Description

The product is linear motion Equal Thickness Grading Sieve. This product is characterized by reasonable structure, powerful excitation force, lower vibration noise, high efficiency in sieving and handling capability, easy to maintain and long service life. Its widely used in quarries, mines, building materials, electric power, coal and chemical sectors.
Working principle:
The operation of linear motion Equal Thickness Grading Sieve is the motor pass through the elastic coupling drives the eccentric exciter, as the material layer on the sieving surface becomes loose, finer aggregates fall down through the layers and separate through the sieve hole, shaking out the material that stick in the sieve. At the same time finer aggregate moves downward and discharge through the sieve holes. The material moves forward to achieve discharge.
1.The sieving surface consists of multi-section angle. The material at the feed end flows quickly and at the discharge end flows slowly. The material at the feed end become to be layered rapidly, the rough aggregates going up and the fine aggregates going down. The screening efficiency is 1.5-2 times than ordinary sieve. The vibration sieve of this structure is especially suitable for handling the material that with high content of required material.
2. The machine is optimizing designed by finite element analysis, ensuring the strength of it and making the load as low as possible. At the same time, by abating the beam stress, it will connected with the high strength bolt which is good at self-locking and stability at the lateral panel. It can avoid the additional load caused by welding stress efficiently, and enhance the fatigue life of the machine. 
3.The exciter uses the dilute oil circulating lubrication system. The drain plug is magnetic. Its also very convenient to adjust the clump weight.
4.The electric circuit is inverter brake connected. The vibrating sieve can turn off the machine safely and steadily, letting the sieve bed skip the sympathetic vibration area quickly and increases its service life.
5.The screen mesh has two forms, briquette type and module type, the module type is for card installation.
6.The lateral panel of the sieve bed is cut and drilled completely by high precision CNC cutting machine, to ensure the accuracy of the shape and the drill hole.
7. The lateral panel has no weld, extremely avoiding the cracking of lateral pane
l.8.The flitch and angle stiffener are installed at the area of the lateral panel that bears larger stress, in order to effectively increase the strength of the lateral panel. All joints of the sieve bed are connected with the high strength steel structured bolts in order to avoid the stress caused by the welding.
9.Maximizing the use of screen mesh area and the number of available pore.
10. With the polyurethane screen mesh, the machine has the advantages of light weight, long service life and easy replacement.
11.The screen mesh has two kinds of structure, inlaid type (module type) and platen type. We can choose the most suitable sieve plates according to different materials and working conditions.
