Continuous carbonization furnace for cans

Waste cans recycling and reuse, waste cans thin texture, large surface area, oxidation in the melting process burned serious, low metal recovery rate. There is a paint layer on the surface, which has a certain effect on the quality of aluminum alloy, and it is easy to produce smoke pollution by direct burning and melting. Through the waste recycler, waste station, waste company after the collection of waste cans in the form of damage, some have been broken into packages, difficult to separate, pre-treatment is difficult.

The key process of how to fully recycle cans is how to remove paint. West Germany Machinery provides cans continuous carbonization furnace, through the carbonization process to remove paint to achieve good results.

The continuous charring furnace for cans belongs to the environmentally friendly equipment, which can continuously charring cans without interruption, and all the smoke generated during charring is recycled, which is the equipment with higher efficiency of recycling cans at present.

Process Principle

Packed or flattened cans are first processed into 4cm pieces by shredder, and then added into the drum of continuous carbonization furnace by screw charger, because the furnace is almost a closed space, which meets the condition of anaerobic, so that the cans can be pyrolyzed and carbonized at a temperature of more than 400 degrees inside the furnace, and the flue gas generated is heated through the recycling pipeline and the flue gas purification system, and then burned by the burner in the main furnace, which achieves a reciprocal cycle of heating and carbonization. The carbonized cans are then heated in the main furnace by the burner, which achieves the effect of heating and carbonizing in a reciprocal cycle. At the initial carbonization preheating, the surface paint of the cans starts to carbonize and pyrolyze, and the pyrolysis of the combustible gas reaches the normal combustion, the gas cycle combustion and no fumes are discharged in the normal production state, and finally the pure aluminum is obtained.
