The Working Principle and Components of A Vibrating Screen Machine

A vibrating screen is a simple piece of equipment, but its construction and working principle can be quite challenging for most people. Before we review how a vibrating screen machine works, let's discuss some of the basic components of the equipment. WANTONG shares with you.

Basic components

The vibrating motor

It is this motor that causes the multi-plane vibration. Keep in mind that this movement increases the speed of the material through the various screens. For this reason, the machine is equipped with an out-of-balance counterweight assembly.

High quality springs

The sieve is suspended from springs. The primary uses of these springs include:

Allowing the entire upper portion of the machine to vibrate freely, helping to minimize power consumption and acting as a damper, and preventing any vibration from being transmitted to the floor.

Screen Structure

This is where the screens are installed. It is these screens that separate the material according to its size/shape. The screens maintain tension to make it easier for the material to move in the direction of vibration. This can be in either a horizontal or vertical direction. The screen construction uses FDA approved seals to prevent cross contamination of product in different screens.

Hopper cover

It confines the material and keeps the machine and its surroundings free from dust.

External structure

The structure is made of stainless steel. It limits the product to be processed to the required size and fineness. To facilitate movement, the structure is equipped with nylon casters.

Working principle

The whole process can be summarized as follows:

1,The material to be separated is fed through the hopper (small hole in the top of the vibrating separator).

2,Make sure that the lid, screen structure and bottom frame are securely fastened with clamping rings.

3,Power the machine from the power supply and turn it on. Due to the imbalance of the counterweight assembly, the vibratory motor will be energized, causing a vibratory movement.

4,The screen/sifter will start vibrating. The material fed into the hopper will then pass through the screen depending on the particle size.

5,The material moves in a controlled path and leaves the system through the discharge system.

6,The main applications for vibrating screen machines may vary depending on the design and construction of the equipment. 

Some of the major industries that rely on the use of these machines include: pharmaceuticals, laboratory research, cosmetics, chemical processing, food processing, agriculture, etc. Clearly, a vibrating screen is an efficient machine for sorting, separating or sieving materials to the desired particle size for direct use or further processing. 

These machines come in a variety of designs and shapes. However, you need to buy high quality, efficient and cGMP compliant equipment. Contact us for a high quality product.
