A Simple Guide to Vibro Sifter Selection

With the increasing popularity of vibrating screening equipment, how do you determine the most suitable sieving machine for your specific application? Below is a simple, short, descriptive guide that introduces the vibro sifter selection of the most popular dry bulk solids screening technology:

A. Material characteristics and requirements

1. The characteristics of the material to be processed

Such as material name, particle size structure (fine powder to coarse particles and lumps), water content, temperature, density, etc.)? Is the material sticky?

2. The purpose of use (removal of impurities, classification, filtration or other)?

3. What is the ratio of the on-sieve to the under-sieve?

4. What is the processing capacity per hour?

5. How many layers of screens are needed? What is the screen size of each layer?

6. The material requirements of the equipment (carbon steel, stainless steel, plastic, etc.)?

7. What is the voltage, power and frequency of the vibration motor?

According to the characteristics of different materials, we recommend the following sifters

1. Irregularly shaped materials are easy to block the screen during the screening process, and require high screening accuracy and high output. You can choose tumbler screen.

2. Granular materials with dry, high specific gravity and good fluidity are materials that are easy to sieving, you can choose to use vibro sifter.

3. Viscous materials, high static electricity materials, etc. are easy to cause the materials to stick together during the screening process, which will cause the screen to block and reduce the screening efficiency. Generally, it is recommended that you use an ultrasonic vibrating screen or a centrifugal sifter.

4. If your screening material cannot be in contact with oxygen, you must pay attention to the selection of the vibrating screen. Remember to choose a screening equipment with good air tightness. The gas protection vibro sifter is developed for this special screening environment. .

Typical Sifting Applications

Classification-divide the particles and powders into different particle segments, and can continuously sort out 2-6 particle sizes to control a narrower particle size range. Removal of impurities-high-precision screens can quickly remove large or small particles with a lower percentage in the processing of high-flow materials.

Solid-liquid separation-can quickly remove insoluble solids in various slurries.

De-dusting-remove fine powder from raw materials

De-agglomeration-screening and crushing of soft lumps to recycle usable feed products, otherwise they may be treated as waste

1. Irregularly shaped materials are easy to block the screen during the screening process, and require high screening accuracy and high output. Swing screens can be selected.

2. Dry, high-density, high-fluidity granular materials are materials that are easy to sieve, and you can choose to use ordinary rotary vibrating screens.

3. Viscous materials, high-static materials, etc. are likely to cause the materials to stick together during the screening process, which will cause the screen to block and reduce the screening efficiency. Generally, it is recommended that you use an ultrasonic vibrating screen.
