How to clean the limestone standard inspection sieve?
Clean according to the actual situation. The remaining dust particles should be scrubbed with a soft brush first. Special residues should be washed with dilute acetic acid. If it is a metal frame or copper wire mesh test sieve, a special cleaning agent should be used.
The specific steps for cleaning the test sieve are as follows:
1. Turn off the power of the standard inspection sieve.
2. Loosen the fixing nuts at the two corners, remove the upper cover of the test sieve, and remove the sieve frame to be cleaned.
3. Use a vacuum straw and a rag to clean the remaining parts of the standard test sieve.
4. Use compressed air to clean the particles and powder on the screen. If the particles or powder are stuck in the screen holes and cannot come out, you can tap the screen lightly.
5. Install the small hole screen, large hole screen and upper cover in order.
6. Pack up the tools used when cleaning the standard inspection sieve and clean it.
Please note! When cleaning, do not press too hard on the grid to remove stuck particles, nor should you use sharp objects to clear blockages. To prevent the mesh from breaking.
The difference between swing screen and rotary vibrating screen:
1. The working principle of the swing screen is different from that of the rotary vibrating screen.
From the perspective of running trajectory, the swing screen is a nonlinear inertial vibrating screen, and its basic rotary motion is similar to manual screening. The material is evenly dispersed on the entire screen surface from the center to the outer edge, thereby spreading in the axial direction in a spiral motion. The fine particles thus complete the entire screening process. The rotary vibrating screen is a screening machine that performs three-dimensional circular motion, so the production sites required by the two screening machines are also different.
2. Different production output
If you want large output, it is recommended that you use a swing screen. If you want high precision, you need to use a rotary vibrating screen. This is because the area of contact between the screen surface of the swing screen and the material is large, while the usable area of the rotary vibrating screen is smaller. A larger contact part between the screen surface and the material will effectively increase the product throughput, while a small contact part will effectively improve the screening accuracy.
3. Screening accuracy is different
Since the rotary vibrating screen performs three-dimensional motion, and the operation mode of the swing screen determines that the effective screening area is doubled, the screening accuracy can reach more than 95%.
4. Impact on raw materials
There is no doubt that the rotary vibrating screen uses the principle of vibration to screen materials. Due to the vibration, the appearance of the materials will be destroyed. Therefore, many granular crystalline and brittle materials are not suitable for screening by the rotary vibrating screen, such as chicken essence and rotary vibrating screen. MSG, sugar, cooked food, etc. The swing screen has a slight elliptical swing motion, does not use vibration, has little impact on the raw materials, will not damage the material shape, and further improves the material output rate.
5. There is a big price difference between the swing screen and the rotary vibrating screen.
As a standard product in screening equipment, rotary vibrating screens have been produced for decades. The technology is mature and the supporting equipment is complete, so the price-performance ratio is very high. As a new product, the swing screen is relatively complicated to make and the supporting equipment is not perfect, so the price is generally several times higher than that of the rotary vibrating screen.
Can the rotary vibrating screen be changed to my local voltage?
YES
Usually the common voltages in China are 380V, 50HZ, three-phase electricity and 220V, 50HZ, single-phase electricity.
If your local voltage is different from that in China, you can communicate with the sales staff in time before production starts.
We will provide a reasonable solution based on the characteristics of the product and your local voltage.
Here are some common voltages for reference only:
380V, 50HZ, three-phase
220V, 50HZ, single phase
220V, 60HZ, single phase
415V, 50HZ, three-phase
How effective is the linear vibrating screen in sand screening?
How effective is the screening?
The linear screen has a large screening area and high processing capacity, which can meet the output requirement of 6 tons per hour, and can screen out fine sand with a mesh size of 1.5mm.

How durable is the equipment?
The screen mesh and grid frame of the linear screen are made of stainless steel 304, which has good corrosion resistance and long life. The overall material of the inclined screw conveyor is carbon steel. After appropriate anti-corrosion treatment, it can meet the needs of long-term use.

How to adjust the inclination angle of the inclined screw conveyor?
The inclination angle of the inclined screw conveyor can be realized by adjusting the height of the screw conveyor support points on the support frame to adapt to different production needs.
Can a rotary vibrating screen filter liquids?
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.
Analysis on the causes of screen clogging of rotary vibrating screen
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.
