The dry vibrating screen used in mining and industry is an important screening equipment, mainly used for screening and classifying dry ore, sand, coal, and other materials. Here are some common dry vibrating screens used in mining and industry and their characteristics:
Circular vibrating screen:
Features: The eccentric block in the vibrator is used to rotate to generate centrifugal force to vibrate the screen box. By adjusting the mass of the eccentric block, the amplitude of the screen can be easily changed.
Application: Widely used in coal, metallurgy, mining, electric power, building materials, chemical industry, and other industries.
Features: It is driven by dual-vibration motors. When the two vibration motors rotate synchronously and in opposite directions, the exciting forces generated by their eccentric blocks cancel each other out in the direction parallel to the motor axis and overlap into one in the direction perpendicular to the motor axis. The resultant force is so that the motion trajectory of the screen machine is a straight line.
Application: It is suitable for screening and classifying various powder and granular materials, and is widely used in mining, coal, metallurgy, building materials, electric power, light industry, chemical industry, and other industries.
What is a circular vibrating screen?
Circular vibrating screen is a common screening equipment, mainly used for continuous screening, impurity removal, and classification of materials. The following is a detailed introduction to the circular vibrating screen:
What is the working principle of circular vibrating screen?
The working principle of the circular vibrating screen is based on the excitation force generated by its vibrator, which causes the screen body to perform circular motion in the vertical direction. After the material enters the screen, it undergoes continuous jumping motion due to the impulse transmitted from the screen box. In this process, materials smaller than the screen hole fall to the lower layer through the screen hole and become under-sieve materials, while materials larger than the screen hole are discharged from the screen surface after continuous jumping and become over-sieve materials, thus achieving the goals of screening and classification. Purpose.
Structural features of Circular vibrating screen
1. Screen box: The screen box of the circular vibrating screen is the main part of screening materials and consists of the screen frame, screen mesh, lining, and other components. The screen can be made of appropriate materials and specifications according to the particle size and screening requirements of the material.
2. Vibrator: The vibrator is the core component of the circular vibrating screen. It generates exciting force to make the screen box move in a circular motion. The vibrator usually includes components such as an eccentric block and a main shaft. The mass and rotation speed of the eccentric block can be adjusted to change the amplitude and vibration frequency of the screen box.
3. Vibration damping device: In order to reduce the impact of the vibrating screen on the foundation, a vibration damping device, such as a rubber damper or spring damper, is usually installed at the bottom of the screen box.
4. Support device: The support device is used to support the screen box and vibrator. It usually adopts a steel structure or welded structure and has high strength and stability.
What is a Dewatering screen?
Dewatering screen is a kind of screening equipment widely used in various industries. It is mainly used for continuous screening, impurity removal, and classification of materials. The following is a detailed introduction to linear vibrating screens:
working principle of Dewatering screen
The linear vibrating screen uses the excitation force generated by the vibration motor to make the screen body perform linear reciprocating motion in the horizontal direction. After the material enters the screen machine, it undergoes continuous jumping motion on the screen surface due to the impulse transmitted by the screen box. In this process, materials smaller than the screen hole fall to the lower layer through the screen hole and become under-sieve materials, while materials larger than the screen hole are discharged from the screen surface after continuous jumping and become over-sieve materials, thus achieving the goals of screening and classification. Purpose.

Screen box: The screen box of the linear vibrating screen is composed of a screen frame, screen mesh, lining plate, and other components, and is the main part of screening materials. The screen can be made of appropriate materials and specifications according to the particle size and screening requirements of the material.
Vibration motor: The vibration motor is the power source of the linear vibrating screen. The exciting force it generates is transmitted to the screen box through the force transmission plate, causing the screen box to produce linear reciprocating motion.
Vibration damping device: In order to reduce the impact of the vibrating screen on the foundation, a vibration damping device, such as a rubber damper or spring damper, is usually installed at the bottom of the screen box.
Support device: The support device is used to support the screen box and vibration motor. It usually adopts a steel structure or welded structure and has high strength and stability.
