对再生砂进行有效脱水, 洗过的沙子被送到陡坡上, downward inclined screen surface at the feed end of the 砂石脱水筛 to achieve rapid drainage. A pool of water forms in the transition area as material builds up on the slightly upward inclined surface. Two counter-rotating vibratory motors create a linear motion at an angle to the screen surface. 这种快速运动加速了固体的向上和向前, forcing the liquid and small organic fibers to drain through the sand and through the screen surface. The sand is conveyed up the screen toward the discharge by this linear motion. 屏幕的上坡, 还有一个排水堰, 形成了一个深沙床作为过滤介质, allowing material much finer than the screen openings to be retained. Water and sand that pass through the screen’s surface are typically recycled back to the source or captured again in a Hydrocyclone system. 这 allows the process to attain recovery rates well over 90% while yielding a clean, 干砂菠菜网最稳定正规平台_最全菠菜网大全. 在砂分离系统中, the water held in the sand contains a small amount of organic material that acts as food for bacteria. 当水在脱水筛中从沙子中抽出时, 它拖着一部分细小的纤维, 哪个出口有水. 这 yields a cleaner sand without the use of additional fresh water. Screens can be fitted with a Derocker to remove oversize and tramp material from the bedding sand before it is dewatered. 这个Derocker可以移走大块的石头, 塑料, wood and other debris that can be problematic if it ends up in the sand bedding.
