One of the first options for screens is model type. This depends solely on the application so the application will determine what model of screen is needed. JVI can recommend the best type of screen options for your application.

TYPE OF DUTY

• Classifying
  If you need to separate material into two or more sizes you will need a classifying screen. Classifying screens come in many sizes from heavy duty mining screens to very small light duty batching screens for pharmaceutical and food ingredients. JVI will recommend the most effective size machine and screen mesh for the application. Screens can be designed with 2 or 3 screening decks for more complete screening, or for separating into more than two sizes.
  
      
  
• Grizzly Screening
  The appropriate size and shape of finger grid will make a grizzly screen more efficient. JVI will make recommendations based on the application.

• Dewatering
  This is separation of solids from liquids. Best results are achieved by upwardly inclining the screen to “cake” the material. Moist sand, for example, coming from a degrader, is dewatered so that it can be conveyed by belts, as shown below.
  
• Banana Screens
  These screens have a steeply angled deck at the start of the screening path and are ideal for increased capacity and large amounts of fines.

Type of Motion

Linear Motion Screen - JVI's linear screeners are designed for applications requiring maximum screening efficiencies. Mounted horizontally and driven by two counter rotating JVI electromechanical unbalanced motors, the resulting linear stroke facilitates particle stratification and optimum particle size separation. Motors can be mounted on the top, bottom or side of the screener. Linear motion screens require the least amount of headroom when installed with near horizontal decks. Typical applications for linear motion screens are classifying, dewatering, grizzly and control screen applications.

Circular Motion Screen - JVI's circular or elliptical screeners are used in scalping applications to remove tramp or oversized product from the process. This design has the screener mounted on a 15 degree decline and incorporates a single JVI electromechanical motor that produces the circular stroke.

Screen Deck Mesh Size and Material

Depending on the application requirements a type of screen deck and mesh size will need to be selected. JVI will recommend the most efficient arrangement for your application. Here are few examples of the many possibilities:

Plastic Flip Flop mesh is pliable and works excellent for recycling applications, the flapping effect of this screen prevents material from getting stuck.

Fine Wire mesh is the choice for classification of small particles such as sand and small gravel, minerals, or grains.

Coarse Wire mesh is used for separating any type of solid, large sized material.

Perforated Steel Plate mesh is an option
as well as Polyurethane mesh.

Drive Type and Position

Exciter - for heavy duty applications such as mining are usually installed across the top of the machine.

Electromechanical - for light to medium duty screening or circular motion screens can be arranged with one or two drives above or below the machine.
