Portable mixing/delivery apparatus for pre-blended granular mixtures
First Claim
1. A portable mixing/delivery apparatus for dispensing mixed, wet granular material directly to a point of use for said material at a job site, said apparatus comprising:
- a support frame;
a container holding dry pre-blended granular material attached to said support frame;
a source of liquid;
a continuous mixer coupled to said source of liquid and attached to said support frame for receiving said dry pre-blended granular material from said container and converting said dry pre-blended granular material to a mixed, wet granular material for continuous discharge directly at the point of use; and
lift means attached to said support frame for receiving a lift mechanism for transporting the apparatus to the point of use.

Abstract
A portable mixing/delivery apparatus mixes dry pre-blended materials, such as homogeneous cementitious combinations of dry sand, cement, Lime, color pigments, etc., packaged in large bulk bags for use at a remote construction site. The bulk bag is lifted by a removable rack having plural lift eyes and the combination is positioned over a height adjustable frame. The granular material is then discharged into a continuous mixer having a dynamic input mixing stage, an output dry-to-wet mixing stage, and a transition stage therebetween. The entire assembly (bulk bag, frame and continuous mixer) is portable and can be lifted such as by a forklift to the height of a masonry scaffold for dispensing the mixed, wet granular material directly to the point of use. The apparatus allows the continuous mixer and its discharge tube to rotate to facilitate dispensing of the material directly to the point of use.
