VIBROSCREEN® Typical Applications


Separating Solids from Solids

(sifting, de-dusting and classifying)

Separating Solids from Solids

Gravity-fed and in-line pneumatic models

Kason offers VIBROSCREEN® configurations for three types of solids-solids separation:

  1. Sifting (also called "scalping" or "bolting"): Separating a small percentage of oversize solids from a large percentage of on-size solids

  2. De-Dusting: Separating a small percentage of undersize solids from a large percentage of on-size solids

  3. Classifying: Separating solids into two or more particle size fractions

These screeners operate on a batch or continuous basis at rates from several pounds/kilograms to 70 tons per hour, separating thousands of powder and bulk solid materials.


Separating Solids from Liquids

(dewatering, clarifying and liquid scalping)

Separating Solids from Liquids

Gravity-fed models only

VIBROSCREEN separators are engineered for three types of solids-liquids separation:

  1. Dewatering: Separating a small to medium percentage of liquid from a large percentage of solids

  2. Clarifying: Separating a small percentage of solids from a large percentage of liquids

  3. Liquid scalping: Separating a small percentage of oversize solids from a large percentage of on-size solids in a slurry

These screeners operate on a batch or continuous basis at rates from one to 2000 gallons (7571 liters) per minute, separating solids from thousands of liquids.
