An overflow device is associated with the body member for establishing the upper level of a pool of abrasive slurry in the cavity. At least one flow-restrictive conduit component is secured at one end to the body member, communicates with the cavity at the lower end of the pool of abrasive slurry, and presents an outer end from which abrasive slurry is discharged. One of the above-indicated elements is movable whereby to selectively adjust the vertical distance between the plane of the upper level of the pool of abrasive slurry and the plane of the outer end of the conduit component.
