The thermal break aluminum pulverizer is a high-speed hammer mill used for the further size reduction of prepared thermal break aluminum profiles and aluminum-plastic material after pre-cutting, primary shredding or initial crushing.
A high-speed rotor drives the hammers to repeatedly impact, deform and further reduce the prepared material. The hammers, liner plates and screen grate work together to produce smaller, screen-controlled pieces and improve the exposure of PA66 insulation strips, rubber seals and other attached materials.
Long profiles, complete window frames, bundled scrap and oversized material are not suitable for direct pulverizer feeding. These materials may first require pre-cutting or primary processing by a thermal break aluminum shredder.
Material requiring initial hammer crushing may first pass through an aluminum profile crusher before entering the finer pulverizing stage. Whether separate crushing and pulverizing stages are required depends on the incoming profile dimensions and expected output size.
After pulverizing, a magnetic separator can recover exposed screws, hinges, steel brackets and other ferrous components from the aluminum-rich material stream.
Screening and material spreading may be added to classify the output and provide more uniform feeding. An eddy current separator may then recover conductive non-ferrous metals from a suitable non-metallic material stream after ferrous metal removal.
An eddy current separator does not normally separate mixed aluminum, copper and other non-ferrous metals into individual high-purity products. Additional sorting equipment may be required according to the expected recovered fractions.
The thermal break aluminum pulverizer can form part of an aluminum profile crushing plant with pre-shredding, crushing, pulverizing, magnetic separation, screening, airflow sorting and dust collection selected according to the material and processing objective.
Position of the Pulverizer in the Process
The thermal break aluminum pulverizer is a later-stage high-speed hammer mill for prepared material that has already been cut, shredded or initially crushed. It is not intended for long profiles, complete frames or dense bundles. Its role is further size reduction and improved liberation when the required particle condition cannot be achieved by the primary stages alone.
When a Separate Pulverizing Stage Is Justified
A separate pulverizer should be evaluated only when the project requires a smaller screen-controlled fraction, additional exposure of PA66 strips or other attached material, or a specific feed condition for downstream separation. If a single crusher already produces the required size and liberation, adding another hammer stage may increase power use and wear without sufficient benefit.
Data Required Before Selection
Confirm the incoming size from the previous machine, aluminum-to-plastic ratio, steel contamination, moisture, target particle range, hourly capacity and downstream sorting method. Screen selection and hammer configuration should be based on representative processed material rather than unprepared profiles.
