Product details

The rotational speed of the main shaft can be regulated through a frequency converter. When the rotational speed of the spiral shaft is increased, the production capacity of the equipment can be improved. When the rotational speed of the spiral shaft is decreased, the dryness degree of the discharged material can be increased.

The first section that the slurry comes into contact with is the conveying spiral section. The spiral shaft in the middle part is a tapered variable pitch spiral shaft to increase the compression ratio, improve the filtrate extraction rate and the dryness of the slurry. The second half is the high-pressure spiral section, and the pitch of the spiral blades is arranged from small to large from the feed inlet to the discharge outlet.

The inner layer of the screen drum is a screen mesh, and the gaps between the screen mesh are arranged in this way from the feed port to the discharge port. The outer layer of the screen is a reinforced screen drum, and each screen is connected with bolts.

The cylinder plunger is used to adjust the dryness of the discharged material. When the dryness of the discharged material is low, the air pressure in the cylinder should be increased. When the dryness of the discharged material is high, the air pressure in the cylinder should be decreased. This adjustment should be continued until the dryness of the discharged material is suitable.

Factories Built

  • How easy is it to operate and maintain the machine?
    Screw press machines are generally user-friendly, with simple controls and a robust design for continuous operation. They come with manuals and often video tutorials for setup, operation, and troubleshooting. Maintenance involves regular lubrication, checking the screw and barrel for wear, and cleaning after use, which is straightforward due to accessible components. Suppliers typically offer technical support to ensure smooth operation.
  • How easy is it to operate and maintain the spiral press machine?
    The machine is designed for simple operation, often requiring minimal training. Basic models are manually operated, while advanced ones feature automatic temperature control and filtration systems. Maintenance involves regular cleaning of the screw and press chamber, lubrication of moving parts, and occasional replacement of worn components, all of which are straightforward with provided instructions.
  • What is the capacity of the spiral press machine?
    Capacities vary by model. Small-scale machines can process 1-10 tons of material per day, while larger industrial models can handle 20-50 tons or more. For instance, a common small-scale machine might process 500 kg per hour, making it ideal for home or small business use, whereas larger units suit commercial production.
  • Can the machine handle both cold and hot pressing?solutions
    Many models support both, with adjustable temperature settings. Cold pressing preserves nutrients, while hot pressing increases yield. Verify this feature with the supplier.
  • Can the machine be customized for specific needs?
    Yes, many suppliers offer customization options like capacity, screw design, or additional filtration. Discuss your requirements upfront.
