1. The thickness of the screen frame plate
Some manufacturers will choose some thinner materials when making, so that it will be easy to break during use, which will affect its normal use.

2. The welding is not firm
When the screen frame is not firmly welded, it is easy to break during use, so the equipment will not run smoothly during operation, which will affect the screening effect.

3. Exciting force is too large
Although the excitation force can be adjusted, the user may adjust the force too much, which may cause a break during operation. Therefore, it needs to be adjusted appropriately, not too large.

1. Rubber material
Rubber seals are widely used, but they are rarely used in the food and chemical industries, because the rubber itself has certain pollution components to the material, and the rubber is easy to fall off during screening, which will seriously affect the quality of the material, but its price Low and strong wear resistance, users should install suitable seals according to the different requirements of materials when purchasing a vibrating screen.

2. Polyurethane material
Polyurethane materials are usually used in mine screens and feeder linings. Rotary vibrating screens are rarely used as seals to prevent dust. However, seals made of polyurethane materials are also more common in mining environments. Polyurethane is more Silicone and rubber materials are more wear-resistant, but the hardness is higher.

3. Silicone material
The color is milky white, and its softness is good, so it has good dust-proof effect in the sealing material, and has good dust-proof effect for screening starch and mud powder in high-polluting environments. Dahan manufacturers recommend that users should try their best when choosing a vibrating screen. Choosing silica gel material as the best choice for dust prevention, although the cost is higher, the actual value is much higher than the other two materials (especially in the food and pharmaceutical industries).

1. When working outdoors, the circular vibrating screen should be built with a sun screen or awning.
Long-term exposure to the hot sun will not only make the machine easy to wear and aging, but also make the temperature of the circular vibrating screen too high and unable to work normally, affecting the efficiency and quality of the screening, and severely will cause the vibrating screen components such as vibrating motor And other damage.

2. For circular vibrating screens that work indoors or in mines, attention should be paid to the adjustment of indoor temperature, as well as ventilation and air permeability. The ambient temperature generally does not exceed 40°C, to maintain a good working environment for the vibrating screen.

In the sieving of titanium dioxide, the common titanium dioxide is 40-325 mesh or even finer. Because the choice of titanium dioxide vibrating screen should contain many elements such as: particle size structure, specific gravity, water content, viscosity, temperature, disposal capacity, etc. Titanium dioxide vibrating screen can choose the following models:

1. Rotary vibrating screen (small output and general precision)
2. Linear screen (large output accuracy is not as good as rotary vibrating screen)
3. Ultrasonic vibrating screen (general output, high precision, mostly used for 200-500 mesh screening)

1. It is often necessary to reduce the load of the light vibrating screen and clean the vibrating screen
2. Change the inclination of the screen box
3. Adjust the feeding amount of the vibrating screen
4. Tighten the screen and draw the drive belt closer.
5. When nailing the screen frame of the vibrating screen, the bead shall be extended forward by 2 cm, and the suspended nail of the screen shall be nailed under the extended bead to prevent mixing of materials.

1. The sieve of the screen is blocked (anti-clogging device should be added)
2. The moisture of the material thrown into the vibrating screen is too large (the viscosity is large, and it should be put into the vibrating screen after proper drying)
3. Uneven feeding on the vibrating screen surface (add material divider)
4. The material layer on the vibrating screen is too thick (add material diverter to control the feeding amount)
5. The screen frame is not stretched forward.
