二.Banana vibrating screen screen surface clogging

Screen surface clogging is another common failure phenomenon, mainly caused by too much material or material viscosity. The following are the common causes of screen clogging failure and the corresponding repair methods:

1Too much material:

When too much material is put on the screen surface, it will lead to the accumulation of material too thick, thus blocking the screen holes, so that the screening effect is reduced.

Maintenance methods:

Adjust the amount of material input: control the amount of material input, according to the processing capacity of the banana vibrating screen and the characteristics of the material to reasonably adjust the amount of input, to avoid excessive accumulation of materials on the screen surface.

2 The material viscosity is large:

Certain materials have high viscosity, easy to form a pile or adhesion on the sieve holes, resulting in screen clogging.

Maintenance fault method:

(1) water spraying to clean the screen surface: the use of water spraying to clean the way, through the jet water impact on the screen surface, to help separate and remove the material adhering to the screen holes.

(2) Regular cleaning of the screen surface: Regular cleaning of the screen surface, the use of appropriate tools or cleaning agents to remove the accumulation of materials or adhesion, to maintain the smoothness of the screen holes.

3Broken sieve mesh:

Prolonged use or impact of materials may cause the screen mesh to be broken, thus causing the screen surface to be blocked.

Repair fault method:

(1) Replace the broken screen mesh: check the condition of the screen mesh, such as cracks, breakage or wear and tear, replace the new screen mesh in time to ensure the integrity of the screen surface and normal use.

(2) Control the amount of material input: ensure that the equipment works within the normal operating load, avoid overloading. Reasonably control the amount of material input to reduce the excessive impact and pressure on the screen surface.

(3) Check material pretreatment: For materials that are easy to cause breakage, consider pretreatment, such as crushing, screening or removing oversized particles, in order to reduce the impact and pressure of materials on the screen surface.

(4) Regular replacement of screen surface: according to the recommendations of the equipment manufacturer, replace the screen surface regularly to avoid using aged and fatigued screen surface. In general, according to the use of the equipment and the characteristics of the material, you can make a corresponding screen surface replacement plan.

4、Inappropriate sieve hole size:

If the sieve hole size is not properly selected and does not match the particle size of the material, it will also lead to clogging of the sieve surface.

Maintenance fault method:

Adjust the sieve hole size: according to the particle size of the material and the screening requirements, choose the appropriate sieve hole size to ensure that the material can pass through smoothly and avoid the occurrence of clogging problems.

三.The banana vibrating screen noise is too large

Excessive noise may be caused by loose screen surface and support device, equipment imbalance and other problems. If the noise is too large, it will bring discomfort and harm to the working environment. The following are the common causes of excessive noise failure of banana vibrating screen and the corresponding repair methods:

1、Unbalanced vibration system:

The vibration system of the vibrating screen includes vibration motors, vibrators and other components. When the vibration system is unbalanced, it will cause the vibration of the banana vibrating screen to be unstable and produce noise.

Repair fault method:

Correct the balance of the vibration system: check the installation and adjustment of the vibration motor, vibrator and other components to ensure that they are balanced and properly installed. If there is an imbalance problem, you can make balance adjustment or replace the damaged components.

2、Poor contact between screen plate and screen frame:

Poor or loose contact between the sieve plate and sieve frame will cause the vibrating screen to produce friction and vibration during operation, causing noise.

Repair fault methods:

(1) Adjust the contact between the sieve plate and the sieve frame: check the contact between the sieve plate and the sieve frame to make sure that it fits tightly and has no looseness or gaps. Make adjustments if necessary and use appropriate fixtures to ensure good contact.

(2) Replacement of screen mesh: regularly check the condition of the screen mesh and replace it with a new one in a timely manner if it is deteriorated, worn or broken. Ensure that high-quality screen mesh that meets the specifications and requirements is selected and installed correctly.

3、Loose connectors:

Loose connectors such as bolts and nuts in the vibrating screen will produce noise and affect the normal operation of the vibrating screen.

Maintenance fault method:

Tighten the connecting parts: regularly check the connecting parts of the vibrating screen, such as bolts, nuts, etc., to ensure their fastening status. If there is any looseness, it should be tightened in time to maintain a stable connection.

4、The ground foundation is not smooth:

The foundation of the vibrating screen is not smooth, which will lead to resonance and vibration in the vibration process, and then produce noise.

Repair fault method:

Reinforce the foundation of banana vibrating screen: check the stability of the foundation of the vibrating screen to ensure that it is strong and flat. If there is a problem, you can take reinforcement measures, such as adding support, reinforcing the ground bolts, etc., to enhance the stability of the foundation.

To sum up, the common faults of banana vibrating screen include abnormal vibration, screen surface blockage and excessive noise of vibrating screen. For these failures, we can take the corresponding repair failure methods, which can effectively solve the faults and keep the banana vibrating screen running normally and working efficiently. By repairing the faults in time, we can extend the service life of the equipment and improve the production efficiency and product quality.

Banana sieve in daily maintenance mainly includes the following aspects:

For daily maintenance, the banana sieve should be cleaned regularly. Before the operation of the equipment, check whether there are debris accumulating on the screen surface, and after the end of the operation, remove the residual materials in a timely manner to prevent them from affecting the next use and damaging the screen. At the same time, check the fastening of the screen mesh to ensure that it is firmly installed and has no loose parts.

Regularly check the vibrating motor. This is the key component of the banana sieve, check whether the bolts of the motor are loose and whether the grease is sufficient. If the lubrication is insufficient, supplement the appropriate grease in time according to the requirements of the equipment. And pay attention to the operating temperature of the motor, if the temperature is too high, it may be a failure of the motor, and it needs to be shut down for inspection.

Also pay attention to check the screen box. Check whether there are cracks or deformations in the beams, side panels and other structural parts of the screen box. Because the banana sieve will produce vibration in the working process, these parts are prone to fatigue damage, and the problems found should be repaired or replaced in time.

In addition, it is also important to check the status of the spring and other supporting parts. Observe whether the spring is broken or the elasticity is weakened, if so, it needs to be replaced in time to ensure the normal vibration and operation of the banana sieve.
