Circular Motion Vibrating Screen | Round Vibrating Sieve

In the production of sand and gravel, do you often encounter the rupture and perforation of the circular motion vibrating screen? If you want to solve it and don’t know how to deal with it, you can only replace the screen with a new one. This approach increases the user’s economic cost. Today, we will give you some solutions to the above problems.

The structure of the circular motion vibrating screen

The round vibrating sieve is composed of 9 parts: frame, left screen frame, right screen frame, polyurethane supporting beam, screen mesh, ore powder collecting bucket on the screen, ore powder collecting bucket under the screen, vibrating motor, and electrical control screen. The screen is installed on the supporting beam, and one screen is installed on the upper, middle, and lower supporting beams; the supporting beam is in contact with the reinforcing ribs on the screen to support the screen.

Working principle of circular motion vibrating screen

The circular vibrating sieve uses the inner eccentric shaft as the excitation force. The motor drives the eccentric shaft to rotate and then the vibrating screen is linked to make the circular motion trajectory of the up, front, down, and back so that the screened material is evenly and quickly slipped through the screen. Screening work.

Reasons for the rupture of the circular motion vibrating screen

1. Unreasonable design of screen reinforcement

If the circular motion vibrating screen is narrower than the supporting beam, the ribs are narrower than the supporting beam and do not completely match the supporting beam, which will cause the screen to rupture.

2. Failure to replace worn support beams in time

When the circular vibrating screen vibrates at high frequency, the sharpened, deviated and uneven support beams will continuously impact and wear the screen. Cause the screen to break and perforate prematurely.

3. Improper feeding amount

In the production process, if there are phenomena such as uneven feeding, excessive feeding drop, and excessive feeding flow, it will cause the screen to rupture and perforate.

4. Poor screen quality

The circular motion vibrating screen is made of polyurethane material, and it is mass-produced by the mold casting process. Due to changes in the proportion of ingredients, fluctuations in forming temperature, differences in the quality of operators, etc., the quality of the screen may be unstable, resulting in a decrease in the abrasion resistance, flex resistance, and bearing capacity of the screen.

5. Improper installation of the screen

Improper installation of the vibrating screen will increase the pressure on the screen, which will eventually lead to rupture and perforation of the part where the screen mesh is combined with the narrow reinforcement.

Measures to prevent the circular motion vibrating screen from breaking

1. Improve feeding conditions, reduce feeding gap and total amount, and feed evenly.

2. Sign a quality assurance agreement with the manufacturer to ensure the quality of the screen supply.

3. Improve the installation quality of the screen, so that the reinforcing ribs of the screen are completely consistent with the supporting beam to ensure the supporting area of the screen.

4. Replace the worn support beams in time.
