The main reason for the damage of the rotary vibrating screen during use
2023-09-09
Usually, the reason for the abnormal damage of the screen of the rotary vibrating screen is nothing more than the quality of the screen, the screen is installed, the reason of the vibration motor, the cause of the accumulation of clay and other reasons, the following are the reasons for these to parse: 1. Reasons for the quality of the screen The screen of the rotary vibrating screen is usually composed of two parts: the screening layer and the stress layer. The two layers are required to be tightly combined. If the pre-tensioning process of the screen is poor, when the stress layer at the bottom of the screen is tightened, the screen layer will not Tension, the throwing force of the material is greatly reduced during work, and the material cannot be discharged, which will cause premature damage to the screen; Solution: buy a screen with good quality and excellent workmanship. 2. Reasons for screen installation When installing the screen, the basic requirements for the installation of the screen cannot be met, such as insufficient tension of the screen, causing the screen to vibrate, resulting in breakage or damage along the edge of the screen or the edge of the edge; Solution: Strictly follow the instructions when installing the screen. 3. Causes of vibration motor When debugging the vibrating motor, some users will think that the material can move forward according to the experience of using the linear vibrating screen or single-axis vibrating screen, but this experience is not applicable to the vibrating screen. For example, the direction of the vibrating motor is wrong, and the material may roll backward At this time, the material moves forward much slower than normal, causing the material to stay on the screen for too long, or even unable to discharge, resulting in premature damage to the screen; Solution: When the sieve machine is running, press the stop button of the electric control box, and the vibrating screen will stop slowly at this time, observe the elliptical track formed by the small dots on the side plate when the vibrating screen is running, and roll to the discharge port to indicate the correct direction; Remove the vibrator shield, and check whether the eccentric weights are all rotated outward; Replace any two phase wires in the incoming power supply of the electric control box, sprinkle some sand on the screen, and the one with a faster sand discharge speed is the correct direction. 4. Reasons for clay accumulation When clay accumulates in the screen, it will cause the vibration amplitude of the equipment to be too small, it is difficult to screen under the condition of material stickiness, and the viscous force of the material cannot be effectively overcome, causing the material to accumulate on the screen and quickly damage the screen; Solution: increase the vibration amplitude; Use sprayed water to flush the screen and the material to reduce the viscosity of the material, but this method is only suitable for occasions where water is allowed; Adjust the angle of the screen at the end of the discharge port so that the angle is downward, which is beneficial for the material to be discharged by gravity, but it may cause pulp run; Change the mesh number of the sieve or adjust the flow of the sieve; Abnormal damage to the screen of the rotary vibrating screen not only increases the production cost, but also reduces the production efficiency, so the correct use of the rotary vibrating screen and the screen is particularly important.
