopper or feeding chamber.

2.Screws and Cylindrical Screen: Inside the machine, there is a helical screw that rotates continuously. As the screw turns, it pushes the grass residue towards a cylindrical screen with small openings. The screw and the screen are closely aligned but do not touch.

3.Dewatering: As the grass residue is pushed forward by the rotating screw, water is forced out through the openings in the cylindrical screen. The screw applies pressure to the material, squeezing out the water as the residue moves along the screw.

4.Separated Water: The water separated from the grass residue through this process passes through the openings in the screen and drains out of the machine.

5.Dried Residue: The dewatered grass residue continues to move along the screw until it reaches the end of the machine. By this point, most of the water has been removed, leaving behind drier organic material.

6.Collection: The dewatered grass residue, now with significantly reduced moisture content, is collected from the end of the machine.

The efficiency of this process relies on the design of the screw and the screen, as well as the rotational speed of the screw. The size of the openings in the screen determines the size of particles that can pass through, affecting the quality of the dewatered material.

In summary, the grass residue screw press dewater machine uses the mechanical action of a rotating screw and a perforated cylindrical screen to apply pressure to the organic material, forcing water out through the screen openings and leaving behind dewatered residue.
