随着工艺难度和环境保护要求的日益增高,在物料筛分过程中,湿式筛分的应用逐年扩大。其中,根据跳汰的作用机理和生产实践,研制和使用在水介质中进行湿筛的机械,是值得注意的动向。一、概况通常的湿筛(wet screen),筛网位于空气中,被筛物料或予先同水混成矿浆过筛,或由喷淋的水流冲洗过筛。后来出现的水中筛(hydraulic screen),则是在水介质中进行筛分的设备,筛网和筛上的物料层皆浸于水内。据报导,国外研制的水中筛,种类较 With the increasing difficulty of technology and environmental protection requirements, the application of wet screening has been expanding year by year in the material screening process. Among them, according to the mechanism and production practice of jigging, it is noteworthy to develop and use a wet sieving machine in water medium. First, the general situation of the wet screen (wet screen), the screen is located in the air, the sieve material or water mixed with the slurry into the previous sieve, or by the spray water flow sieved. Later appeared on the screen is (hydraulic screen), is in the water medium sieving equipment, screen and sieve material layer are immersed in water. It is reported that the water sieve developed abroad, more types
