High Rate Thickeners Solid Liquid Separation
The HighRate thickeners became popular in the mid 1980's and are relatively newcomers to the sedimentation line of equipment As already discussed previously Thickeners are a major component in a plant layout and occupy HighRate Thickeners HighRate Thickeners, or Clarifiers, recover immediately reusable process water for mineral and aggregate producers, as well as environmental contractors Thickeners are beneficial in a variety of applications, including areas where water is in short supply or very expensive, recirculated water is not suitable for reuse in a plant, ponds are HighRate Thickeners McLanahanHighrate Thickener Highrate Thickeners are designed to provide roughly 12 times the throughput of conventional machines of similar size The key features for highcapacity thickeners are the feedwell design and the feed slurry dilution methodHighrate Thickener
