ABSTRACT OF THE DISCLOSURE Apparatus and method for conveying abrasive solids to a backfilling location wherein the solid materials are delivered to a blow-pot type loader, a vibratory feeder receives the discharge from the loader, and delivers the same to a pressurized conduit where air under pressure suspends the solid material and delivers it to the backfill location. The specific improvement of the present invention is concerned with a reciprocable slide valve which is disposed between the delivery means and the loader, the slide valve providing a substantially air-tight closure for the loader and eliminating the necessity for rotary feeding and metering apparatus which are subject to frequent replacement and repair.
