Screening machine capacity and efficiency of screening interdependence

        With the growth of sieving time, the screen surface less easily sieve particles; left most "difficult sieve particles," grain size of the material is close to a mesh

size of these particles. These hard particles through the sieve sieve, takes a long time, screening efficiency increases more slowly. Therefore, the length of the screen surface

only within a certain range, to improve screening efficiency work, can not be over-extended length of the screen surface, otherwise the Screen machine bulky structure,

achieving the desired effect.
   
        Screening machine processing capacity and screening efficiency are interdependent, to a reasonable selection. Thus, the width and length of the screen surface to combine

consideration in order to determine a reasonable proportion of the width and length parameters. In general, the length and width of the screen surface ratio of 2 to 3. For

coarse materials, screening, screen surface length is 3. 5 ~ 4m; For medium fine grade material screening, screen surface length of 5 ~ 6m; materials for dehydration and

sculping screening, sieve surface length of 6 ~ 7m; sand vibrating screen of the screen surface can be shorter, the final screening sieve surface should be longer.
   
        All kinds of screening machine width and length to form a series of screening machine type spectrum. Crusher manufacturers believe that screening should pay attention to

the correct choice is very important.
