The metal pall ring packing is made of metal sheet, and two rows of window holes with inner extensor tongue blades are cut out on the ring wall. Every hole is five ligule, every tongue blade bending to the ring, pointing to the heart, photograph, almost in the center position of upper and lower layer hole is staggered, generally the area of the hole is about the size of ring wall of about 35%, as a result of pall ring packing in the ring wall opened many hole, makes the tower of gas and liquid can freely through from the window and the pall ring filler is one of the main ring packing was adopted.

Metal pall ring packing is in the 1940 s Germany BASF company developed on the basis of the raschig ring packing, it USES sheet metal is made, the ring wall on the two rows with a tongue of leaves and hole, window has five rows ligule bend into the ring, pointing to the ring, take almost in the center, two floors up and down hole is the location of the staggered, the area of the hole is about the general ring area of about 35%. The gas and liquid distribution and mass transfer performance in the packing layer are better than those in the Lacey ring because of many window holes in the ring wall.

There are many kinds of metal pall ring material, such as carbon steel, stainless steel 304, 304L, 410, 316, 316L, etc., for choice.

● Ball ring packing has the characteristics of low pressure drop, large flux and high efficiency. The metal packing has lower pressure drop and higher quality efficiency than the similar size pall ring, and the liquid distribution in the packing layer is good.

● Suitable for all kinds of separation, absorption, desorption device, atmospheric and vacuum device, synthetic ammonia decarbonization, desulfurization system, ethyl benzene separation, iso-octane/methyl benzene separation, etc.

● Small resistance, large flux, large flexibility of operation, high separation efficiency.

● Its processing capacity is much larger than the Rasch ring, if it is the same amount of processing conditions, its pressure can be reduced to less than half at the same time its mass transfer efficiency can be improved by about 20%.

● Its production capacity is very large, in the general case, the use of Bauer compared with the use of Laci ring to save about 35% of the packing volume.
