Separation

Pretension Screens

Details

Our round mesh separator screens, also known as vibrating screens or shaker screens, are used extensively in the chemical, food & beverage, and cosmetics industries.

These circular screens are available in a number of shapes and sizes, and are sometimes referred to as ‘pre-tension’ screens as the mesh is put under tension before it is sealed at the rim.

Our round mesh separator screens feature rolled foundation rings fabricated from high-quality 304 stainless steel. They are seam welded to create a clean contact surface that prevents material from getting trapped. A wide variety of sizes are available: 18″, 24″, 30″, 36″, 40″, 48″, 60″ and 72″.

These round mesh screens are fabricated from FDA-approved components. Please specify all special fabrication options required.

Select from a wide range of mesh sizes from one-inch to 500 mesh, select alloy type required T304 / T316 / T430. Specify optional backup mesh layering when needed.

Our skilled fabricators and manufacturing methods ensure uniform screen tension. Proper tension extends screen life by reducing the amount of flex in the mesh and improves overall screen performance. Flexure of the mesh over time leads to fatigue failure.

We offer two methods for securing screen edges:

  • Epoxy – Epoxy mounted pretension screens allow for functional maintained tension, smooth surface for food grade/pharma applications, the secondary application provides for 100% encapsulation of edge wires
  • Welded – Welding is an ideal solution when 1) any part of a process could cause an adverse chemical reaction with the epoxy, or 2) high-temperature applications preclude the use of epoxy

Self-Cleaning Screens

A sandwich screen keeps sliders, or sliders and deblinding balls, between the sizing mesh and a coarser carrying mesh. The sizing mesh is mounted on one side of the frame or ring, and the coarser mesh is mounted on the opposite side.
