Screeners Explained: Enhancing Performance with Cutting-Edge Screener Technology

At Stewart Plant Sales, we pride ourselves on offering a comprehensive range of material processing equipment, including crushers, screeners, and stackers from renowned manufacturers such as Tesab and Lippmann. In this blog, we will delve into screeners, examining how they work, the benefits they provide, and an overview of the models we have available.


What is a Screener? 

Screeners are indispensable tools used across various industries, including mining, recycling, aggregates, and agriculture. They ensure efficient and accurate separation of materials such as soil, sand, or gravel. While screeners can operate as standalone units, they are often integrated into a processing train alongside crushers and stackers to maximise productivity and efficiency.

Accurate material separation post-crushing is as crucial as the crushing process itself. Our range of Tesab, Lippmann, and McCloskey Environmental screeners excels at extracting clean materials from secondary crushing processes, handling materials such as stone, concrete, and chips. 


How does a Screener work? 

There are four main stages to the screening process:  

  1. Feeding – Raw material is fed into the screener. 
  2. Vibration –When the machine is powered the screener vibrates which makes the material move across the screens.  
  3. Separation - As the material moves, smaller particles pass through the holes in the screen, while larger particles remain on top. 
  4. Collection - The separated materials are collected in different outputs for further processing or use. 


H2: What are the Main Parts of a Screener?  


  • Feed Hopper – The starting point where raw material is loaded. Available in various sizes depending on the model.


  • Vibrating Screen Decks – These decks separate material into desired sizes. Typically made from wire mesh, perforated metal, or punched plates, the screens are inserted in tiers within the screener chassis. When powered, the screens shake, allowing the chosen sizes of the product to fall through the gaps and be screened out.


  • Double Deck Screeners can sort two sizes of products and an oversize.


  • Triple Deck Screeners can produce three different sized products. Fine screening screens are usually inclined, enabling non-falling material to tumble onto a conveyor for further processing.


  • Discharge Chutes – Once sifted, the material exits the screener for use or additional sorting.
