Up to 98% Separation Efficiency | Shaft-Mounted Reducer (No Coupling) | LSSF Spiral Sand-Water Separator | Sewage Plant Grit Chamber Mixture Separation
Product Overview
The LSSF Spiral Sand-Water Separator is a professional solid-liquid separation device specifically designed for grit chambers in sewage treatment plants. It efficiently separates sand-water mixtures discharged from sedimentation tanks. Key components include a shaftless screw, lining strips, U-shaped trough, water tank, baffle, effluent weir, and drive unit.
During operation, the sand-water mixture enters the water tank from the top. Heavier sand particles settle at the bottom and are pushed by the shaftless screw along the inclined trough. The sand continues to move and dewater after leaving the liquid surface before being discharged into a sand bucket, while separated clear water exits through the overflow port and returns to the plant's inlet pool.

Key Features
Ultimate Separation Efficiency
Boasts 96%~98% separation efficiency, capable of precisely separating fine sand particles with diameter ≥0.2mm.
No Underwater Bearings
Shaftless screw design eliminates all bearing components submerged in water, preventing mechanical failures and simplifying maintenance.
Advanced Shaft-Mounted Reducer
Utilizes shaft-mounted reducer design that eliminates traditional couplings, enabling fast and straightforward installation and alignment.
User-Friendly & Easy Maintenance
Quick-release lining strips for rapid replacement and adjustable screw axial position for fine-tuning safety clearance between tail and tank wall.
Frequently Asked Questions
How small of a sand particle can this separator handle, and what is its efficiency?
The equipment has very high separation precision, effectively separating fine particles with diameter ≥0.2mm. The overall sand-water separation efficiency reaches 96%~98%.
Since the screw operates underwater, are the bearings prone to water damage?
They will not be damaged because this equipment uses a shaftless screw design, meaning there are no bearings located underwater at all. This completely solves the common issue of water-damaged bearings found in traditional equipment.
Is the installation and future replacement of wearing parts complicated?
It is incredibly simple. The reducer utilizes an advanced shaft-mounted design that does not require a coupling, saving complex alignment and installation steps. Additionally, the internal lining strips are quick-release, making future replacements extremely convenient.
