The phosphate stone separation processing from impurities and non-phosphate materials for use in fertilizer manufacture consists of beneficiation, drying or calcining and grinding. Phosphate stone from the mines is first sent to beneficiation units to separate sand and clay and to remove impurities.
Phosphate beneficiation plant involves many different types of machines such as phosphate quarry machine, stone crusher, phosphate powder grinding mill, phosphate separation machine, drying machine, processing plant etc.
Phosphate Beneficiation Application
Beneficiation of ultrafine phosphate is the process of recovery of phosphate particles less than 20 lm in size. It has been standard practice over many years in the phosphate industry to separate and discard the ultrafine particles, due to unacceptable processing difficulties such as excessively high viscosity and poor fiotation recovery.
In contrast with the established methods of beneficiation of phosphate where classification by hydrocyclone is mainly used to remove ultrafine as tailings, the method described in this paper allows a high proportion of ultrafine to be recovered via fiotation without prior separation.
Phosphate Crushing Machine for Beneficiation
Crushing is the first stage in phosphate beneficiation process. Primary size reduction generally is accomplished by crushers and grinding mills. Some classification of the primary crushed stone may be necessary before secondary grinding takes place. Extensive crushing and grinding is necessary to liberate phosphate from the material. Stone maybe crushed in two or three different phases: primary, secondary and tertiary crushing. Stone crushing process often involves one or more phases of screening to separate the different sized varieties.
The often used phosphate crushing machine includes jaw crusher, impact crusher, cone crusher, mobile crusher etc. Crushing machine is the important phosphate beneficiation plant. It produces fine particle size, and prepares for further processing. SBM is global supplier of service for consulting, design, manufacture of mining equipment.
