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.
Features and benefits
Spiral conveying = no build up will ever occur and no intermediate or end bearings under water
Robust design
Low speed = long life expectancy
Low energy consumption = cost savings
Robust design = low maintenance
Virtually maintenance free
