A hydrocyclone is a high-throughput gravity separation device used for separating slurry particles based on particle weight. For example, particles of similar size but different specific gravity, or particles of different size but identical specific gravity. Cyclones are also commonly used for dewatering of slurries given that they are much faster throughput …

HICTECH Dense Medium Cyclones (DMCs) are designed and manufactured to order, ensuring every cyclone is 'fit for purpose' prior to manufacture. The process evaluates the operating conditions of the plant in which the cyclone will be installed. This evaluation provides the required data which is then analysed through a dynamic processing model.
