The rectangular vibrating sieve, also known as a rectangular vibrating screen or rectangular separator, is a type of vibrating screen used for the efficient separation of bulk materials into different particle sizes. It features a rectangular shape, which allows for larger screening areas and higher capacity compared to circular vibrating screens. Here is some information about rectangular vibrating sieves:
Working Principle:
The working principle of a rectangular vibrating sieve is based on the vibration of the screen box. The sieve deck is mounted on springs or a suspension system that allows it to vibrate freely in a linear motion. As the material is fed onto the sieve deck, the vibration causes the particles to move across the sieve surface. The larger particles are retained on the screen, while the smaller particles pass through the openings in the mesh. This separation process is achieved by the combination of gravity and the mechanical forces generated by the vibrating motion.
The linear vibrating screen is mainly composed of a lower basement, the shock absorbing spring, a vibrating box, the net frames with wire sieve, two vibrating motor and a dust cover. Different parts of the linear vibrating screen play different roles in the process of screening materials, but they are coordinated and completed together.
Sieving and Separation
The material particles encounter the openings (mesh or perforations) on the screen surface. Particles that are smaller than the openings (undersize) easily pass through and fall through the lower discharge outlet. On the other hand, particles larger than the openings (oversize) cannot pass through and are carried forward towards the discharge end.
Feeding Distributor
There is a feed inlet on the dust cover, and a regulating valve is set in the feed inlet to distribute the material evenly to the entire screen surface, so that the screen can be fully utilized to achieve the best screening effect.
Net Frame with wire sieves
The net frame is the fixing device of the screen, and it is the part where the material size particles are separated. The net frame device must not only have sufficient strength to support the screen, but also ensure that the screen is flat and firmly fixed in the screen machine. At the same time, attention should be paid to the tightness between the screen and the screen to prevent material leakage.
Vibrator motors
The vibrating motor is the heart of the vibrating equipment. The reasonable selection of the vibrating motor model is very critical. The power source of the linear vibrating screen is composed of two horizontal vibrating motors with identical specifications and models. When the vibration force is too large, it will not only seriously damage the overall structure of the machine, but also cause the materials on the screen surface to jump too high and far away from the screen surface, especially for those relatively light materials to form a floating phenomenon, which will shorten the residence time of the materials on the screen surface and reduce the mesh contacting times, which is not conducive to the materials passing through the screen and affect the passing rate; In the selection of vibration motors, under normal circumstances, a vibration motor with a higher vibration force is selected as the power source, and the optimal vibration force of the two vibration motors is selected by adjusting the overlapping amount of eccentric blocks at both ends of the vibration motor, so as to meet production needs.

Sorting & Grading
a. High Screening Efficiency: Linear vibrating screens can achieve high screening efficiency due to the linear motion of the material and the relatively large screening area.
b. Accurate Particle Separation: The linear motion and precise control of vibrations result in accurate particle separation into different size fractions.
c. Low Power Consumption: These sieves consume less power compared to other types of vibrating screens, making them energy-efficient.
d. Low Maintenance: With fewer moving parts, linear vibration sieves are easy to maintain, reducing downtime and operational costs.
e. Wide Range of Applications: Linear vibration sieves can handle a broad range of materials, from fine powders to coarse particles, making them suitable for diverse industries.
Linear vibrating screens are widely used in various industries such as mining, coal, metallurgy, building materials, refractory materials, light industry, chemical, and more. They are commonly used for screening and grading of bulk materials and are particularly useful for processing large quantities of materials.
2. Can linear vibrating screens be used for wet materials?
Yes, linear vibrating screens can be used for both dry and wet materials. For wet materials, the screen deck is often equipped with water sprays to aid in the screening process and prevent material build-up.
3. How to select the right linear vibrating screen for specific applications?
To choose the appropriate linear vibrating screen, consider factors such as the material type, particle size, desired capacity, moisture content, and the specific application requirements. Consulting with a reputable manufacturer or supplier can help in making the right selection.
4. Can linear vibrating screens be customized for specific needs?
Yes, many manufacturers offer customizations for linear vibrating screens to meet specific requirements. Customization options may include screen size, screen deck number, material of construction, and additional features such as dust covers or protective coatings.
