Sugar and other materials often need grading by size or cleaning of oversize lumps. A vibro screen shakes the material over a sieve to do that.
The shaking spreads the material over the mesh so the fine passes through and the oversize is carried off, separating it by size.
This guide explains what a vibro screen does, where it fits, and how to keep it reliable.
What a Vibro Screen Does
The material is fed onto a sieving mesh that is shaken, or vibrated, so the material spreads and moves over it.
The fine material falls through the mesh while the oversize is carried across and off the end.
So the material is separated by size, which grades it and takes out the oversize.
Where It Fits in the Plant
Grading sugar by size and taking out lumps suit a vibro screen in the sugar handling.
Other materials that must be sieved or cleaned of oversize also pass over a vibro screen.
By separating the material by size, the screen keeps the product graded and clean.
Signs the Screen Needs Attention
A vibro screen in trouble shows up in the grading.
- Oversize passing through the mesh
- The mesh blinding or blocking
- The shake turning weak or uneven
- Material not moving across the screen
- A torn or worn mesh
What Makes a Good Vibro Screen?
A vibro screen is judged by clean grading and a steady shake.
Clean Separation by Size
The screen must separate the material cleanly by size. Clean separation is the reason for the screen.
A Steady, Even Shake
The screen must shake steadily and evenly to move the material. A steady shake keeps the grading working.
Keeping the Screen Running
Routine attention keeps a vibro screen grading your material.
- Watch that the grading stays clean
- Clear a blinded or blocked mesh
- Watch that the shake stays steady and even
- Replace a torn or worn mesh
Common Questions About Vibro Screen
It shakes material over a sieving mesh so the fine passes through and the oversize is carried off, separating the material by size to grade and clean it.
On grading sugar by size and taking out lumps in the sugar handling, and on other materials that must be sieved or cleaned of oversize.
Fine sticky material can clog the openings of the mesh, which stops it separating. Clearing the mesh keeps the grading clean.
Watching that the grading stays clean, clearing a blinded mesh, watching that the shake stays steady, and replacing a worn mesh keep it grading.
Grade and Clean by Size
A vibro screen shakes material over a sieve to separate it by size, grading and cleaning it as it passes. Clean separation and a steady shake are what make it work.
