Chip and Swarf Pretreatment Line
Crusher, screen, dryer, preheating and feeder to prepare aluminium chips before melting
Overview
What it is and where it works
A line that prepares machining chips and swarf for remelting: a crusher breaks long and nested chips, a screen and magnetic separator remove oversize and iron, and a rotary dryer drives off oil and coolant at a temperature below melting, and a preheater and feeder charge the chips into the furnace. Dry chips are safer to charge and lose less metal in the furnace or go on to briquetting.
- Safety
- Moisture-laden chips are a major explosion hazard in melting furnaces
- Dryer duty
- Volatilises oil and coolant without melting the chips, to cut melt loss
- Dryer type
- Rotating drum with flights that shower the chips through the hot gas

Buyer questions
Frequently Asked Questions
Is a centrifuge enough or do I need a dryer?
A centrifuge removes most of the free coolant; a dryer is needed to drive off the remaining oil and water before the furnace. Residual values depend on your chips and should be confirmed by a test.
Can the dryer treat painted or coated scrap?
Chip dryers are meant for uncoated material; coated scrap such as UBC needs a decoating (delacquering) unit, which is a different process.
