Theory and operational characteristics of the magnetic valve for solids Part II: Collar design

This paper reports on the operating characteristics of the collar type MVS which uses either orifice plates or screens as supports for the solids. The optimum placement for the support (screens or orifice plates), the current needed to operate the valve as a function of vessel size (up to 0.55 m) and screen or orifice opening, and the response characteristics of the valve were all determined. These findings were then compared with theory. Finally, the operational characteristics of the MVS (magnetic valve for solids) when handling a mixture of magnetic and nonmagnetic solids were briefly examined.
