摘要： A method of forming a mixture of powdered material and water includes the step of providing a hopper, a holding tank, a tube intermediate the hopper and the holding tank, and an air-powered auger arranged to feed powdered material from the hopper through the tube to the holding tank. The method proceeds by adding powdered material to the hopper, supplying water to the tube, and operating the auger to feed the powdered material into the tube, to mix it with water in the tube, and then to push the mixture out of the tube to the holding tank. For drywall texturing applications, the mixture may then be delivered from the holding tank under pressure to a spray nozzle. An apparatus for forming a mixture of powdered material and water includes a hopper, a holding tank, a tube intermediate the hopper and the holding tank, and an auger extending from the hopper into the tube. The auger feeds the powdered material from the hopper into the tube, mixes the powdered material in the tube with water introduced in the tube in order to produce the mixture, and then pushes the mixture out the second end of the tube to the holding tank. One embodiment includes a frame for supporting the foregoing components along with an air-driven motor for the auger, an air-driven pump for delivering the mud from the holding tank to a spray nozzle, a first air-driven stirring mechanism for stirring the powdered sack material in the hopper, a second air-driven stirring mechanism for stirring the mixture held in the holding tank, and suitable controls for regulating the production of mud according to the amount used.
