Since the aggregate market is popular nowadays,more and more stone size is needed,customer not only pursue the crushing machinery but also demand the varies kind of different sizes,such as 0~3mm,3~5mm,5~10mm and so on.
The main factors affecting the screening effect are as following:
1.The humidity of material: material humidity is greater, the greater the more viscous,easy to plug into a corporation or sieve, is not conducive to screening.
2.Material particles about small, more difficult to screen;
3.The particle size range: particle size is close to the boundary of the more difficult when the diameter of separation, whereas in the gap between the bigger diameter of easy separation;
4.In addition, parameter screening equipment also has a tremendous effect on the sieving effect.
In 19 century,people are use the fixed screen,it is the most simple screening equipment(vibrating screen), welding by the steel bar,usually used for the primary screening and final ones,it is apply the stone own gravity which is drop on the mesh in order make the screening go run,it doesn't need the power,the installation angle is about 35~60,the fixed screen can be feeding by train box(compartment or platform),dump truck,loading machine. Granularity is the sieve composition, has a decisive influence on the screening process, can be seen on the screen in practice, is smaller than the mesh particles more easily through the sieve, sieve size to 3/4, although the screen size is small, but difficult to sieve through. Slightly larger in diameter than the sieve hole particles, often shut out the screen, prevent fine through. When the increase in material 'to sieve grain' content, a productivity increase rapidly, or, in certain circumstances to maintain productivity, higher efficiency can be obtained. Granular material maximum allowable size and mesh size between certain proportional relationship is not clearly defined, hongxingly 2.5~4 times the maximum grain size shall not be greater than the aperture size.
