Double magnetic drum separator (STMV2)

In brief

• The double magnetic drum separator (STMV2) was developed for recycling steel/aluminium chips from the machining of internal combustion engines.

• It is used in the mechanical engineering and metallurgical industries, multi-material machining workshops and metal waste recycling centres.

• A vibratory feeder supplies a first drum, then a second drum captures the remaining ferrous contaminants, even weakly magnetic ones.

Fields of application

Industrial applications of the STMV2 magnetic separator:

The STMV2 magnetic drum separator was specifically developed for recycling steel/aluminium chips from the machining of internal combustion engines.

• mechanical engineering and metallurgical industries,

• multi-material machining workshops,

• metal waste recycling and recovery centres,

• installations processing bulk metal chips or offcuts.

By removing impurities with a constant magnetic field, the magnetic separator improves the quality of the recovered aluminium and protects downstream operations.

Operating principles

Double drum operation:

The STMV2 operates according to a two-stage magnetic separation process to ensure optimum purity of the recovered product.

• A vibratory feeder distributes the flow onto a first magnetic drum, which acts as an agitator drum.
• The magnets generate a magnetic field that extracts a first portion of the ferrous material.
• The residual flow is then treated by a second drum, capable of capturing the remaining ferrous contaminants, even weakly magnetic ones.

This double drum system improves the overall efficiency of the magnetic separator and minimises the presence of any ferromagnetic impurities in the final product. A single drum separator is also available.

Operating recommendations

Optimising magnetic separator efficiency:

To make full use of the drum separator’s potential, it is essential to adapt it to the actual operating conditions:

• adjust the feed throughput for optimum exposure to the magnetic field,

• calibrate the deflection angles according to the ferrous contaminant content,

Correct sizing ensures optimum magnetic force for efficient and consistent separation over time.

Lenoir-Mec support allows the STMV2 to be precisely adapted to each industrial configuration.

Frequently asked questions

What application was the STMV2 separator developed for?

It was specifically developed for recycling steel/aluminium chips from the machining of internal combustion engines. It is also suitable for the mechanical engineering and metallurgical industries, multi-material machining workshops and metal waste recycling centres.

How does the STMV2 double drum work?

A vibratory feeder distributes the flow onto a first drum, which acts as an agitator drum and extracts a first portion of the ferrous material. The residual flow then passes over a second drum, which captures the remaining ferrous contaminants, even weakly magnetic ones.

What are the technical specifications of the STMV2?

It comprises a high-strength welded steel frame, a double drum fitted with industrial magnets, a vibratory feeder and two separate discharge chutes. External adjustments allow the magnetic force to be adapted.

How is the STMV2 adjusted to the processed flow?

The feed throughput must be adjusted for optimum exposure to the magnetic field, and the deflection angles calibrated according to the ferrous contaminant content. Adjustments are external and are made without stopping production.

Is there a single drum version of the STMV2?

Yes, a single drum separator, the STM, is also available in the range. The double drum STMV2 is designed to achieve higher purity of the recovered product.
