The horizontal cylinder is equipped with a double shaft rotating reverse paddle, which circulates and stirs the materials along the axial and radial directions at a certain angle, so that the materials can be mixed quickly and evenly. Performance characteristics of the horizontal mixer the rotating speed of the reducer driven shaft and the structure of the paddle will weaken the gravity of the materials. With the lack of gravity, there are particle sizes The difference of specific gravity is ignored in the mixing process. The intense stirring motion shortens the time of one mixing, which is faster and more efficient. Even if there are differences in specific gravity and particle size of materials, good mixing effect can be achieved under the rapid and violent tossing and sprinkling of staggered mixing blades. High mixing uniformity and less residue, suitable for the mixing of more than two kinds of fertilizers, additives and premix.
