<p id="ProductOverviewIntro">With the&nbsp;sieve shaker AS 450 RETSCH have designed their first siever for 400 mm and 450 mm sieves which operates with a three-dimensional sieving motion. It can be used for dry and wet sieving. The optimized electromagnetic drive allows for an amplitude up to 2.2 mm which renders the separation process much more effective than with other sieve shakers of this type.</p>

		<img src="typo3temp/pics/8706f8eb69.jpg" width="200" height="200" border="0" align=right alt="" title="" />The sieve shaker&nbsp;AS 450 works with an electromagnetic drive that is patented by RETSCH (EP 0642844). This drive produces a 3D throwing motion that moves the product to be sieved equally over the whole sieving surface. The advantage: high stress capacity, extremely smooth operation and short sieving times with high separation efficiency.<br />
