High Density Extruders for Liquid Extraction

The High Density Extruders are used to extract liquids from many types of industrial refuse byproducts, or to remove liquids from many commonly used packaged products and beverages. Tested and proven time and time again, the High Density Extruder is the best performing, most efficient and most reliable ram press available today.

About the High Density Extruders

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 major market share in the pulp and paper industry and because of this, many mills simply call it, the “Sebright”. Since 1992, The High Density Extruders have been found to effectively dewater and compress a variety of wet materials such as grinding swarf, wet fiberglass, plastic recycling rejects and packaged liquids. Our 30+ years of experience and continuous improvement has produced a very 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 does not compensate for changing material properties and differences 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. In fact, 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 to the application
3. Incrementing the pressure from low to high allows the material to gradually dewater and creates a better solids capture rate.

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