Working Principle
After the rectangular gyratory screen is started, the shaking body of the screen machine, that is, the screen box, reciprocates back and forth under the action of inertial force. The screen box drives the screen surface to shake periodically so that the materials on the screen surface make directional jumping movements together with the screen box.
During this period, materials smaller than the screen pore size fall to the lower layer through the sieve holes and become under-screen materials. Materials larger than the screen pore size are discharged from the discharge port after continuous rolling and jumping motion, thereby completing the screening work.

types of gyratory screen
According to the setting mode of vibration source, the gyratory screen can be divided into different types such as middle vibration type, down vibration type, double vibration source type, and single vibration source type. When choosing, it is necessary to comprehensively consider factors such as specific screening requirements, material characteristics, and production environment.
Different vibration modes
Middle-vibration square gyratory screen
Features: The vibration source of the middle-vibration square gyratory screen is usually located in the middle or near the center of the screen. This design allows the vibration force to be transmitted to each part of the screen surface more evenly, which helps to improve the screening efficiency and utilization of the screen surface.
Application: Suitable for occasions with high requirements for screening efficiency and uniformity, such as fine chemicals, food, and other industries.
Lower-vibration square gyratory screen
Features: The vibration source of the lower-vibration square gyratory screen is located at the bottom or below the screen. This design can reduce the impact of vibration on the upper structure of the screen machine and make the screen machine run more stably. At the same time, since the vibration source is at the bottom, the overall area of the screen surface can be better utilized for screening.
Application: Suitable for occasions with high requirements for screening stability or heavy screening materials, such as mining, metallurgy, and other industries.
different setting of vibration source
Double Vibration Source Square Gyratory Screen:
Features: The double vibration source square gyratory screen sets two or more exciters at different parts of the screen body. By changing the motion trajectory of the screen machine, the material has a relatively short pause state on the screen, thereby improving the screening capacity and accuracy. This type of screen machine usually has higher screening efficiency and a better net cleaning effect.
Application: It is widely used in occasions that require high-precision and large-volume screening, such as chemical, food, metallurgy, and other industries. Especially when the material particle size difference is large or multi-stage screening is required, the double vibration source square swinging screen performs well.
Single Vibration Source Square Gyratory Screen:
Features: The single-vibration source gyratory vibrating screen only sets one vibration source, and the vibration force generated by the vibration source drives the screen body to swing. This type of screen machine has a simple structure and is easy to maintain, but the screening efficiency and accuracy may be slightly inferior to the double-vibration source screen machine.
Application: It is suitable for occasions where the screening requirements are not particularly high or the material particle size distribution is relatively uniform. In some small production lines or laboratories, the single-vibration source square swinging screen is also widely used.
Features
Up to 5 times the output per unit area; accurate to 9 levels of separation, and the screening efficiency is as high as 95%-99%.
Each layer of screen mesh is equipped with a screen mesh anti-clogging cleaning device. The screening machine continuously cleans the mesh mesh under working conditions, and the mesh mesh has almost no clogging.
New technology
The large-scale electrostatic spraying process makes the equipment more beautiful, wear-resistant, and rust-proof.
Longer life
For flexible screening, the acceleration is 4-5 times lower than that of ordinary vibrating screens, and the service life is increased, thereby reducing maintenance costs.
Easy to operate
Network replacement is more convenient, simple to operate, and runs smoothly.
Environmental friendly
Fully enclosed structure, dust does not fly, and the screen machine has small vibration and low noise (less than 75 decibels), which meets environmental protection requirements.

FAQs
A: 10 layers (5 layers + 5 layers structure). We can also customize according to your requirements.
Compared with the traditional linear vibrating screen, the square swing screen can improve the screening accuracy by 3-5 times.
Gyratory Screen Linear Vibrating Screen
A: There is a fan-shaped material distribution device at the feed inlet, so that the material is more evenly distributed on the mesh surface when entering the screen box; the ball support plate can make the material fall evenly on the lower screen mesh surface during the screening process.
A: The motion trajectory of a single-source is a circular motion forward, left, and right. The first half of the double-source motion trajectory is a circular motion, and the second half is a reciprocating motion; it changes the material motion trajectory, increases production capacity, and solves the problem of clogging.
A: The function of double vibration source oil is to lubricate and protect bearings. We recommend that the oil filter should be replaced every 3-5 months.
A: It is preferably within 100 degrees.
A: We use specially customized oil-free and maintenance-free bearings.
A: (1) There is a screen fixing hook plate with a special structural design inside, and there is a rubber sealing strip on the pressure strip, which makes the screen and the pressure plate tightly connected. While protecting the screen, it prevents material leakage. (2) On the doors of the inlet and outlet, we are equipped with high-temperature resistant sponges. After closing the door, it is tightly connected to the sealing strips at the front and rear ends of the screen, without any gaps, effectively preventing mixing and material leakage. (3) A rubber sealing strip is attached to the mesh frame of the ball support plate to avoid friction between the screen and the ball support plate, extend the life of the screen, and help prevent mixing.
A: (1) For compact gyratory screens, the equipment can be directly loaded into a standard container. (2) For swing screens with hanging frames, we will disassemble the frame, motor and equipment box, and then load them directly into the container. After arriving at the customer’s factory, we will assemble it. Because the disassembled parts are easy to identify, the assembly is also simple. You can also refer to the drawings in the instruction manual. If necessary, you can also contact our sales staff for guidance.
A: The square gyratory screen adopts streamlined operation. Standard spare parts are in stock. After receiving the deposit, production can usually be completed within 7 working days. The specific delivery time depends on the order quantity.
