WAH Continuous Horizontal Single Shaft Mixers consist of a cylindrical mixing drum vessel with an inlet at one end of the mixing drum, an outlet at the opposite end and a venting spout, a full material mixing shaft, two drum closing end plates that carry flanged end bearing assemblies complete with integrated air or gas-purged shaft seals, and a drive unit complete with power transmission.
Ploughshares or inclined blade-type shovels rotate as mixing tools in a special arrangement on the mixer shaft inside the drum vessel. The result is a turbulence in the mix that constantly involves all the product particles in the mixing process. The formation of dead spots or slow-movement zones in the mixing drum is prevented ensuring precise mixing. In some cases, to obtain the desired mixing effect, separately driven high-speed choppers can be installed.
