Vibro sifter / vibratory sieve

Vibratory sieves are widely used in the processing industries as an efficient way of protecting ingredients and end-products from contamination and lumps. Industrial vibratory screeners are generally made of a single deck containing a mesh which is used for screening out oversize, agglomerates and foreign bodies from liquids and powder. The motor attached to the screen uses an out of balance force to create vibration, which sends the materials through the mesh.

While the word sieves and screens can be used interchangeably, sieves and strainers are not the same thing. Generally sieves can be used to screen powders and liquids, while the term strainer (also referred to as filtration) is more commonly used when referring to screening liquids or slurries.

The difference between circular and linear vibratory sieves are the way in which the machines are shaped and the motion they use to move materials through the mesh. In linear machines, the back and forth motion allows for powders to move linearly during the sieving process and are not typically used for liquid applications. Round vibrating screeners use a circular vibratory motion and are suited to both liquid and powder applications. While both linear and circular sieves use vibration to process materials, circular screening machines tend to be smaller in size and more hygienic in design, making them easier to fit into processing lines, improving process efficiencies, allow more sanitary screening and reducing labor costs.
