Perfect Screening Process Needs Ordered Screening Orders

Vibrating screen is composed by the screening box, vibrating motor, absorber system and base plate etc.Screening box is composed by screen frame, sieve plate,liner, etc. Vibrating screen is mainly used in metallurgy, mining, coal, building materials, electric power, chemical and other industries. Especially in metallurgy industry,vibrating is the most widely used screening machine of blast furnace, coking plant, concentrator slot.

Illustration of our circular vibrating screen operation:

In screen grading, the material is separated mechanically on screen plates. Rolling bearings in vibrating screens are stressed by high, mostly shock-type loads. Moreover, the bearings, while rotating about their own axis, perform a circular, elliptical or linear vibrating motion. This results in high radial accelerations which additionally stress the bearings, and especially the cages, considerably. The operating speeds are usually very high. As a result, the bearing temperatures are up to 20 to 30 degrees Kelvin higher than in normal applications. In addition, considerable misalignments between the bearing locations and considerable shaft deflections have to be accommodated.

The screening order of vibrating screen in its applications commonly includes the following three points:

1, sequence method: screening from the fine to the coarse.

It is convenient to maintain and easy to observe the work of the screen layer sieve. In the process of screening the fine to the coarse, arrandeing in accordance with the screen surface to screen hole increased order.In addition, the uniaxial vibrating screen sieve can along the entire length of the screen surface respectively eduction.

2, overlapping method: screening from coarse to fine.

The shifters of the linear vibrating screen superimposes one by one in the process of its screening from the coarse to the...
