As we all know, vibrating screen is a suitable for wet fine grade difficult screening material dry screening mechanical equipment, is also a common choice to deal with difficult screening materials in China.
The traditional vibrating screen is not necessarily the best choice for all materials, lime powder is one of the best examples, its best partner is not rotary vibrating screen, but swinging screen.
The radial inclination Angle and tangential inclination Angle of the swinging screen lead to the material on the screen surface of the gradually open spiral motion, this motion trajectory makes the material can be in a relatively small area, take a relatively long way, in order to improve the screening accuracy.
Lime Powder Vibrating Sifter is a relatively new product in the industry, its price is much higher than vibrating sieve (rotary vibrating sieve, linear sieve), so why is it still being followed by lime powder merchants? Investigate the reason, on the one hand, swing screen processing is more complex, many processes; On the other hand, swing screen is a new product, involved in relatively few manufacturers.
So what are the advantages of Lime Powder Vibrating Sifter over vibrating sifter?
After comparison, it is found that: for coarse materials above 30 mesh, the output of vibrating screen and swinging screen is basically the same, but the maintenance cost of swinging screen is relatively low; for materials of 30-500 mesh, the output of swinging screen is much higher than that of vibrating screen, swinging screen The sieve is 5-10 times that of the vibrating sieve; in addition, for hard materials with severe screen wear, the service life of the oscillating sieve can be doubled.
2. Screening area
Take the more mature circular vibrating screen in the market as an example, its screening area is generally below 1500mm, and the maintenance rate of models above 1500mm is very high. This is mainly because the vibrating motor used in the 1500mm circular vibrating screen has a large power, which will damage the body while screening materials, and the larger the frame, the more serious the damage. If it is multi-layer screening, the effect will be better. Difference.
The swinging screen uses an ordinary motor. After the speed is changed, the entire frame body performs a low-speed rocking motion, and the body does not vibrate, so the frame body is basically not damaged. At present, the model range of the swinging screen has reached 600mm-2600mm. From this point of view, the model and output range of the vibrating screen are relatively large, which can fully meet the requirements of customers with large output and high precision beyond prehistoric times.
3. Maintenance rate and service life
The vibrating screen uses the principle of high-speed vibration. The vibration is very destructive to the machine itself, and it is prone to vibration cracking or deformation after a long time. Therefore, the breakage of the screen is often not caused by normal wear, but by its own friction. In addition, the noise of the vibrating screen is relatively large, the service life of the vibrating motor is short, and the maintenance rate is high.
The swinging screen adopts the low-speed swinging principle, which ensures the service life of the equipment, reduces the maintenance cost, reduces the noise of the equipment, and makes the use of the equipment safer.
4. Impact on materials
As we all know, the vibrating screen uses the principle of high-speed vibration to sieve materials. It is precisely because of the high-speed vibration that the shape of the material will be destroyed, so many granular crystalline crispy materials are not suitable for vibrating sieve screening, such as chicken essence, monosodium glutamate, sugar, Deli and more. The oscillating screen is a slight elliptical rocking motion, without high-speed vibration, which has little impact on the material, does not damage the shape of the material, and greatly improves the yield of the material.
5. Price and affordability
On the surface, vibrating screens and their accessories are relatively cheap. This is because there are many manufacturers of rotary vibrating screens and the competition is fierce, so that the price of vibrating screens is infinitely close to the cost, and the price is very low. As a new product with relatively high technical content, the swing sieving machine is more complicated than the rotary vibrating screen, so the current price is still relatively high.
However, considering the output, maintenance rate, service life and other factors of the two products, in the long run, the swinging screen is more affordable and superior than the vibrating screen, and can achieve both output and precision.
