The invention relates to a dry-mixed ceramic body powder homogenization production line, devices and method. According to the ceramic body powder homogenization production line, transfer bins in butt joint through a conveying belt are arranged between a stock bin and a hopper, and the homogenization devices are arranged on inlets of the stock bin, the transfer bins and the hopper. Each homogenization device is composed of a transition stock bin, a conveying pipe, a rotary dial wheel, a rotary shaft and a motor, wherein the conveying pipe is in oblique-angle through connection with the bottom of the transition stock bin, the rotary dial wheel is connected with and stretches into the pipe through the shaft end of the rotary shaft from the joint portion of the transition stock bin and the conveying pipe, and the motor is connected with the rotary shaft through a transmission mechanism. The conveying pipes can be driven by the motors to rotate around the stock bin through the rotary shafts, dry-mixed body powder is evenly conveyed into the stock bin, and the body powder is evenly distributed in compartments of the stock bin. The mixing state obtained before the body powder enters a skip car is consistent with the mixing state obtained after the body powder is dry-mixed, and it is guaranteed that the grain composition before the decayed powder enters the skip car is still the optimum value through multiple times of homogenization.
