Abstract

Process for continuously mixing a rapid or quasi-instantaneous setting refractory product (I) e.g. a sand, in which at least a fraction of (I) is coated with one of the two constituents of a binder/hardener system (II) in a main classical type mixer, then the coated (I) is supplied to a secondary high speed small volume mixer in which is incorporated (a) the second constituent of (II) in the form of a liq. gas or aerosol or (b) the other fraction of (I) which has been previously coated with the second constituent of (II) in a second classical type mixer then the assembly of the components is mixed to obtain an homogeneous mixt. which is ready to harden, and finally the hardening (I) is projected into a mould or core box.
