Core sand preparation apparatus

Abstract

A binder system component metering apparatus for use in core sand mixing equipment comprising an elongate hollow vessel of substantially greater length than width and having upper and lower end portions, valves located in a lower end portion of the elongate vessel for introducing via hydrostatic pressure, liquid binder system components into the vessel so that as the vessel is filled the liquid presents an upper surface that rises vertically, and a sensor located in the upper end portion of the elongate vessel to continuously sense the position of the liquid surface at infinite locations along the length of elongate vessel whereby the upper surface rises with minimum turbulence.
