Many industrial sieves are used for a variety of different applications, not simply for screening and separating. The most common industrial sieve is the check sieve. The check sieve is often used to remove bits of packaging and lumps from the product. Check sieves are usually a single screen and typically the fine product that passes through the mesh is kept.
Another common industrial sieve is the grading sieve, the grading sieve is similar to the check sieve but offers more precision of the sieving process. The aim of a grading sieve is to take exact cuts of different particle sizes.
Powder sifting
Powder sifting can be described as separating, sieving, de-lumping, and screening, but each description is a different method of sifting requiring a different type of sifting motion.
The centrifugal sifter is a popular powder sifter specifically designed for sifting high capacities of product and removing unwanted material from the material stream. In addition to the centrifugal sifter, the vibratory sifter is a sifter that shakes the body of the machine, transferring this vibration to a high tensioned screen cloth. It is designed to size or classify powder. The gyratory sifter uses a non-vibratory motion that is gentle on friable powders and therefore can utilize ball cleaning of the screens.
