Aluminium flotation line
The main machine in this aluminium flotation line is a bi-directional separation drum. This drum separates the mixed aluminium fractions brought in from the shredder plant. The source material consists of engine blocks which were shredded to a fraction size of 120 mm. The granulation of the material lies between 4 and 120 mm. The installation has a capacity between 15 and 20 tonnes per hour.
The working of the bi-directional separation drum is bases on the dense medium separation principle. The liquid used for the flotation has a density of 3,0 kg/dm³. This technique allows us to separate Alu – sg 2,755 kg/dm³ – and heavier materials present in engine blocks, like copper, lead and zinc, in an economic way.
The aluminium flotation line consists of the following elements:
- Feed hopper on weighing cells
- Conveying systems
- Magnetic speration with overbelt magnet
- Bi directional separation drum
- Drum washer with recuperation zone for the flotation liquid and washing zone to clean the products
- Medium recuperation
- Medium storage
- Water treatment
