Advantage of Our Screw Press Screen | Screw Press Basket

The solid-liquid separator has a long service life and hardly needs maintenance. The only consumable part is the wedge wire screen cylinder.

The quality of the drum screen is crucial for the manure separator.

  1. Advanced welding technology unlike other manufacturers, our v wire screen products are fused using ring fusion welding technology.
    This welding process is stronger, and the vee wire screen will not be damaged and deformed.

    Each batch of our products will go out for a stress test report.
    50% longer service life than similar products.
  1. Accurate gap (slot) size (0.2mm, 0.5mm, 0.8mm or as your need)
    The solid-liquid separator can process a variety of farm manure, including chicken manure, duck manure, cow manure, pig manure, etc.

    Different materials need Johnson drum screens with different gap sizes. We will strictly control the slot size tolerance according to the customer’s requirements.
  1. The special surface treatment process
    Environmental friendly physical cleaning technology can improve the smoothness of the screen barrel surface, improve its wear resistance and corrosion resistance.
  1. The perfect quality inspection system
    Raw material inspection

    Gap detection
    Dimension detection
    Pressure test
    Packaging inspection
    Roundness detection
    If the product has any quality problems, we will exchange it within 72 hours.
  1. Roundness high
    High roundness is the basic requirement of our wedge wire mesh products. Whether it is applied to any industry, roundness testing is our most important quality inspection item.

Drum Screen Maintenance

Regular cleaning
In order to ensure the efficiency of the screw press separator, wedge wire filters should be maintained regularly.
Determine the time of each cleaning according to the usage.
It should be noted that if chicken manure is treated, the frequency of cleaning should be increased.

  1. Wash the screen with high-pressure water once every 1-2 months. After cleaning, please pay attention to the installation position of the screen.
  2. If you see less affluent at the liquid outlet, clean the screen.
