Carbon black feeding pump, independently researched and developed by Doright, is a new product of improving feeding stability of carbon black granulator. Carbon black feeding pump is consisted of pump body, rotor, end cover and gear. It is engaged of two rotors and transport materials in cavity forming from rotate. Transporting materials depends on the weight principle, more important, it depends on the push role of materials when rotors engaging, so the flow rate of feeding pump is not affected by pressure fluctuations and bed height. Velocity difference of two rotors exists in transient contact point, so rotors have self-washing surface function. Clean surface of rotors ensures permanent volume of transporting cavity and permanent delivery value of feeding. Rotor, pump body and end cover are precisely casted by high heat resistant stainless steel. The materials that are easily damaged and corroded are designed to increase the material thickness. Carbon black feeding pump has the following features: - Reliable and steady permanent materials, which could help to improve quality and efficiency of granulator. - Longer life time and fine air tightness without material leakage. - In the steady process, carbon black feeding pump can use cascade control with granulation water, which could avoid instability caused by granulator power and cascade control of granulation water. - Simple construction and easily maintenance. It is skid-mounted, and very easy to install.
