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.

Activated carbon has the key role of adsorption and purification. With the country now advocating environmental protection and sanitation, the application of activated carbon is more extensive. Many activated carbon manufacturers are also booming. Because activated carbon is more useful, the particle size is also different. Activated carbon screening machine is used for screening. However, in recent days, many manufacturers have reacted to the editor not knowing the daily precautions of the activated carbon screening machine, which has caused the service life of the activated carbon screening machine to be greatly shortened. Next, I will talk about the daily precautions of the activated carbon screening machine.
(1) Be sure to check whether the transportation support is removed when using it. Many manufacturers forget to remove the transportation support when receiving the goods, which makes the machine unusable, and even more serious damage to the machine will cause casualties to nearby people. Therefore, the transportation support must be removed before use.
(2) There is no hardware debris around 30 cm of the activated carbon screening machine. Because the screening machine may vibrate when it is turned on, if there are things around it will collide and cause damage to the machine or accidents, so there must be nothing around 30 cm.
(3) The inlet and outlet of the active carbon screening machine must use a soft connection, not a hard link. Because the screening machine will vibrate when it is running. If it is a hard link, it will vibrate back and forth and cause damage to the pipeline and equipment.
(4) Before each use of the machine, check whether the screen is loose or damaged. If it is loose and damaged, please replace it with a new screen in time to avoid ensuring that the activated carbon can be screened normally to achieve the screening effect.
(5) When the machine is running, check whether the machine has any special conditions, large noises or other abnormalities, and stop it immediately for inspection and maintenance.
(6) When the machine is in use, it must be turned on first, and then fed. It cannot be turned on after feeding. This will cause the material to accumulate and block the screen, thereby reducing the screening efficiency or failing to screen, and the screen will also be damaged. . When the sieving machine is stopped, it must first stop the feeding and other materials, after all the materials are sieved, and then go out through the discharge port, and then turn off the machine. Otherwise, the materials cannot be sieved and piled up in the sieving machine. Damage will greatly affect the service life of the screening machine.
(7) After the motor is used for a period of time, remember to add lubricant for maintenance.
(8) Before using the sieving machine, check whether the bolts and screws are locked in place. If there is any looseness, they must be tightened and the machine must be turned on after a certain period of operation to ensure safety, reliability and effectiveness.

When many manufacturers use stone grading linear screens, the improper use of the manufacturer has caused the machine to be damaged and unable to operate normally or other accidents. How to avoid such incidents?
(1) The stone grading linear screen should be placed horizontally and must be fastened and fixed.
(2) Check whether the screen is damaged or the tension is not enough. If it is damaged, replace it with a new screen immediately. If the tension is not enough, reinstall the screen to avoid the inability to screen the material or the insufficient fineness of the material.
(3) Check whether the parts of the stone grading linear vibrating screen are normal and whether the screws are tightened, and ensure that there is no looseness in the parts of each part, and ensure that the machine is used normally to avoid accidents.
(4) Ensure that the distance between the stone grading linear vibrating screen and the surrounding fixed objects is 30-50mm, and there should be no sundries in the middle to prevent machine damage and accidents caused by collision.
(5) When using the stone grading linear screen for the first time, the transportation support frame must be removed before opening the stone grading linear vibrating screen, otherwise it will affect the vibration work of the vibrating screen and cause machine damage and personal injury (many manufacturers will encounter this situation, so be sure to Pay special attention to this detail)
(6) Be sure to test the machine first, and then use it normally after confirming that it can be used.
(7) The linear sieve for stone grading should check whether the machine screws are loose at regular intervals, and if there are any abnormalities in other parts, repair them immediately.
(8) The machine must be fed evenly when using the machine, and the machine must be turned on before feeding to prevent the screen from being blocked and damaged. When hanging up, stop feeding and wait for all materials to come out before shutting down.
