How the MBZ 304 N 500 magnetic drum turned metal waste in engineering into money (case study)
In a machining facility, mixed swarf was produced during turning parts made of bronze and cast iron. Although it contained valuable bronze, it ended up as ordinary waste – sold for a fraction of its real value. The reason was simple: without sorting, bronze and cast iron could not be effectively separated.
On an annual basis, it was “only” 2 tonnes of material from two machines. At first glance, not much. In reality, though, it meant money unnecessarily lost.
The customer was looking for a solution that would be simple, reliable, and economically viable even for smaller volumes.
The solution was a MBZ 304 N 500 magnetic drum with neodymium magnets, supplied including a hopper, frame, and vibratory feeder. The technology automatically separates ferromagnetic cast iron from non-magnetic bronze, smoothly and without operator intervention.
The result?
- clean bronze with a significantly higher buy-back price,
- minimal operating costs,
- payback in 1.5 years,
- and above all full control over the material.
The technology proved so effective that the customer ordered another identical unit after installing the first magnetic drum. That is the best reference.
MBZ 304 N 500 shows that even seemingly worthless metal waste can be a source of real profit – if you have the right solution.
