What Are the Best De-Blinding Options for Sticky Materials?

For sticky or fatty materials, we recommend Nylon Sliders, which shear material from the bottom of the mesh to stop "blinding." For dry particles that get stuck in the holes ("pegging"), we recommend Rubber or Silicone Balls, which provide vertical impact to dislodge them.

The Physics of De-Blinding

A screen that is 10% blinded has lost 10% of its revenue potential. Choosing the right cleaner depends on the material:

1. Sliders (Nylon Discs)

Best For: Sticky powders, fatty foods, or materials with static charge.

How they work: They slide horizontally across the perforated plate beneath the screen. This shearing action "wipes" the underside of the mesh, cutting off hanging stalactites of product.

2. De-Blinding Balls

Best For: Granular, hard, or irregular shapes.

How they work: As the machine vibrates, the balls bounce randomly against the mesh. This vertical impact "kicks" near-size particles out of the holes.

Note: Always check chemical compatibility—use White Silicone balls for food applications and Black Rubber for aggregates.

3. Sandwich Screens

For ultra-fine mesh where a perforated plate restricts flow, we can build a "Sandwich Screen." This integrates the cleaning media (balls or sliders) directly between a coarse backing mesh and the fine top mesh, allowing for maximum airflow and cleaning action in a single unit.
