Single-Axis Vibrating Screen

Single-axis Vibrating Screen

The trajectory of the single-axis vibrating screen is a circle. There are 17 specifications in the whole series, which can be used for auxiliary or independent screening operations in mining, coal, electric power, construction, chemical, and other departments for dry classification of medium-grained materials. The sieving machine with rubber sieve plates is particularly effective in classifying coke materials.

The single-shaft vibrating screen has a simple structure, convenient maintenance, reliable operation, high screening efficiency, screen penetration, and good performance;
The installation forms include the hanging type and seat type. It is a multi-layer material screening device. The number of layers is single-layer or double-layer, and can be customized according to the required number of layers;
The transmission form is divided into left and right, and the sieve plate has punching and weaving (including a rubber screen).

Structure Type of Single-Axis Vibrating Screen

The single-axis vibrating screen for mine is composed of a screen box, vibrator, spring, and other parts. There are two types of support: suspension support and seat support, suspension support, and the screen surface is fixed on the screen box; the screen box adopts a welded structure, which is firm and reliable and is suspended or supported by springs. Driven by the pulley to rotate at high speed.

On the main shaft of the vibrator, except for the eccentricity in the middle part, an eccentric wheel with adjustable eccentric weight is installed at both ends of the main shaft, or an eccentric wheel is also made at both ends of the shaft, and then an ellipse wheel with adjustable core weight is installed. The disc with eccentric weight is installed on the main shaft and rotates with the main shaft to generate centrifugal inertial force so that the screen box that can vibrate freely will vibrate in an approximate circular track; the distance between the eccentric weight and the center line of the bearing is the excitation eccentricity.

Working Principle of Single-Axis Vibrating Screen

The motor drives the vibrator through the V-belt, and the transmission shaft rotates at a certain speed, so the eccentric shaft and the eccentric mass of the eccentric wheel generate inertia. Under the action of inertia, the screen box moves in an approximately circular arc, and the spring supports the screen box. The impact force is transmitted to the foundation by the sieve during operation. A damping device is installed horizontally on the spring seat to limit the lateral swing of the sieve and reduce the vibration amplitude of the sieve when it resonates.
