Specification material: stainless steel 304321316304 L, 316 L screen wire or low carbon steel galvanized wire. Structure principle: using the strong vibration caused by the vertical alternating medium (usually air or water) flow, the ore charge separately according to the relative density stratification and through the appropriate methods and heavy mineral, sorting in order to achieve the purpose of gravity separation process. Is a bigger coarse ore processing density difference is one of the most effective gravity separation method.

Product advantages: the most punching sieve plate used in coal washery are still in China, its through sieve rate is low, resistance is big, easy to plug holes, and the sieve plate welding, opening rate is as high as 70-80%, is a regular punching sieve plate opening rate of 1.5 times, because the opening rate is high, through screening ability, reduce the resistance of sieve plate pulsating flow, province of wind, water bed, improve the ability of handling the jig, thereby increasing the economic benefit of coal washing machine, for the upgrading of jig has broad prospects
