Improvements in or relating to devices for mixing foundry sands with synthetic resin binders or co, processed sands

摘要

Continuous discharge apparatus for mixing foundry sand with a binder comprises an elastic tube (1) positioned between the upper and lower runs of an endless band (2) which revolves the tube and flattens it, the unconstrained diameter of the tube being greater than that of the rollers (3). The tube may be inclined at an angle of one to thirty degrees to the horizontal.
