Dewatering screw press is an efficient solution for pretreating high-organic-content waste like food scraps and kitchen waste. Designed to streamline the process, it shortens pretreatment time, offers quick startup, and adapts easily to various materials.

Our dewatering screw press delivers efficient, continuous processing within a compact footprint, making it ideal for facilities with limited space. It is specifically engineered to handle challenging materials that are prone to clogging, ensuring consistent and reliable operation even under demanding conditions.

With user-friendly operation and low maintenance needs, our dewatering screw press is an ideal choice for efficient and cost-effective waste management.

Main Features

Performance: Dewatering screw press is meticulously designed and manufactured to meet the demands of continuous or intermittent operation, frequent start-stop cycles, and startup under full-load conditions.

Bearings: The machine’s bearings are equipped with a sealing system and use imported brands such as FAG, SKF, or NSK, with bearing temperatures maintained below 65°C.

Gearbox: Dewatering screw press is fitted with imported brand gearboxes, including SEW, Siemens, Hansen, or equivalent.

Sealing: Exposed rotating parts are protected by guards that are bolt-fixed for easy removal and maintenance.

Dewatering Degree: The hydraulic system drives a conical backpressure mechanism to regulate pressure, allowing precise control of the moisture content.
