rotorwet grindingfor wastewater treatment

Product Overview
Non-drum grinder designed for underwater installation; suitable for flow rates up to 340 m3/h and engineered to pulverize solids to approximately 8-12 mm to protect downstream pumps and piping.

Introduction
The Wastewater Grinder from Lian Tai Machinery is a high-torque, low-rotating-speed, double-shaft unit optimised for submerged applications. It pulverises a wide range of solids (textiles, plastics, wood, aluminium cans, glass bottles and general debris) into small particles that pass through pumps and pipelines without causing blockages. The unit is intended for use in wastewater and sludge systems where interception and size reduction of floating and suspended solids are required.

Advantages

• Can be driven by either an external (dry) motor or a submersible motor, providing installation flexibility.
• Particularly suitable for construction of ground pump stations and for improving pump-station environments.
• Reduces sewage solids to small particles (typically 8-12 mm; some references cite 6–10 mm), enabling solids to flow with the water.
• Eliminates the need for additional conveying or compaction equipment.
• No secondary pollution to the surrounding environment when correctly installed.

Specifications
Key technical features include double-shaft underwater design, high torque with low rotational speed, and motor options (external or submersible). The unit is suitable for systems with flow rates up to 340 m3/h and provides typical pulverized particle sizes of 8-12 mm (other references note 6–10 mm). Detailed parameters are available in the technical datasheet image on the product page.
