Typical principle process flow of kaolin beneficiation: rough separation adopts spiral classifier and hydrocyclone classification to remove a large amount of coarse sand. Φ42m sedimentation tank, Φ14-20m grading tank and centrifugal classifier are selected for grading, and the particle size distribution is strictly controlled. And according to the quality characteristics of the raw ore of each pit and the product quality requirements, chemical bleaching, high gradient magnetic separation or stripping operations can be taken respectively to obtain different grades of products.
The river channel sludge filter press is a special equipment, which is used to deal with river channel dredging sludge, lake sludge and sludge brought ashore by cutter suction boats. The equipment adopts the principle of automatic water removal and extrusion dehydration. First, the sludge is introduced into the equipment through a slurry pump, and after pressing and squeezing, the output is clear water and mud cake. This treatment method does not require manual unloading, and the moisture in the mud cake is effectively removed, which can be directly packaged and transported, and the clean water produced can be directly discharged. Automatic processing: The equipment adopts an automatic control system to realize automatic water removal and extrusion dehydration without manual operation, which greatly saves labor costs and time.
