The market application of ultrafine powder is becoming increasingly widespread, and the corresponding production process requirements are becoming increasingly strict. The requirements for the particle size and particle segment distribution of finished powder are becoming increasingly clear, and the low oxygen content of powder has become a new important indicator for high-end materials. Therefore, there are new standards for the process control of powder preparation. In addition to the preparation process, it is also necessary to control the particle size to avoid residual large or uneven particles. When parts are made by powder forming, ultrafine powder often gives the parts excellent properties. The finer the powder, the larger the adsorption, agglomeration, and specific surface area, the more obvious the fluidity, the higher the probability of oxidation, and the explosion characteristics will be displayed; This also makes it more difficult to separate large particles, separate small particles, control particle fragments, and reduce oxygen content, and the requirements for screening technology and screening systems are becoming increasingly high; Different metal or alloy powders have different physical properties, and a simple screening machine alone cannot solve the process problem of screening cutting-edge materials.

1. During the process of forced screening, the material will not be affected by mesh blockage or pasting, which will affect the passing speed.
2. The screening system and brushing system of the forced screen can be separated and become a regular rotary vibrating screen after disassembly.
3. The forced screening machine is mainly used for dissolving, loosening, and filtering materials.
4. During the operation of the brush and screen machine, the material can be evenly spread on the screen, without gradually squeezing the material to the edge of the screen due to the transfer of the brush, thereby affecting the material passing speed.
5. For materials with clumps and high viscosity of fine powder or slurry. The hardness of the clump is not very high, but it can be crushed by hand.
6. The brush material for forced screening is polymer material, and the brush can freely lift and move away from the screen to adjust the pressure on the screen and facilitate changing the screen.
7. The brush of the brush sieve can be adjusted arbitrarily between different material thicknesses (0-8cm) to adjust the pressure and contact area between the brush and the sieve.
8. The speed of the brush sieve can be increased from 0 rpm, and the brush rotates smoothly and uniformly without significant shaking.
9. The part of the brush screen that comes into contact with the material can be made of carbon steel, stainless steel, or plastic.
10. The vibration motor of the forced screen and the motor of the brush are powered independently and can be started and stopped separately.

The reasons that affect the screening effect of the vibrating screen are:

1. The influence of the properties of the vibrating screen surface and its structural parameters on a certain material, the productivity and screening efficiency of the sieve are determined by the size of the sieve hole. The productivity depends on the width of the screen surface, which has a high productivity. The screening efficiency depends on the length of the screen surface, which has a high screening efficiency. The general aspect ratio is 2. The larger the sieve area (i.e. the ratio of the sieve aperture area to the entire sieve surface area), the higher the unit area productivity and screening efficiency of the sieve surface. The larger the mesh size, the greater the productivity per unit sieve surface and the higher the screening efficiency.

2. The physical properties of the screened material include the particle size composition, humidity, mud content, and particle shape of the material itself. When the content of fine particles in the material is high, the productivity of the sieve is also high. When the humidity of the material is high, the screening efficiency generally decreases. However, the larger the sieve size, the smaller the impact of moisture. Therefore, for wet materials with high moisture content, in order to improve the screening process, it is generally possible to increase the sieve size or use wet screening. Materials with a high mud content (when the mud content is greater than 8) should be screened through wet screening or pre washed.

The linear screen is not unfamiliar to most users. You can easily purchase the technical specifications you need when purchasing. However, the layout of the linear vibrating screen's discharge port is often neglected and shipped to the site after purchase. There will be a variety of thorny problems. Among them, the layout of the discharge port is a common problem. If there is no way, the discharge port will be removed and installed again. Today, I will explain the discharge port for everyone. What are the layout forms
(1) Multi-layer discharge port: The multi-layer linear sieving machine screens a material into a variety of materials with different particle sizes. For example, a four-layer linear sieving machine has a total of five discharge ports. The correct arrangement is on both sides There is a discharge port in the middle of the two discharge ports, and the front and back discharge ports must have a certain appropriate distance. This has the advantage that the belt conveyor or manual feeding is more convenient when discharging, and the distance is not too close to affect the feeding.
(2) Single-layer discharge port: For some special cases, the material discharge port needs to have a certain angle (forward discharge). The discharge port of this kind of linear screening machine is rare, and the material flowability is better. The material is convenient, but a small number of customers have requirements for this discharge method, so users should consider thoroughly before ordering. To
(3) Dewatering outlet: Some users use linear sieving machine for dehydration. The water outlet and the material outlet need to be arranged reasonably. The outlet is generally distributed at the bottom of the linear screen, and skirts need to be added around it. It is conducive to the left and right direction of the water pipe to discharge the water, so the user should determine the water outlet in advance when determining the purchase of the linear dewatering screen, so as to avoid unnecessary troubles.

Silicon carbide is corrosive, so when sieving chemical raw material silicon carbide, the use of ordinary carbon steel or stainless steel may corrode it and affect the quality of silicon carbide. So when sieving silicon carbide, which kind of vibrating screen can we choose to screen it? According to the material characteristics of silicon carbide, we recommend to you-plastic vibrating screen
The plastic vibrating screen is the same as the ordinary rotary vibrating screen with a vertical vibrating motor as the vibration source. The screen and the parts in contact with the silicon carbide are made of plastic material. After the silicon carbide is poured into the screen, it is subjected to the excitation force of the motor. According to the difference between the size of the screen mesh and the silicon carbide materials, the silicon carbide smaller than the mesh size quickly enters the lower layer, and the impurities in the silicon carbide larger than the screen mesh are left on the screen surface and discharged at the upper discharge port. So as to complete the entire silicon carbide screening process.
