Perforated ball

1.adequate mechanical strength, chemical thermal stability 2.higher dispersion and flux of the fluids 3.big surface area Specifications

Embossed Slot Perforated Efficient Ceramic Ball (Patent No:2005201337860) is a new product .

Embossed Slot Perforated Efficient Ceramic Ball (Patent No:2005201337860) is a new product developed on the basic of KK perforated ceramic ball by slotting on the sphere, and by forming lot of knobs uniformly on the sphere of the ball. It can increase the surface area and free volume, and decrease the bulk density, It can increase flux of the fluids and decrease the resistance of the system. As a new efficient support and covering material of catalyst. It can be widely used in oil refinery,chemical,fertilizer,natural gas and environmental protection industries......
