脱水振动筛是煤泥脱水作业的用设备，广泛适用于煤泥回收，压滤隔粗、过滤隔粗，其他细物料的脱水、回收等工艺条件。洗沙场脱水筛的应用域非常的广泛，比如矿山、化工、冶金、煤炭、建材等一些行业，在他们的日常生产工作中都可以用到这个脱水筛。脱水筛是适用于粒度在0.074-5mm、含水量小于7%、无粘性的各种干式粉状物料的筛分，很大给料粒度不大于10mm。
　　为什么洗沙场要配套使用脱水筛呢？要知道经过洗砂机洗过的沙子并不是很干净，沙子含泥量大且过湿（含水量大），并不符合对砂子泥含量低标准高的生产需要。因此需要配置脱水筛，砂石经由洗砂机清洗，再经过脱水筛二次水洗砂、水力分级、脱泥、脱水，实现合理的粒度配比，将含泥量降到0.7%以下。

Dewatering vibrating screen is the equipment used in the dewatering operation of coal slime. It is widely used in the technological conditions of coal slime recovery, press filtration, filter separation, dewatering and recovery of other fine materials. The application of dewatering screen in sand washing yard is very extensive, such as mine, chemical industry, metallurgy, coal, building materials and other industries, which can be used in their daily production work. Dewatering screen is suitable for screening dry powder materials with particle size of 0.074-5mm, moisture content of less than 7%, and no stickiness. The large feed size is less than 10mm.

Why should the dewatering screen be used in the sand washing yard? It is important to know that the sand washed by sand washer is not very clean. The sand contains a large amount of mud and is too wet (with a large water content), which does not meet the production needs of low and high standard mud content. Therefore, it is necessary to configure a dewatering screen. The sand and stone are washed by a sand washer, and then washed by secondary water, hydraulic grading, desliming and dewatering of the dewatering screen, so as to achieve a reasonable particle size ratio and reduce the sludge content to less than 0.7%.
