  • Aluminum Alloy
  • Lightweight plastic reduces the overall weight of the Vibro Sifter.
  • Copper wire
  • Cast Iron

Are there Limitations of Vibro Sifters?


There are limitations of using a Vibro Sifter which include:

  • A Vibro Sifter is a complicated machine whose use requires a professional. This increases the overall running cost of the machine.
  • The installation process requires a large space. This can be a challenge, especially when you have limited space.
  • Susceptible to lumps in the feed due to the operating space of the machine around the feeding zone. Since the machine operates at a slower pace, the breaking down of particles may be affected. This in return has the effect of discarding large particles during the separation process which leads to wastage

How Can You Choose Suitable Mesh Screen for Vibro Sifter?

The following are the considerations that you need to check when selecting a suitable mesh screen for your Vibro Sifter:

  • Mesh screen material. The type of mesh screen materials available includes woven stainless, which is the common one, and steel wire mesh screen material. Woven stainless material is a durable option and has a wide range of applications compared to the other materials
  • Mesh size. This helps in defining the maximum operating efficiency that a particular mesh screen can offer.
  • Mesh tension. It determines the ability of the mesh screen to hold the particles during the sifting process.

How Can You Improve Vibro Sifter Performance?

You can improve the performance of a Vibro Sifter through any of the following actions:

  • Allowing continuous feeding of material through the screen. The interrupted flow of materials through the screen affects the operating capacity as well as the screen mesh.
  • Maximize the screen mesh area by spreading the materials over it. Maximization allows for the whole screen mesh area to function which reduces the operating time and cost.
  • Ensure the screen mesh tension is correct for efficient screening capacity. A lower screen mesh tension reduces the screening capacity of your Vibro Sifter since it holds particle causing a blockage.
  • Use a high-quality screen mesh to facilitate the apertures are accurate which ensures quality performance of your Vibro Sifter
  • Install a mechanical screen mesh de-blinding technique to reduce the blockage of your Vibro Sifter. Such techniques include discs, balls or ultrasonic technology.
