Ceramic mini lessing ring is an advanced products based on ceramic raschig ring. It added the Minus partition on the ceramic raschig ring.The larger size ceramic mini lessing ring (ranging from 80 mm to 200 mm) is commonly be used as supporting packing on the bottom of packed column.
Features & Benefits:
Acid and alkali resistance.
Large flux.
Low pressure drop.
High mass transfer efficiency.
High compressive strength.
Large voidage.
Applications:
Ceramic mini lessing ring can be used in drying towers of chemical, metallurgy, gas, and environmental protection industries.
Ceramic mini lessing ring is widely used as supporting material at the bottom of packed tower.
