Abstract (en)

The particle size of solids. particularly of solids such as drill cuttings, recovered from a subterranean wellbore is reduced by pumping (18) the solids in a fluid medium from a tank (12) through a choke (30) to impinge on a surface thereby abruptly retarding movement of the solids to thereby induce breakage or grinding thereof. <IMAGE>
