Grit Classifier

SANDSEP^®

The SANDSEP^® is a highly efficient unit designed to separate grit and other pollutants from process and effluent streams.

The design of the inlet section reduces turbulence to a minimum and creates an optimum flow pattern for efficient settling.

The solids settle in the bottom of the classifier which contains a spiral. The spiral transports the sediment slowly (speeds are kept to around 5rpm to minimise turbulence) to an inclined or vertical conveyor which then discharges the grit.

PRODUCT BENEFITS

Spiral conveying = no build-up will ever occur and no intermediate or end bearings under water
Few moving parts result in a compact and robust design = low maintenance and operating cost.
Low speed/RPM = long life-expectancy and high torque.
Low energy consumption = cost savings.
Complete aftermarket support available.

TECHNICAL DETAILS

Grit S.G ≤2.65 with an average B.D of 1600kg/m³ (100lb/ft³).
Hydraulic capacities from ≤5l/sec. (0.1MGD) to ≤35l/sec. (0.8 MGD).*
Dryness of output product – typical 60% to 80 % D.S (Subject to sparge and wash options – prior to discharge).*
Organic residue; typically, ≤15% with the combined spray bar and sparge tube options.*
Shaftless spiral – that do not require a centre-pipe, intermediate or end bearings – thus minimising any potential for undesired blockages.
