按照特定的网目尺寸分级物料是选矿过程中遇到的一个共同的问题。粗粒级(+14网目)用湿筛能够得到满意的处理,但大部分选矿厂在物料选别前要求粒度小于14网目。筛分存在很多缺点:由于堵塞的问题不能进行有效的分离;由于磨损,造成大量的维修工作;经
Grading the material to a particular mesh size is a common problem encountered in mineral processing. Coarse grading (+14 mesh) can be satisfactorily treated with a wet sieve, but most concentrators require a particle size of less than 14 meshes prior to material sorting. Screening has a number of disadvantages: an effective separation can not be achieved due to the problem of clogging; a large amount of maintenance work is caused due to wear;
