Zigzag Classifier - MZM and MZF Multi-Plex

  • Gravity classifier for sharp separations in the range of approx. 0.1 – 10 mm. 
  • Single- or multi-tube classifier. 
  • Low-maintenance and low-wear design.
  • Principle of operation

    Alpine offers zigzag classifiers in two different designs: MZM and MZF. Each design is available in a range of machine sizes from a single-tube to a multi-tube classifier. Ideal for sharp separations in the range d97 = approx. 0.3 - 10 mm.

    Throughputs can range from a few kg/h in the case of the laboratory classifier up to approx. 200 t/h for the industrial-scale multi-tube classifier. Classification takes place at every change in direction of the zigzag tube and permits an extremely high, steplessly adjustable precision of cut. The result is clean-cut fines or lightweight material, even under overload conditions.

  • Features
    • Maintenance-free and wear-resistant
    • Overload-proof
    • Insensitive to changes in the feed material composition

    As a result of these characteristics, once set, the classifying system can be operated over long periods without any supervision at all.

  • Applications
    • Oleiferous seeds: classifying systems for separating cracked soy beans or sunflower seeds.
    • Precious metals: the separation of copper, aluminium or lead from the insulation material of previously cut cable scrap. Dust removal from plastic granules, coke, chalk, fertilisers, bauxite, etc.
