Channel Screen

The CSS and SSS screw screens, available both with and without a compactor, are innovative systems designed for solid-liquid separation. They adeptly perform two key operations: filtration and compacting. These screens incorporate a basket, which can be constructed from either perforated sheet or wedge wire, functioning as an effective filter. This is followed by a tubular transport section, leading to a compacting and dewatering module that can be equipped with either a chute or a bagging system.

In these systems, screenings are transported by a shaftless screw, which is fitted with bolted plastic brushes within the screen basket section to ensure consistent cleanliness. The process culminates in the compacting and dewatering section, where there is a significant reduction in both the volume and weight of the material, achieving up to a 40% decrease.

Designed for versatility, these machines are typically installed inside a channel that matches their width requirements. The CSS or SSS screens are suitable for channels up to 850 mm wide. They offer a range of manufacturing materials, including various grades of stainless steel (304, 316, or Duplex) and high-strength carbon steel, with the spiral component available in either carbon steel or stainless steel.

Additional options can be added to the basic configuration of these machines, such as custom-made discharge chutes and washing systems for both the basket and the transport section. Standardly, the compacting module includes a washing system to mitigate odor issues, with each washing system operable manually or via a solenoid valve.

Key advantages of the CSS and SSS screw screens include:

• High efficiency in operation.
• Simplicity in design.
• Extremely easy installation.
• Very simple maintenance requirements.

Typically, maintenance involves replacing brushes every two years, a task simplified by the unique auxiliary pivoting system that allows for easy on-site maintenance, even by untrained personnel.

Upon request, these units can be supplied with a control panel, available in either electromechanical or PLC-controlled formats, to suit various operational needs.
