Abstract

Method for the preparation of foundry sands incorporating a rapid, self-hardening binder, in which the various constituents are automatically dispensed separately into a mixer from where, after mixing, the resultant material is transported immediately to the relevant moulding machine. Speed of operation. The materials are fed into a paddle mixer having a funnel shaped mixing basin, from the two gravity-operated bins and an Archimedes screw feed from one side, the non-active constituents being pre-mixed prior to the addition of the hardening agent. The whole paddle can be lifted out of the mixing bowl, and moved sideways for easier, and quick emptying, and cleaning of bowl, and paddle.
