Description
Function
The incoming water flow is led into the wider section of the tank through the top-mounted inlet. A vertical plate creates an even laminar flow, which enables the solid material to settle. The outlet is positioned in the narrow section of the tank, which is fitted with an overflow channel to reduce the risk of particlemigration. The tank’s walls slope steeply to avoid the risk of bridging. Settled material is transported out via a shaftless pulling spiral for maximum dewatering. This shaftless spiral reduces the need for maintenance, as there is no bearing at the bottom of the through.
Design
As standard, classifiers are manufactured in stainless steel (1.4301) or (1.4436). The unit is fitted with a shaftless spiral made of black material (S355J0) in the bottom of the through. Throughs are coated with Hardox wear bars or Robalon wear liners.
