Activated alumina balls are regenerable
Gongyi Zhengda Water Supply Science tells you that the activated alumina ball can be regenerated. The activated alumina (except fluorine) produced by Zhengda Water Supply Material Factory in Gongjinkou, Gongyi City can be used together with household fluorine removal cylinders. It is an ideal drinking water defluoridation device in the family. Activated alumina can also be used in conjunction with water removal plants or fluorine removal units for industrial use. Activation of fluorine removal filter for household fluorine removal equipment: Dispose of aluminum sulfate solution (3 liters of water, 0.3 kg of solid aluminum sulfate), put the activated alumina aluminum defluoridation filter into the above solution, soak for 5-10 hours to discard the immersion liquid (Spoke properly when soaking), then wash with water for 3-5 times, each time with water about 2 liters, or regenerate by PH method, the pH value is controlled at 7.5. Activated alumina defluorination filter can be used continuously for 6-8 years. When the surface appears yellowish brown, the effect of removing fluorine is obviously reduced. This is caused by impurity pollution in the water. Therefore, it is best to treat it once every half a year with 3% dilute hydrochloric acid. The method of operation is the same as the regeneration method.
It is a fluorine-removing activated alumina ball generally having a spherical diameter of 1-2 mm, 1-3 mm, 2-4 mm, an activated alumina ball used as a desiccant in an air compressor, or other alumina balls used in drying. Generally, the ball diameter is 3-5mm, 4-6mm, 5-8mm, and the like. For details, please contact us.

Deep groove Ball Bearing is the most representative structure in rolling bearing, which is widely used. In addition to radial load, this kind of bearing can also be loaded with bidirectional axial load. The friction torque is small, and it is most suitable for adjusting rotation, low noise and low vibration. Bearings are widely used in automobile, electrical, instrumentation, construction machinery, agricultural machinery and various professional machinery. This kind of bearing has open and closed deformation structure. 
Deep groove ball bearings consist of an inner and outer ring with a cage containing a complement of precision balls. The standard Conrad-type bearing has a deep-groove construction capable of handling radial and axial loads from either direction in versatile designs that permit relatively high-speed operation.
