Vibrating Screens and Uses

A vibrating screen is a large mechanical tool which is used to separate solids, liquids and powders. The machines use gravity, motion and mesh screens to screen many different types of material. These screens cut out a lot of time and the work of several people, making the manufacturing process of materials far more efficient and cost saving.

Vibrating Screens are used in many manufacturing process where there is a need to grade and size material. Also vibrating screens are widely used to crush, grind, separate and classify various kind of industrial raw material including foods. In the production of biscuits, sieves and screens are used in the milling of the flour to screen against any foreign bodies or contaminants found in these raw materials.

A vibrating screen separator is made from solid metal such as steel. It has two opening sides so workers can visually monitor the progress of the screen. Most vibrating screens have four or more levels of wire mesh screens which are stacked on top of one another. The come in a variety of sizes or made bespoke to fit an individual process.

The food industry uses screens for many applications including the screening and separating of flour, corn, milk powder, cocoa, pepper, pet food, cereals, peanuts and sweets. In the food industry is it very important to screen foods. The ability to identify toxic heavy metals such as cadmium, lead, and mercury in food and water is essential to food safety and consumer health.

Other uses can be found the chemical and pharmaceutical industries. Capsules, tablets, powders all need to be screened in their production which is where vibratory screens come in. With powers and granules, these fine particles all need to be finely screened; even applications of up to 750 microns in diameter can be screened.

The agricultural industries use screens them to separate materials like sugar beet, oats, corn and animal feed. Fertilizers used by the agricultural industries play a vital role in sustaining crop. Producing and monitoring the purity of fertilizers is a difficult application due to the high concentration of the active ingredients, and the low concentration of contaminants.

Vibratory screens today use up to date technology which gives products the dental touch on the product but an effective screening also. Most screens are bespoke and are built exactly to the applications requirements. Ultrasonic technology is used which allows efficient screening and classification of materials and products, meaning the finest powders of up to 50mm in diameter can be used.
