Mixer for the Preparation of Various Types of Mixtures


New designs of mixers with mixing members, made in the form of rods are proposed. Intensification of the process of preparing building mixes in mixers with rods working bodies is possible due to the division of the material into numerous streams, their immediate association and the subsequent repetition of these operations. The mixer comprises a horizontally installed onto supports body with a semi-cylindrical bottom, into the end walls of which is mounted a shaft with mixing members, made in the form of rods situated radially and in staggered order on the shaft.

Innovative Aspect and Main Advantages

  • Simple construction of mixing organs;
  • Preparation of the dry and semidry mixtures, mortar, concrete and mixtures with inclusions;
  • Reduction of the mixing duration by 20 – 30%;
  • Reduction of the use of binder by 15 – 20 %;
  • Reduced of energy by 2 – 3 times.

Areas of Application

  • Preparation of mixes;
  • Building;
  • Metallurgy;
  • Animal industries;
  • Agriculture;
  • Pharmacology;
  • Food-processing industry.
