Linear vibrating screen

Product Introduction: The linear vibrating screen can be used for dry and wet screening, dehydration, media removal, and sludge removal of medium and fine-grained materials in industries such as coal selection, mineral processing, building materials, hydropower, and chemical engineering. The screening machine has advanced technical parameters, high vibration intensity, large processing capacity, and high screening efficiency. It adopts dual motor self synchronization to directly drive the vibrator through the coupling, with simple structure, easy maintenance, smooth operation, low noise, and long service life.

Linear vibrating screen structure

The linear vibrating screen is mainly composed of a screen box, screen frame, screen mesh, vibration motor, motor pedestal, damping spring, bracket, etc.

1. Screening box: It is welded from several steel plates of different thicknesses, with certain strength and rigidity, and is the main component of the screening machine.

2. Screen frame: made of pine wood or wood with small deformation, mainly used to keep the screen flat and achieve normal screening.

3. Screen mesh: There are several types of screens including low-carbon steel, brass, bronze, stainless steel wire, etc.

4. Vibration motor: (For detailed usage and maintenance methods, please refer to the vibration motor user manual).

5. Motor pedestal: When installing the vibration motor, the connecting screws must be tightened before use, especially three days before the new screening machine is put into use, and must be repeatedly tightened to avoid loosening and causing accidents.

6. Vibration damping spring: prevents vibration from being transmitted to the ground while supporting the entire weight of the screen box. During installation, the spring must be perpendicular to the ground.

7. Bracket: Composed of four pillars and two channel steels, it supports the sieve box. During installation, the pillars must be perpendicular to the ground, and the channel steels under the two pillars should be parallel to each other.

Working principle of linear vibrating screen

The linear vibrating screen is driven by dual vibration motors. When the two vibration motors rotate synchronously and repeatedly, the excitation force generated by their eccentric blocks cancels each other out in the direction parallel to the motor axis, and forms a resultant force in the direction perpendicular to the motor axis. Therefore, the motion trajectory of the screen machine is a straight line. The two motor shafts have an inclination angle relative to the screen surface. Under the combined effect of the excitation force and the self gravity of the material, the material is thrown forward in a jumping manner on the screen surface, thus achieving the purpose of screening and grading the material.

Advantages of Linear Vibration Screen

1. High screening efficiency. Due to the strong vibration of the screening box, the phenomenon of material blocking the sieve holes is reduced, resulting in a high screening efficiency and productivity of the sieve. The highest screening mesh is 400 mesh, which can screen out 7 different particle sizes of materials.

2. Low energy consumption. The structure is simple, the screen surface is easy to replace, and the electricity consumption per ton of material for screening is low.

3. Environmental protection and energy conservation. The equipment has a fully enclosed structure, no dust spillage, automatic discharge, high screening efficiency, and good energy-saving effect.
