The conveying distance of a screw conveyor can be determined based on a variety of factors, including the design and specifications of the screw conveyor, the nature of the material being conveyed, the conveying angle, and the support structure used. Generally speaking, the conveying distance of screw conveyors can range from a few meters to hundreds of meters.

For short conveying distances (within tens of meters), the screw conveyor can usually be installed directly on a support structure, and the motor drives the screw to rotate to transport the material along the pitch direction of the screw.

For longer conveying distances (hundreds of meters), more complex designs and configurations may be required. A common practice is to segment the screw conveyor into sections, usually 10 to 20 meters in length, and then connect the sections through bearings and couplings. This reduces stress and vibration on the entire system and makes maintenance and installation easier.

In addition, in order to support longer distance transportation, additional support structures may be needed, such as pipes, support frames, etc. The design and installation of these structures also need to be considered on a case-by-case basis to ensure the stability and safety of transportation.

It should be noted that the conveying distance of the screw conveyor is too long, which may affect the conveying capacity and efficiency. For longer conveying distances, the fluidity and accumulation of materials also need to be considered to avoid clogging and accumulation.

Therefore, the specific maximum conveying distance of the screw conveyor needs to be evaluated and determined based on the requirements of the actual application and engineering design.

Yes, rotary vibrating screens can be used to filter liquids. The rotary vibrating screen is a commonly used solid-liquid separation equipment that uses rotation and vibration to screen solid particles or solid particles suspended in the liquid from the liquid. It can be widely used in liquid-solid-liquid separation and solid particle screening processes in chemical, food, pharmaceutical, environmental protection and other industries.

The working principle of the rotary vibrating screen is to separate liquid and solid particles through the mesh holes on the vibrating screen. While vibrating, the liquid will flow through the sieve holes, but the solid particles cannot pass through the sieve holes and are screened out. The screen mesh of the rotary vibrating screen is usually made of stainless steel or other corrosion-resistant materials to ensure its durability and corrosion resistance.

When using a rotary vibrating screen to filter liquids, it is necessary to select the appropriate screen aperture according to the properties and requirements of the liquid to ensure the required solid-liquid separation effect and screening accuracy. In addition, it is necessary to select appropriate rotary vibrating screen equipment according to the flow rate and processing capacity of the liquid to meet production requirements.

As we all know, when the rotary vibrating screen is in normal operation, the characteristics of the screening material and the factors of the material will appear large and small, and the screen holes with different shapes are blocked.
The clogging factors are as follows:
1. The water content inside the material is too high;
2. The interior contains a large number of particles that are close to the separation point;
3. Generate a lot of static electricity;
4. Among the materials with fibrous materials;
5. More flake particles block the screen holes;
6. Because there are many fine-grained materials in the screening materials, the fine-grained size and the size of the sieve are relatively close;
7. The sieved materials are relatively moist, and the moist fine particles will stick to each other on the screen surface;
8. The size design of the hole pattern is unreasonable, the thicker or thicker the particles are stuck;
Among the several clogging factors listed from the editor, most of the sieved materials are irregular in shape, so the clogging factors are also various.
Solution:
In order to effectively prevent the clogging of the rotary vibrating screen, the countermeasures should be taken against the above clogging factors:
1. First of all, the screened materials must be accurately identified and judged.
2. Check whether the rotary vibrating screen equipment is in a smooth state, and regularly check the screen and drain port.
3. Pay attention to adjust the eccentric block angle of the vibration motor, and deal with it according to the actual situation of the material and the precise requirements of the screening.
4. When the moisture of the material is more than 8%, wet screening is required, and the screen surface and screen hole should be selected accordingly.
5. For materials with more flake particles, it is necessary to change the particle size and size of the crushing process of the materials.

1. Motor: See if the line is broken and crimped, whether the wire is not long enough, whether the motor current is correct, whether the lubricant is injected too much in a single operation.
2. Abnormal sound appears: see if the ring screws are tightened, whether the ring is fully fitted, whether the machine is stable, whether the spring is broken or cracked, the body collides with other hard objects, whether the motor alloy steel screws are loose, Whether the discharge port is in contact with other foreign objects.
3. Raw materials and discharge: observe whether the motor runs in the wrong direction, the angle between the upper and lower eccentric blocks is too large, and the device of the upper and lower eccentric blocks is wrong.
4. Fine mesh is easy to break: whether the raw material directly impacts the mesh surface, whether the fine mesh is tightened, whether the coarse mesh has been damaged, or the rubber pad has been worn thin.
5. The outlet of the stainless steel frame is cracked: whether the overweight pipe is connected or the heavy object is hung, whether the ring is locked evenly.

Manual sieving method: i.e. sieving with a hand-held standard sieve, which requires constant tapping during sieving and has the disadvantage of being time-consuming and labor-intensive. The minimum size of 75 microns
Mechanical sieving method: the standard sieve according to the size of the sieve holes stacked into a sieve tower, installed on the vibration sifter, without manual participation in the sieve, can be automatically sieved, sieve size of the minimum 75 microns, there is a certain amount of noise.
Air jet sieving method: the use of negative pressure so that the air flow method so that the sample is sieved The disadvantage is that only a layer of sieving, sieving volume is small, the maximum sieving volume of 30 grams, sieving size of 20 microns minimum.
Sonic sieving method: the use of sound waves generated by the vibration of the sieve, sieve layer 8 layers, sieve size of the smallest 5 microns, the disadvantage of the relative volume of mechanical sieve instrument is slightly larger.

Should I use an ultrasonic rotary vibrating sieve or a straight sieve to sift flour?
First, let us understand the working principle and advantages of ultrasonic rotary vibrating screen. Ultrasonic rotary vibrating screen is a device that uses ultrasonic waves and vibration force for screening. Through the action of ultrasonic waves, it can cause flour particles to vibrate at high frequencies on the screen, thereby achieving rapid and uniform screening. Ultrasonic rotary vibrating screen has the advantages of high screening efficiency, high screening precision, and simple operation. It can effectively remove small impurities in flour, and at the same time, it can also achieve precise control of the size of flour particles, making the quality of flour more stable.
However, in-line screening also has its unique advantages. The inline screen is a device that performs screening through gravity and the inclination angle of the screen. Its working principle is relatively simple and its operation is relatively convenient. The inline screen can achieve classification and screening of flour particles by adjusting the inclination angle of the screen. This screening method is suitable for situations where the size requirements of flour particles are not very strict. The screening efficiency of the straight screen may be relatively low, but its structure is relatively simple and the maintenance cost is low.
In summary, the choice of ultrasonic rotary vibrating screen or straight row screen should be decided according to the specific screening needs. If you have strict requirements on flour quality and particle size, and want to achieve efficient and accurate screening, then the ultrasonic rotary vibrating screen is a better choice. It can improve screening efficiency and ensure stable flour quality. If the flour particle size requirements are relatively loose and you want to save on equipment maintenance costs, then a straight screen may be more suitable. Of course, in practical applications, you also need to consider factors such as the price of the equipment, maintenance costs, production scale, etc., and comprehensively weigh all factors to choose the screening equipment that best suits your needs.
