Circular vibrating screen refers to an inertial vibrating screen whose vibrating body of the screen machine, i.e., the screen box, has an approximate circular motion trajectory. This type of vibrating screen is also known as a single shaft vibrating screen. The vibration force generated by the vibration source of a circular vibrating screen is an inertial force with a positive change in direction around a fixed axis, and its essence is a centrifugal force formed by the rotation of an eccentric mass around a fixed axis.

Explanation of what matters are involved in the use and maintenance of circular vibrating screens

The working principle of a circular vibrating screen is that after the screen is started, the vibrator of the screen drives the vibrating screen box to perform a directional jump motion together. During this process, materials smaller than the aperture of the screen surface fall through the screen aperture to the lower layer, becoming undersize materials. Materials larger than the aperture of the screen surface are discharged from the discharge port through continuous jump motion. Complete the screening work.

The circular vibrating screen is mainly composed of a screen box, a screen mesh, a vibrator, and a vibration damping spring. It is characterized by high screening efficiency, scientific and reasonable structure, high overall strength and stiffness, stable operation, durability, low noise, and convenient maintenance.

The following items are explained about the use and maintenance of circular vibrating screens:

1. The vibrating screen should be equipped with electrical protection devices.

2. At the initial stage of operation of the vibrating screen, check the anchor bolts at least once a day to prevent looseness.

3. When the rotation direction of the motor does not meet the requirements, adjust the phase sequence of the power supply.

4. After the vibrating screen has been running for 1500 hours, the bearings should be inspected and replaced immediately if there is serious damage.

Circular vibrating screen is widely used, with a single layer and double layer structure on the screen surface. It is widely used in various industries such as coal, mining, electric power, building materials, light industry, and chemical industry for dry and wet classification of various granular and small pieces of loose solid materials.
