Mineral Processing Machinery High Rate Lamella Plate Clarifier Thickener

Mineral Processing Machinery High Rate Lamella Plate Clarifier Thickener

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 lamella 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.

The lamella principle uses several parallel inclined plates to maximise the available settling area for any available floor area. In this way, the size and cost of the gravity settler can be minimised by matching the clarifying and thickening requirements more closely.

Applications

Effluent Treatment

Primary clarification of wastewater streams.

Pulp and paper industry.

Industrial water treatment systems.

Municipal water treatment systems.

Biological purification processes.

Wash water recirculation systems (eg. potato and root crop processing).

Wet scrubber and slaking effluents in the power industry.

Other Common Applications

Thickening processes in the chemical, mining and mineral industries.

Treatment of effluents in metal finishing, and iron and steel plants.

Working Principle:

Firstly, mineral liquid is mixed uniformly and then carried into thickener. Secondly, by the action of cohesive and gravitational force, the majority of overflows are overflowed through the overflow groove. The minority of overflows form small cyclone inside the settling area and subsequently are compressed in the compressive area. As a result, granules are compressed by gravity and then fall down, while clear liquid moves upward. Finally, concentrations are discharged from the lower underflow tube.
