What is Dry Sift?
Definition of dry screen and water screen
What is Dry Sift? Dry Sift and water Sift refer to two different screening methods for the screening of granular materials. Among them, the Dry Sift is screened in the absence of water, while the water screen is screened in water.
The working principle of dry screen and water screen
- Dry Sift
The working principle of the dry screen is to collide and separate the granular materials on the screen through mechanical vibration, and form multiple layers of screening slag layers of different particle sizes on the screen, so as to achieve the purpose of screening. - Water sieve
The working principle of the water screen is to suspend the granular material in water through hydraulic action, and screen the material using the force of the liquid. Water screens are often used to screen materials with more dust or finer particles.
Third, Dry Sift and water screen use scenarios
- Dry Sift
Dry screen is often used to screen powder, particles, pieces and a small amount of water under the condition of the material, such as glass beads, magnetic materials. - Water sieve
Water screen is often used to deal with more dust, fine particles or high moisture content of materials, such as sand, stone, cement and so on.
Dry Sift and water screen precautions
- Dry Sift
When doing dry screening, we should pay attention to keep the screen surface clean and dry, to avoid the impact on the screening effect. At the same time, appropriate screening parameters should be selected, such as screening time and screening thickness. - Water sieve
In water sifting process, we should pay attention to controlling the flow rate and water level of water to avoid waste and loss of materials. At the same time, appropriate screening parameters should be selected, such as water temperature and flow rate.
Dry Sift and water screen FAQ
- Is the screening effect of dry screen and water screen different?
A: The screening effect depends on the nature of the material and the selection of screening parameters, dry screening and water screening in different scenarios can achieve good screening effect. - Is the mesh size of dry screen the same as that of water screen?
A. It’s different. Because the dry screen and water screen work in different ways, the screening mesh size is also different. Usually, a water screen will select a finer mesh than a dry screen to achieve better results.
【 Conclusion 】
Dry screen and water screen are two common screening methods for granular materials, and their working principles and use scenarios are different. When selecting the screening method, the appropriate way should be selected according to the characteristics and needs of the material, and pay attention to the selection of screening parameters and the implementation of precautions to achieve the expected screening effect.
