Vibratory Screeners and How They Work


We use the production line in the manufacturing and processing of many things. One of the most important methods of processing on a production line involves using vibratory screeners to separate items according to size. Vibratory screeners are able to work with materials that are both wet and dry.

How Do Vibratory Screeners Work?

The screen vibrates at a certain frequency. This frequency is controlled by a vibrator connected to the surface of the screen, which operates magnetically. There are two categories of screening: wet and dry. The vibration of the screen takes a steady flow of material and divides it into grades, with certain size pieces falling through and other parts continuing on. The materials that pass over and through the vibrating screeners will then go on to be processed further.

Is There Just One Type of Vibratory Screeners?

There are several types of vibratory screeners, widely divided into high-frequency vibratory screeners and other types of vibratory screeners, which are then named for their machine motion. The high-frequency version has a fixed frame and the vibrator only activates the screen cloth. The high-frequency version is for dealing with particle sizes from 3mm down to +150 mesh. Other types of vibratory screeners include trommel screens and circle-throw vibrating equipment.

What are These Machines Used For?

This sort of machine is frequently used to separate metal ores, rock of all kinds, and anything else that needs to be sorted and screened for size. Vibratory screeners are widely used in the mining and mineral processing industries, as well as in agricultural, food, plastics, and even pharmaceutical applications.

What Other Machines are Involved in This Kind of Work?

There are other types of machines that are typically used in the same types of processing as vibrating screeners. The tumbling drum is one of them. Tumbling drums are able to remove unwanted parts, finish and polish surfaces, and separate materials. Tumbling can take from six to 24 hours, depending upon the materials in use. A tumbler is usually 18″ to 36″ in diameter and between 18″ and 42″ in length, with the diameter traditionally smaller than the length. Most barrels are designed to be loaded no more than 45% to 60% of capacity, with smaller loads producing more action but poorer finish.

Crumblers, tumblers, vibratory screeners, surge machines and crushers: these are just some of the machines that are used to process metal ores, rocks, plastics, and a host of other materials. They are essential bits of custom machinery used every day in the manufacturing and processing of many industries. Having good quality machines is an important first step in ensuring a good quality final product.
