China 25mm 38mm 50mm Ceramic Raschig Rings Packing for Drying Columns

Chemshun Ceramic Raching Ring Introduction (Al2O3: 17~23%)

1: Brief Introduction :
Raschig ring is an artificial filler earliest industrial use. Usually made of ceramic or metal sheet having a height equal to its diameter, the size of conventional 25mm ~ 75mm (also as small as 6mm, large up to 150mm). Ceramic wall thickness of 2.5mm ~ 9.5mm, the metal ring is 0.8mm ~ 1.6mm, in the case of strength permits, should be thinned wall of the ring.
