In 1990, Young Industries made several 20” Model LH Rotary Valves for handling abrasive corn-based powder. These valves were manufactured with heavy wall housings with interior bore hard surfaced with Stellite. In 2017 our Engineers were contacted by the user to discuss a change in the application for one of the 20” rotary valves. For this application the rotary valve would be required to comply with NFPA 69 standards. After the initial discussions with the user it was decided that one of the 20” Model LH Rotary Valves would be returned to Young Industries for an evaluation to determine if it could be refurbished and used for the application.

The problems in the handling of titanium dioxide are well known, either by its bad reputation or by experience. TiO2’s small particle size, cohesiveness, and irregular shapes make it stick everywhere. Also, the better grades of pigment are harder to handle.

A standard holding hopper will cause titanium dioxide powder to bridge and not discharge. Hammer Rash is the result of trying to make Ti02 flow.
