Slotted & perforated ceramic ball
Description:
HQ-HK Slotted & Perforated Ceramic Balls is a new product developed on the basis of HQ-KK perforated by slotting for symmetrical slots on the sphere. It can increase the void space and flux of the fluids and decrease the resistance of the system. Furthermore, 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.
