Belong to a hematite hematite quartzite, the main useful minerals hematite and limonite small amount of magnetite. The gangue is mainly quartz . The particle size of iron minerals and quartz is very fine, and the average monomer grain is 0.04 to 0.2 mm. Among them, 0.02-0.1mm grain size accounts for 80%. The reverse flotation process and conditions of the cationic collector are shown in the figure.

Four heavy axles and sealed
There are two steel bearing protection circles between the mixing arm and shaft.to prevent coarse sand.In the steel circles there is a airway. When certain pressure of air goes though it,a pressure protection mat will be formed between the interface of the mixing arm and shaft to prevent water and mud from close to shaft head and prolong the service life of the mixer.
