Apparatus for pumping and mixing high aggregate plural components of differing viscosities
First Claim
1. An apparatus for pumping and mixing plural components of differing viscosities comprising:
- at least two hoppers, each hopper comprising a hopper outlet;
a plurality of spaced dividers positioned vertically over the hoppers defining areas for adding each component to the hoppers, and one area for adding aggregate to each hopper;
an auger rotatably secured within each hopper, the auger being adapted to wipe the inside surface of its respective hopper during rotation;
a piston pump in communication with each hopper outlet, each piston pump comprising a pump inlet and a pump outlet, and each piston pump adapted to be joined by a coupling yoke, whereby components of differing viscosities can be pumped at a desired mix ratio anda static mixer comprising;
a mixer inlet; and
a mixer outlet, whereby plural components of differing viscosities can be uniformly pumped and mixed and observed.

Abstract
An apparatus for pumping and mixing plural components of differing viscosities having at least one hopper for accepting each component, each hopper having a hopper outlet; an auger secured within each hopper, the auger being designed to wipe the inside surface of its respective hopper during rotation; a piston pump plumbed to each hopper outlet, each piston pump being substantially identical and having a pump inlet and a pump outlet, and each piston pump designed to be joined by a coupling yoke, whereby components of differing viscosities can be pumped uniformly; and a static mixer. The static mixer has a mixer inlet and a mixer outlet, and is designed so that plural components of differing viscosities can be uniformly pumped and mixed.
