The High-Density Extruder For Rugged, Reliable Operation

Sebright Products High Density Extruders were originally designed in 1992 to dewater wet rejects from the pulp & paper industry, where they routinely run around the clock unattended. Moreover, this demanding application requires the equipment to accept a wide variety of materials and be durable and low-maintenance. The High Density Extruder enjoys a significant market share in the pulp and paper industry, and because of this, many mills call it the “Sebright”.

Since 1992, High Density Extruders have been found to effectively dewater and compress a variety of wet materials, including grinding swarf, wet fiberglass, plastic recycling rejects, and packaged liquids. Our 30+ years of experience and continuous improvement have resulted in an effective, low-maintenance, and user-friendly hydraulic ram press.

Proprietary PLC Operated ADCS

Automated Densification Control System
The PLC monitors & maintains both the compression ram and the discharge restrictor plate pressures. Proprietary control logic (ADCS) automatically controls the restrictor plate hydraulic pressure to allow material discharge after dewatering and compression parameters are attained. Therefore, this allows a wide range of material to be dewatered. Consequently, most competing equipment has only manually adjustable restrictor plate pressure adjustments, which do not compensate for changes in material properties and variations in friction. As a result, creates either low liquid removal rates or equipment jamming issues.

Proprietary Timed Pressure Management

The High Density Extruder Dewatering Cycle is programmed to increase pressure incrementally over time. This is the key to providing superior liquid removal, flexible operation, and cleaner effluent liquids.

Timed Pressure Management does this by:

1. More time under pressure allows more liquid to escape
2. Programmable Parameters allow optimization of the application
3. Incrementing the pressure from low to high allows the material to dewater gradually, resulting in a higher solids capture rate.

Other equipment, such as reciprocating ram presses and screw presses, cannot duplicate both the superior dewatering and capture rates that our Timed Pressure Management cycle allows.
