Application Of Vibrating Screen In Glass Powder Production Process
Glass powder rotary vibrating screen recommended rotary vibrating screen model and amplitude adjustment
Dayong Vibration Equipment Company recommends choosing DY-800 or DY-1000 stainless steel vibrating screen, and the specific number of layers can be determined according to the level of screening required. The recommended amplitude is 8-10 for the former and 10-12 for the latter. (specifically adjusted according to requirements).
About the amplitude and exciting force: You can adjust the phase angle of the weight block or increase or decrease the weight block to make the rotary vibrating screen generate different exciting force and amplitude, so as to change the movement trajectory of the material, so that the material can be obtained on the screen surface. Sufficient vibrating screening to meet the screening requirements of different materials and achieve the highest screening accuracy and output. The adjustment of the amplitude can be divided into two aspects: horizontal and vertical. The amplitude of the amplitude directly affects the screening output. The increase of the horizontal amplitude makes the material on the screen move faster to the edge, and the increase of the vertical amplitude makes the material on the screen stronger. Adjust the amplitude of the amplitude by adjusting the relative weights of the upper and lower weights. The amplitude of the amplitude should not exceed a certain range, otherwise the service life of the vibrating screen will be affected.
Glass powder is a kind of easy-grinding, scratch-resistant and highly transparent powder with small particle size, good dispersibility, high transparency and good anti-settling effect; after several surface improvements, it has good affinity and strong position It can be easily dispersed in the paint, and can increase the fullness of the paint after film formation. The crystal clear primers made can not only maintain the transparency of the varnish, but also provide good sandability. It is mainly used as a crystal primer in the production of high-end furniture. It is also widely used as a dual-purpose paint for decoration.
Physical indicators:
Appearance: white powder;
Whiteness: ≥93
PH value: 6-7
Average particle size: 2.5±0.5um
Specific gravity: 2.7g/ml
Oil absorption: 28±2.5g/100g
Mohs hardness: 7.8
Chemical composition: Silicate
Features of glass powder:
1. Glass powder has good transparency, high hardness and uniform particle size distribution.
2. The glass powder has good dispersibility and good compatibility with other components in the resin and paint system.
3. The glass powder has been surface-treated for many times and filled in the paint system. The paint film has no blue light and has good repaintability.
4. When used in high-grade scratch-resistant topcoat, it can increase the hardness and toughness of the topcoat, improve the scratch resistance of the paint film, and has a matting effect, which can improve the weather resistance of the paint film.
5. Compared with talc powder and glass powder, it is easier to precipitate after the paint is diluted, so the anti-settling measures should be properly strengthened.
2. Application of glass powder vibrating screen:
1. Glass powder vibrating screen
The advantage of the glass powder rotary vibrating screen is that the screening accuracy is higher, and the disadvantage is that the output is lower than that of the glass powder linear vibrating screen.

② the operation mode of glass powder on the vibrating screen
Adjusting the phase angle of the upper and lower ends of the vibration motor can change the movement trajectory of the glass powder on the screen surface, and the glass powder should move in a vortex on the screen surface.
③the advantages of glass powder vibrating screen
a. Compared with the glass powder linear vibrating screen, the rotary vibrating screen has the advantage of high screening accuracy in the screening of glass powder and glass particles
b. The vibrating screen has beautiful appearance, small footprint, light and convenient, easy to move back and forth
c. The screening process is completely closed, the powder does not fly or leak, and the production environment is improved;
d. It can be screened in multiple layers, and the height can reach 5 layers.
e. The discharge direction can be adjusted arbitrarily, and all the screening materials are automatically discharged, which is more suitable for screening a large number of materials, and is easy to configure in the production line.
f. The gate design can be installed according to customer requirements, and the screening accuracy can be further improved as required
