The chemical composition of the mixer dust is complex, including FeO, CaO, S, P, C, etc.; the physical properties are also unstable, the particle size varies, and it is sometimes dry and sometimes wet. In addition, due to the high viscosity of the dust, dust clumps often form in the air inlet pipe, causing the pipe to be blocked.
