Crushing quarried aggregate is a key process stage of most quarries and when recycling demolition waste.  Effectively protecting the crusher from rogue tramp metal damage prevents production losses and repair costs. The wide range of available crushing technology enables the production of optimally sized aggregate.  Whereas Jaw and Gyratory designs commonly feature as primary crushers,…

Overband magnets

The Overband Magnet is one of the most commonly used magnetic separators.  Different designs are used in nearly all process industries and especially in mining, quarrying, recycling, and bulk handling applications. In operation, an Overband Magnet (or Suspension Magnet) sits above a conveyor carrying material.  As the material passes under the magnet, ferrous metal is…

Open and closed bullet magnet

A major UK mineral processing company has installed two large Bullet Magnets to remove tramp ferrous metal from dry reclaimed kaolin. After initial discussions, Bunting conducted controlled tests in the Redditch Centre-of-Excellence.  The reclaimed kaolin had a broad particle size range, with 95% below 250 microns.  Iron contamination was approximately 1000ppm (although it could peak…
