Removal of tramp metals is an important issue in production and recycling of industrial rubber products. This problem can be solved by using a wide range of magnetic separators (guard magnets).

In case if it is necessary to extract metal from the «primary» product, where content of ferromagnetic admixtures is low and there is a possibility to stop the process for manually cleaning the magnetic separator, SMR magnetic grates are used. They can be installed in both vertical and inclined gravity flows, where rubber bits or soot are transported.

Other models of magnetic separators can also be used for extraction of ferromagnetic inclusions, i.e. SMBM modular drum separators.

Metal cord can be extracted from splintered tires by suspended magnetic separators SMPR & SMPA (manual cleaning system & self-cleaning correspondingly) which are installed above the conveyor belt, 350 mm. above the product burden. Ferrous metals are removed from the product burden by a powerful long-range magnetic field, when the product passes under the separator. Extracted metals are either held on a separator's sliding plate until cleaning procedure (SMPR model), or are removed automatically (SMPA model). One of the main advantages of the SMPR model is that those separators do not consume electric power, making the model indispensable for heavy-duty industrial tasks, where fire and explosion safety is essential.

Extraction of ferromagnetic inclusions can be also performed by magnetic pulleys (SMB model), which are installed instead of original conveyor's drive pulley. It is possible to produce a “twin-pulley” (exact copy of the original), to simplify installation and to upgrade the technological line without significant constructive revisions.

After processing of tires by pyrolysis or crushing, metal cord can be extracted from the product by SMBM or SMB separators. KSMB separators (mini-conveyor with magnetic pulley) are also widely-used for this application, their universality is explained by the easiness with which those separators can be added to existing technological lines.
