SCRAP & DROSS GUIDE
Selecting a Rotary Scrap or Dross Recycling Furnace for Aluminum Recovery
Aluminum scrap, dross and contaminated returns do not behave like clean ingot. A recycling furnace must be selected around the material’s metallic content, geometry, coatings, contaminants, moisture, batch size and desired product. The complete process should include preparation, melting, separation, holding and final casting.
Define the incoming material
Identify scrap source, alloy range, piece size, bulk density, coatings, oils, organics, iron, moisture and expected variation. Representative sampling is essential because recovery equipment cannot correct an uncontrolled feed stream.
For a useful equipment review, record the material condition, required capacity, operating schedule, utilities, loading and discharge method, layout limits, safety responsibilities and acceptance criteria. Dynamo’s metal recycling furnaces provide a product path, while the final configuration must be based on verified process data and site engineering.
Separate scrap melting from dross recovery
Loose or contaminated scrap and aluminum-bearing dross require different process objectives. Scrap melting aims to convert prepared metal into a controlled bath, while dross processing focuses on separating recoverable metallic aluminum from oxide-rich material.
For a useful equipment review, record the material condition, required capacity, operating schedule, utilities, loading and discharge method, layout limits, safety responsibilities and acceptance criteria. Dynamo’s scrap processing machines provide a product path, while the final configuration must be based on verified process data and site engineering.
Set a defensible recovery target
State the method for weighing and sampling inputs and outputs. Account for moisture, nonmetallic material, skimmings, salt or flux where applicable, heel changes and metal remaining in equipment.
For a useful equipment review, record the material condition, required capacity, operating schedule, utilities, loading and discharge method, layout limits, safety responsibilities and acceptance criteria. Dynamo’s metal recycling furnaces provide a product path, while the final configuration must be based on verified process data and site engineering.
Plan emissions and residue handling
Paint, oil, coatings and fines can change exhaust and air-treatment requirements. The project must also define dross, oxide, filter dust and other residue routes under applicable environmental and safety rules.
For a useful equipment review, record the material condition, required capacity, operating schedule, utilities, loading and discharge method, layout limits, safety responsibilities and acceptance criteria. Dynamo’s scrap processing machines provide a product path, while the final configuration must be based on verified process data and site engineering.
Coordinate downstream production
Molten output may enter a holder, alloying station, ingot line or sow casting system. Match batch timing and discharge method to downstream capacity so the recycling furnace can run predictably.

Frequently asked questions
What information is needed to select this equipment?
Start with alloy, feedstock or product form, hourly and peak demand, operating temperature, schedule, utilities, material movement, controls, maintenance access and the required performance test. Representative samples and drawings reduce assumptions.
Why should upstream and downstream equipment be reviewed together?
A machine can meet its own rating while the total line still misses production. Preparation, melting, holding, transfer and casting capacity must be balanced so one stage does not repeatedly starve or overload another.
How should suppliers be compared?
Use the same duty, boundaries and acceptance method for every proposal. Compare usable output, metal recovery, energy, maintenance, controls, installation, training, spare parts and lifecycle support rather than a single headline specification.
Discuss your furnace or metal-recovery project
Share the alloy, material stream, required output, operating schedule and plant constraints. Axiom Machinery can help organize the requirements and connect the project with Dynamo Furnaces.
