Raschig Ring

Raschig Ring

Ceramic Raschig ring is common regular packing that they are still used for refilling existing columns and other applications. Its surface ratio is higher than ceramic cylinders and balls by 30% and its ring shape has high mechanical stability. Ceramic Raschig rings is the first development of a random packing. Simple shape, it is the same height and diameter of the ring. Raschig rings large size (≥100mm) are structurally packed in the column, for small size>100mm below the Raschig rings and more filled with heaps way. Ceramic Raschig Rings with excellent acid resistant properties, the ability of resisting various inorganic acid, organic acids and organic solvents corrosion (except HF acid), high temperature in a variety of occasions, wide range of applications, can be used for chemical industry, metallurgy, gas and environmental protection industries in the drying tower, absorption tower, cooling tower, scrubber, regeneration tower.
