First, Different screening materials: The rotary vibrating screen can screen powder, granule, and slurry-like materials, while the direct discharge screen is mainly for powder materials (such as flour, starch, milk powder, additives, etc.).

Second, the working principle is different:
1. The working principle of the rotary vibrating screen: this series of screen machines use a vertical vibrating motor as the vibration source, and the weights (unbalanced weights) installed at the upper and lower ends convert the motion of the motor into a horizontal, vertical, and inclined three-dimensional motion , And then transfer this movement to the mesh surface. Changing the phase angle of the upper and lower weights of the motor can change the direction of movement of the raw material;
2. The working principle of the direct row screen: This series of screen machines use horizontal vibration motors on both sides as the excitation source. The vibration motor is placed on one side of the machine body. Motion trajectory. While the screen is completed quickly and reciprocally, the vibration force can continuously peel, break up and reorganize the material, so that the material can quickly pass through the network, and the material that cannot pass the network is screened according to the movement trajectory of the equipment. The upper discharge port is discharged to complete the screening process.

Third, the output is different: Compared with the three-dimensional rotary vibrating screen, the output of the direct-discharge vibrating screen will be larger, which is about 4 times that of the rotary vibrating screen. This is due to the open design of the inlet and outlet of the straight-line screen, so the output is relatively large;

Fourth, the screening accuracy is different: the direct-row sieve is mainly for the screening of flour and powdery materials, and the highest mesh number of flour-type powder materials is 140 meshes, so the highest sieve mesh number of the direct-row sieve is 140 meshes; and three times Due to the installation of the screen cleaning device, the element rotary vibrating screen can screen materials below 500 meshes at the highest.

Finally, the editor continues to emphasize: Whether it is a rotary vibrating screen or a straight row screen, they have their own characteristics and application areas. Therefore, when ordering screening equipment, we should describe in detail the mesh size, characteristics, output requirements, production environment, etc. of the materials to be screened, so that the vibrating screen manufacturer can recommend reasonable models.

Please provide some details: 1. Your material; 2. Mesh size; 3. Capacity per hour; 4. Material proportion.

The blocking phenomenon of linear vibrating screen is an important problem that various screening equipment manufacturers are committed to researching and solving. During the screening process, the blocking of the screen not only seriously affects the screening effect and efficiency, but also wears the screen to a large extent and reduces the screen. The service life of this product will not only cause inconvenience to users, but also increase unnecessary costs. If you want to solve the blockage of the direct-discharge vibrating screen, you must first know what are the reasons for the blockage of the vibrating screen?
Based on years of experience in vibrating screen production and manufacturing, there are two main reasons for the blockage of the screen, one is the various characteristics of the material itself, and the other is the structure of the vibrating screen.
After analysis, it is found that the reason for the blockage of the straight-line vibrating screen is mainly due to the large amount of fine-grained materials in the screened materials. The size of these fine particles is relatively close to the size of the screen hole, and it is easy to get stuck on the screen hole and cause blockage; The material is also relatively moist, and the wet fine particles will stick to each other and adhere to the screen surface, making the screening process difficult to complete. It is more difficult to change the properties of materials, so the solution to the clogging problem should mainly start with the structure of the vibrating screen and the structure of the screen.

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.
