Drawer magnets consists of a row, or most commonly, rows of round magnetic tubes that are assembled into drawers. The tubes of the drawer magnet separators are aligned on alternating centers from the row directly above or below it. For protecting injection-molding machines, molds and dies, drawer magnet separators are very essential engineering products. The powerful magnets at the neck of the molding machine stop the flow of the tramp material directly into the machine parts. Drawer magnets are available in different styles to suit specific application needs.

How it works?
The product cascade in a zigzag pattern from row to row over the magnetic tubes as soon as it flows into the top of the housing. This methodology helps in the trap of maximum tramp metal because the product comes in direct and repeated contact with a magnet.

Ferrous metal while moving through the magnetic field is held to the tubes and separated from the product. The trapped metals are later cleaned from the tubes to prevent buildup and subsequent wash-off back into the product flow.

Features
Following are the features of the drawer magnets:
• The drawer magnets can be fitted simply in existing pipeline or outlet of various equipment like pulverizer, blenders etc.
• Generally each unit comprises of permanent magnetic grids mounted one above the other.
• For special applications there are system with multiple grids.
• The grids are easily removable for cleaning.
• Normally the ferrite or rare earth and NdFeB magnets are used in the drawer magnets.
• Certain types of drawer magnets handle a wide range of separation tasks in gravity conveying systems

Applications
The drawer magnets find their applications in following areas:
• Mining industries
• Pharmaceuticals industries
• Food processing industries
• Industries dealing with powdery substance
• Cement, gypsum and other types of small-scale industries.
