Features of Improved Concrete Mixing Plant

An improvedis mounted on several mobile chassis to provide portability. The plant includes a horizontally oriented, internally urethane coated mixing drum having spiral and lift flights such that the rate of discharging concrete material is controllable without altering the direction or rate of rotation. A water dispensing system wherein the water is automatically measured volumetrically or, alternatively, gravimetrically provides automatic cleaning of internal surfaces of the mixing drum as an integral part of the concrete mixing pant.

Pourable wet concrete material is readily available from numerous concrete mixing plants that place various ingredients for mixing concrete material into a special purpose truck that mixes the ingredients into the concrete material as the truck is driven to the jobsite where the concrete material is needed. One of the problems with erecting a at jobsite is the expense involved. Another problem with available portable jobsite concrete mixing plants is the procedure which must be followed in order to reduce airborne particulate contamination to acceptable levels.
