<p>A wear plate retainer (10) having upper and lower layers (10B, 10A). The lower layer is formed of a relatively soft, shock-absorbent material. The upper layer is formed of a relatively hard, impact and abrasion resistant material. A plurality of magnets (20) are embedded in the upper layer to removably magnetically retain a wear plate (12) atop the upper layer. A pair of pole pieces (22, 24) are positioned on opposed sides of each magnet and embedded in the upper layer. The pole pieces extend above the magnet, protecting it from impact forces. The pole pieces focus the magnetic field forces emanating from the magnet. The magnets are arranged in rows, with adjacent poles of adjacent pairs of magnets in adjacent pairs of the rows having alternate polarity. The rows are parallel to one another and extend transversely to the direction (16) in which material (14) flows across the wear plate.</p> |
