Portable cement mixing apparatus with precision controls

An apparatus for producing a cementitious slurry at a remote work site from a plurality of ingredients comprising:

• a platform;
• a plurality of storage containers for ingredients of a cementitious slurry supported by said platform;
• a mixing chamber suitable for receiving an ingredient from each storage container, said mixing chamber having at least three feet;
• a strain gauge load cell positioned between each of said feet of said mixing chamber and said platform, each strain gauge load cell is configured to communicate weight data and said strain gauge load cells are suitable for weighing the amount of each individual ingredient delivered to the mixing chamber in real time;
• a plurality of conveyors suitable to convey cementitious slurry ingredients from each of the plurality of storage containers to the mixing chamber;
• a water tank supported by said platform;
• a pump within said water tank;
• a hose having a first end attached to said pump provides fluid communication between said water tank and said mixing chamber;
• a nozzle attached to a second end of said hose conveys water into said mixing chamber;
• at least one valve carried by said hose, said valve located between said pump and said nozzle;
• and,
• an operating system configured to receive weight data from each of said strain gauge load cells and to cause, control and monitor the rate of conveyance of individual ingredients from each of the plurality of storage containers into the mixing chamber and to end the conveyance of individual ingredients from each of the storage containers by accurately monitoring the weight of each ingredient in the mixing chamber as reported by said strain gauge load cells to said operating system, the operating system also configured to monitor the rate of conveyance of water from the water tank into the mixing chamber and the weight of the water in the mixing chamber as reported by the strain gauge load cell and said operating system is also configured to account for the weight of water emitted from the nozzle but not yet in the mixing chamber.
