Hydrocyclone an overview ScienceDirect Topics
A hydrocyclone is a highthroughput 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 gravityThe main areas of application for hydrocyclones are: • Mineral processing industry Hydrocyclones are frequently utilized in the metallurgical and mineral processing industry for the classification of fine particles and dewatering of slurries• Starch industry Hydrocyclones are commonplace in the potato starch, cassava starch, wheat starch and corn starch industry Hydrocyclone
