Tumbler screening machine is a kind of low-frequency rotary vibrating screen which imitates manual screening.The material has a movement similar to manual operation,so as to achieve the purpose of screening.With the screening accessories,it can get more ideal screening effect.To meet the large out put,high-density sieving of the manufacturers.It is the most effective simulation of artificial sieving movement (sieving precision,efficiency,service life is 5-10 times than the common cylinder sieve),for the processing of all the fine and ultra-fine powder and special materials,particularly suitable for materials which are difficult to classify.
