1. No need to add lubricating oil, no rotating parts;
2. The vibrating screen has simple structure, convenient maintenance, long service life, and greatly reduced failure rate;
3. The vibrating screen vibrator uses the principle of resonance, the double mass body works in critical resonance state, the required driving power is small, there is no large starting current when starting, and the noise is low;
4. After the vibrating screen vibrator is started, the amplitude can reach the stable working value instantaneously. When it is stopped, its amplitude will disappear instantly, and it is allowed to start and stop directly under the rated voltage, current and amplitude.
5. Both the excitation and amplitude of the vibrating screen can be adjusted, and the particle size of the product under the screen can be controlled by changing the excitation force of the screen.
6. While vibrating the sieve body, the sieve bars of the sieves will also vibrate relative to each other, so that the gaps between the sieves are not easy to be blocked.

When the shaftless screw conveyor conveys sludge and other materials with a certain viscosity, the sludge basically contains some other types of debris and stone-like stones. If you use a common type of screw conveyor, it is easy to damage the spiral blades. Or debris is wound on the spiral shaft, which affects the later use of the equipment.
The inclination angle of the screw conveyor has an impact on the productivity and power consumption of the screw conveyor. The conveying capacity of the screw conveyor will rapidly decrease with the increase of the inclination angle. At the same time, the inclination angle of the screw conveyor will also affect the material. The conveying effect.
The maximum inclination angle of the shaftless screw conveyor is 30°. What is the conveying volume per hour (that is, how many cubic meters are conveyed per hour, depending on the specific gravity of the material, what is the effective conveying length you need to provide (the distance from the discharge port to the feed port or special space requirements), tilt What is the angle?

1. The bucket elevator adopts a plastic hopper to reduce the hardness of the hopper and reduce the impact damage rate during the picking and unloading process of the bucket elevator.
2. Minimize the occurrence of material overflowing the hopper of the bucket elevator, and adopt a closed-end deep bucket.
3. In the bucket elevator, belt drive is used as much as possible, chain drive is used less to reduce the appearance of material being squeezed, and the arc base is used at the base to reduce the residual amount of material at the bottom.

1. The quality of the screen is an important factor that causes the screen to break too quickly. If the material of the screen does not meet the screening requirements of the material, the screen will be damaged quickly.　　
2. The screen generally has an upper screen layer and a lower stress layer. The two layers are required to be closely attached. If the pre-tensioning process of the screen is poor, when the stress layer at the bottom of the screen is tightened, the screen If the stratification is not tightened, the vibration distance of the screen when the screen is working is too large, and the part in contact with the screen frame cannot be compressed, which is also one of the reasons for the rapid damage of the screen. In addition, the tension of the screen is not enough, which causes the screen to vibrate, which is usually broken or damaged along the edge of the screen or at the edge bead.
3. The feeding problem of materials. Because the vibrating screen is constantly feeding, if too much material is fed at a time, it will hinder the normal movement of the material on the screen, which will not only easily loosen the screen, but also greatly reduce the processing capacity of the material. Giving a large amount of materials at one time will cause the load of the motor that is in unbalanced operation to increase suddenly, which not only easily damages the screen, but also easily damages the vibrating motor. Therefore, the materials must be fed evenly when placing the materials. In the feeding method with strong impact force, the vibrating screen must be equipped with a buffer hopper. The direct impact of the material on the screen will consume the exciting force generated by the vibration source, which is more likely to cause the screen to be damaged.

1. Before operation, check the motor, transmission and protective devices, and confirm that they are intact and effective. The bearing seat, eccentric block and machine seat bolts should be fastened firmly.
2. The vibrating table should be equipped with reliable locking clamps. The concrete tank should be locked when vibrating, and the concrete template must not vibrate unconstrained on the vibrating table.
3. The vibrating table cable should be worn in the electric pipe and pre-embedded firmly.
4. Before operation, check and confirm that there is no leakage of lubricating oil, and that the oil temperature and transmission device meet the requirements.

Since the vibrating screen may break, fail to start, or run out of deviation and other large jumps during long-term use, do you know why these situations occur?
1. The vibration force of the vibrating screen is too large
If the power of the vibrating screen does not match the model during operation, it may cause a large displacement or jump in the use time.
2. Improper installation
If the ground is uneven or improperly installed during the installation of the vibrating screen, it will cause excessive vibration, so it is recommended that you pay more attention when installing it.
3. The anchor bolts are loose
Due to the long-term operation of the vibrating screen, the anchor bolts will be loosened under long-term vibration, which will cause the vibrating screen to produce greater vibration. In view of this situation, it is recommended that you regularly check and tighten the anchor bolts.
4. The hardness of the damping spring is too large
The damping spring is a component that connects the base of the screen and the frame of the screen. It has a buffering effect. If it is too hard, the buffering effect may not be achieved, causing the equipment to run off.
5. The rotation of the motor is inconsistent with the power
If the vibrating motor of the vibrating screen is worn or damaged, when the user replaces the motor, the rotation of the motor is inconsistent with the power, which may cause the vibrating screen equipment to vibrate violently.
