The straight-line screen is one of the screening equipment. The straight-line screen is

also called the straight-line vibrating screen, which is divided into single vibration

source and double vibration source. The bottom has a large flow outlet, and the inlet

and outlet are designed in the same vertical direction. The screened products quickly

pass through the screen, reducing the residence time of materials on the screen

surface, and the discharge is rapid, the processing capacity is large, and it is easy to

combine with the production line.

 

 
The vibrating motor uses two sets of eccentric blocks (unbalanced eccentric blocks) at

the upper and lower ends of its shaft to convert the rotating of the vibrating motor into

a multi-action force of horizontal, vertical, inclined and centrifugal superposition, and

then transmit this force to the screen surface. After the enters the interior of the

equipment, it is affected by the force of the vibration source and moves on an elliptical

trajectory on the screen surface, quickly and repeatedly completing sieving action,

while the vibration force can continuously produce the effects of stripping, crushing and

reorganizing the material, so that the material can quickly pass through the, and the

material that cannot pass through the screen is discharged from the discharge port on

the screen according to the movement trajectory of the equipment, and the sieving

operation is completed.

 

 
1. High screening efficiency: The screen can closely adhere to the material, reducing

the phenomenon of leakage, and the direct discharge screen vibration force for

screening, the material moves quickly on the screen surface, and can more quickly

complete the screening process, improving the screening efficiency.

2. Large processing: It has a larger feed port and a wider screen surface, which can

handle a large amount of material at the same time, especially suitable for assembly

line operations, can meet the processing needs of a large amount of material.

3. Strong adjustability: The phase angle and weight of the upper and lower eccentric

blocks of the vibration can be changed, thus changing the magnitude of the excitation

force and the trajectory of the material movement. At the same time, the vibration

force and amplitude can also adjusted to meet the processing needs of different

materials.

4. Simple structure and easy maintenance: It is mainly composed of screen box,

vibrator, screen net, spring and parts, the structure is relatively simple, easy to install,

and the vibrator adopts reliable design and high-quality parts, with a long service life,

and maintenance is also easy.

5. Good environmental performance: The equipment can be designed as a fully

enclosed structure, with strict sealing, no liquid leakage, no dust flying, which can

improve the working environment, reduce dust pollution, and meet environmental

protection requirements.

6. High degree of automation: It can achieve automated operation, can produce

continuously for 4 hours, reducing manual intervention, reducing labor intensity, and

improving production efficiency.
