Abstract
A pre-mixer agglomerator and method of pre-mixing batching ingredients used to produce concrete mixes is disclosed. Specifically, this invention involves a pre-mix system which blends the wetting agents and the cementitious ingredients in relation to each other at any selected ratio in an adjustable and repeatable manner. The pre-mixer is a twin screw, preferably counter-rotating, pre-mixer agglomerator unit for pre-mixing these materials prior to combining them with aggregates in a drum of a transit mixer truck or other final mixing vessel.
