Abstract

A portable machine for blending two reagents to produce a resin spray incorporates a pair of gear pumps driven by rigid couplings from a pair of motors mounted on opposite sides of a supporting partition and located entirely within a tubular framework. Used for spraying coal or rock faces in mines etc. using portable equipment driven by compressed air. The design eliminates intermediate flexible plastics couplings involved in an alternative design which were found to be susceptible to damage or wear. The unit is also more compact.
