Inclined plate principle
Metso's inclined plate principle uses parallel inclined plates to minimize floor area occupation. The size and cost of the gravity settler can be reduced by matching the thickening and clarifying requirements more closely. Two basic criteria for gravity settling equipment are good clarity of the overflow liquid and maximum density of the underflow solids discharge. The area needed to clarify a suspension is often greater than that needed for thickening. This means that in a cylindrical thickening tank, the lower section with rakes and drive mechanism can be oversized. Metso IPS has proven interesting in the Potash Industry.
Prefabricated units with up to 500 m2 settling area.
How it works
The Inclined Plate Settler (IPS) consists of two main components, the upper tank containing the lamella plates inclined at 55° and the lower conical or cylindrical sludge tank.
The feed for the IPS enters through vertical chambers on either side of the plate packs and passes into each plate gap through slotted feed ports. Clarification takes place above the suspension inlet so there is no mixing of the clarified fluid with the incoming feed.
Above each pack is a full-length overflow launder fitted with throttling holes to create a slight hydraulic back pressure on the incoming feed stream. This method of feed control guarantees equal distribution to all inclined plate pack chambers with minimum turbulence at the entry points.
The solids settle onto and slide down each plate pack to the sludge tank where the solids are further thickened and compressed with the assistance of the raking system.
