Vibrating Screen Machine

Vibrating Screen Machine

The vibrating screen, or shaker screen, is another type of screening device used to separate and segregate materials and stones from each other. This device is considered more compact and widely used compared to other types of screens.

The vibrating screen machine usually consists of a series of steel frames positioned horizontally. These frames hold the screens of the machine and are also vibrated by unbalanced weights that produce off-center driving force. This vibration within the vibrating screen creates horizontal and vertical movement in the particles of stone and materials inside the screen.

Operation of the Vibrating Screen Machine

To optimize the entire usable screen area, vibrating screen machines are generally made in various dimensions and sizes. This allows these machines to screen and classify materials at different capacities calculated in tons per hour. The screens of vibrating machines, particularly vibrating screens, come in various types. For instance, there are iron screens or steel screens. Additionally, thick screens are another type produced in various dimensions.

The most common application of vibrating screens is in ore dressing plants and workshops. In some crushing methods, the vibrating screen is replaced by a grizzly screen. In a vibrating screen machine, the main body is essentially an assembly of high-strength steels welded together.

These steel bodies provide a suitable and strong platform for the screens to be placed upon. The body of this type of screen is installed on a chassis, also made of steel, with double bases. Additionally, the places where the final materials and compositions exit, known as the outlet chutes, are also attached to this chassis.

Features of the Vibrating Screen Machine

The vibrating screen machine has many advantages and features. One of these advantages is the low maintenance and repair costs. Vibrating screens require daily greasing to prevent failure. The screens in these machines are replaceable, meaning if a change in the output size is needed, the screens can be replaced in the vibrating screen to achieve the desired output size.

These screens must be made from the best alloy materials to be durable and strong, thereby increasing the quality of the output materials and products. It is noteworthy that if the vibrating screen is mounted on a movable chassis, it can be relocated and easily used in various locations. Vibrating screens require daily greasing to prevent failure.

The vibrating screen machine is characterized by its structural strength and high resistance. The body of this device is made using seamless welded plates, which enhances its strength. Additionally, its shafts are made from alloy steel, which increases their resistance and extends their useful life.

To enhance resistance, the vibrating screen is equipped with a dual-bearing system and, in some models, made with beams for the construction of stages. The slope design in this device is made according to standards to ensure a more orderly classification, and the lubrication system is either oil-based or grease-based.

Specifications of the Vibrating Screen Machine

Vibrating screens primarily move vertically. The needed vibration is generated mechanically or electromagnetically. Initially, the screen is elliptical, tilted forward, leading to rapid transfer of remaining material over the screen, including coarse particles, towards other parts of the screen.

In the central part of the screen, the surface motion is circular, which reduces the velocity of particle movement across the screen. Thus, fine grains remaining on the screen have the opportunity to pass through screen meshes.

At the end of the screen, motion becomes elliptical with backward inclination again. This movement acts as a restraining force against the forward movement of surface particles, allowing particles close to the mesh size more passage time.

In a vibrating screen device, a pair of off-center mass weights is typically mounted on the shaft, causing it to rotate. The vibration mechanism for the horizontal screen results in backward and forward movement, while the vibration surface has a circular inclination. Various methods exist to generate this vibration. In the horizontal screen, a double balancing system is used, and the vibratory screen’s motion amplitude can be adjusted by the amount of mass.

With vibrating screen vibrations, rocks rise above the screen surface. These vibrations cause stones to pass over the screen mesh. If the stones are small enough, they exit the screen circuit quickly; otherwise, larger stones move to the next stage.

This process allows ores within a size range of 250 microns to 250 millimeters to select the most suitable particles for screen mesh passage. Generally, vibrating screens are predominantly used in ore refining plants for sorting materials within the size range of 5 to 250 millimeters.
