Wagner Magnete GmbH & Co. KG
Extensive developments with permanent magnets and their applications followed. In 1985 Wagner introduced the first non-ferrous separator in a major trade fair.Moreover, the electronics with continuously improved control possibilities for the clamping and metal detection have become more and more significant. It marked the beginning of a new generation of metal detectors that are now characterized with high sensitivity, suppression of interferences and operating comfort.

The Beginning
When Georg Wagner founded the company of G. Wagner & Co. KG in Heimertingen in 1935 he set his company the aim of becoming specialist in magnetic clamping.Numerous patent rights in this field within only a short period of time proved his competence.
Innovative
Various slewing devices, combinations for clamping pole faces and capacitor-controlled demagnetising units revolutionized the magnetic clamping technology.We have thus been reliable pillars of the industry from the beginning.
Competent
New products in the field of iron separation from bulk goods followed. Wagner built rotating magnetic drums and magnetic pulleys with automatic iron discharge and in 1953 the first magnetic belt separator which were important components of today's recycling methods.

Particular is Our Standard
In a continually changing market you cannot rest on your laurels of the past. In the year 2005 we can proudly look back on 70 years of business history. During this period of time the name Wagner Magnete became the epitome of quality, safety and reliability. It is our obligation for the future to offer the best solution to our customers.Our daily new challenge is the high demand on quality and innovation: certainly not the easiest and cheapest way, but for our customers the most inexpensive one.
News:Investment in ECS Technologies
Eddy current separators (ECS) are used in the recycling industry for recovering non-ferrous metals. By means of rotating, high-energy neodymium magnet systems, they generate fast-alternating magnetic fields with high intensity. As a result, non-ferrous metals such as copper and aluminium are flung out of the bulk solids flow.
Wagner Magnete is currently investing in the development of new technologies and has significantly increased the production capacities.
At IFAT, Wagner Magnete GmbH based in Heimertingen (Allgäu) presented a new eddy current separator with a high-frequency rotor system that achieves a nominal speed up to 7000 rpm. The new high-frequency eddy current separator combines various advantages. It is optimally suited for the recovery of extremely small non-ferrous metal particles from a particle size of 0.5 mm. On account of the high rotor speed, the number of poles can be reduced, and accordingly larger and stronger neodymium magnets can be used. With the relatively large poles, a large field depth, a long-term effect and a high energy density can be achieved.
On account of the current successes in the “nonferrous separators” division, another assembly facility was built in 2016, as a result of which the assembly area for final assembly of the non-ferrous separators will be tripled.
“In addition, in the course of the building activities, the company is doubling the assembly space for the final assembly of the overbelt magnets and suspended magnets,” says Managing Director Wolfgang Wagner.
The pilot plant facility is also being renewed too. A new 500-m² test center facility for eddy current separators and magnetic separator technology has been erected.
In the recycling industry, different technologies are used to generate magnetic fields. Eddy current separators with large working widths are becoming increasingly important, such as for example in the recovery of aluminium in the processing of waste timber and bulk waste, where very large streams of material must be handled.
“All our large standard machines for waste timber reach a speed of 3000 rpm. That also applies to the latest Wagner technology that has a working width of 3 m”, explains Thomas Zrenner, Wagner Sales Manager responsible for eddy current separators, magnetic separators and metal detectors.
'The magnet rotors of eddy current separators have an extreme length to diameter ratio. This leads to the generation of different natural frequencies. Safe and durable operation at these high speeds requires precision manufacturing of the magnet rotors, which also have to be extremely well balanced. An important precondition for safe operation at very high rotor speeds is an absolutely reliable control system. It is capable at all times to control the magnet rotors – even in the event of temporary or longerterm power outage. “In the case of power failure or an emergency shutdown, our control system controls the rotors – reliably to their standstill. Moreover, at all times it is able on restoration of the supply power to control the rotor up to nominal speed,” explains Thomas Zrenner.
