The technical application of white carbon black dispersion grinding pulp pump and the wide application of white carbon black production technology and grinding equipment. White carbon black is a general term for white powdery X-ray amorphous silicic acid and silicate products, mainly referring to Modified silica, precipitated silica, fumed silica, ultra-fine silica gel and aerogel, as well as new materials such as powdered synthetic aluminum silicate and calcium silicate. Secondly, the colloid mill of the white carbon black grinding pump equipment uses special dynamic seals, rotating body members, and special structures of the pump body. Water-cooled, positive-pressure, positive-installation mechanical seals will not damage the dynamic seal resistance under the liquid self-cooling cycle Pressure and long service life. And durable performance, good sealing performance and mechanical properties.
