On industrial production floors, screening systems are used to facilitate the separation of materials based on their particle size. Commonly referred to as check screeners or separators, these systems safeguard quality by ensuring the removal of oversized contaminants. Screening systems can be broken into groups based on how they separate materials:
Sifters
Sieves
Sifting, or check-screening, is the process of running a product through a screen before you use the product to make sure there’s no outside contaminants. A centrifugal sifter is one type of sifting machine you might find on the production floor. A centrifugal sifter is used to sift and screen high volumes of material, at high speed and with greater efficiency.
A sieve, or separator, separates or breaks down a material by particle size. Sieves are commonly used to characterize and classify sand, aggregate, soils, coal, grains, and many types of fine powders. Sieve machines can be static or vibratory – using vibrations to separate the material.
In most industries, success depends on adhering to strict production requirements. Screening systems ensure extreme accuracy in distribution, compliance with rules and regulations, and batch-to-batch quality control. Advantages include:
