YX series wet pressing strontium ferrite magnetic powders have been designed to produce all grades of hard ferrites. The users can produce high quality magnets by adding the provided additives into the powders. Our highly automatic instruments and strict quality control system ensure that the quality is stable and reliable
In order to ensure the high qualified granular material is purchased from our company, the particle should be dry ground to 3-5µ M at first, and then be wet ground in a sand grinding mill or ball mill to less than 1 µ M, and then be wet pressed. If the coarse ground powder is bought, it can be wet ground directly
1, Before grinding, the grinding mill should be cleaned thoroughly. And any materials from other factories or Impurity should not be mixed into our material.
2, Along with the powder (granular powder and coarse ground powder), we provide the secondary additives in separated bags, users should only add it into powder during grinding according to the requirement.
3, All the necessary secondary additives have been added into the fine powders (< 1µ M). So there is no need to add any other material, But two to three hours' wet grinding is necessary for better distribution of particles
4, During pressing, the moisture of slurry should be controlled between 32% to 37%, the pressure required is >4000N/cm2, and the magnetic field density is >560kA/m
5, Due to the actual sintering temperature measured by various suppliers' instruments are not the same, we can only provide sintering temperature of 1220° C to 1270° C for reference. Please note that the proper sintering temperature should be defined in accordance with the status of the sintered sample pill.
