Linear vibrating screen is a new type of vibrating screen machine, widely used in mining, coal, smelting, building materials, refractory materials, light industry, chemical industry, and other industries. The linear vibrating screen can also screen and classify powdery and granular materials, and is widely used in plastics, abrasives, medicine, grain carbon, fertilizer and other industries.

The linear vibrating screen uses the principle of self-synchronized vibration, using a vibration motor as the vibration source, a rubber spring as a shock absorber and a highly wear-resistant material as a sieve plate, and eccentric compression sealing and other advanced technologies. It has advantages of long life, low noise, and high screening efficiency. Apply for sieving ore, natural ore, coke and other powdery materials.

Linear vibrating screen parts

The linear vibrating screen is mainly composed of screen box, screen frame, screen mesh, vibration motor, motor base, vibration damping spring, bracket and so on.

Screen box: It is welded by several steel plates with different thicknesses and has certain strength and rigidity. It is the main component of the screen machine.

Screen frame: It is made of pine wood or wood with a small amount of deformation. It is mainly used to keep the screen mesh flat and achieve normal screening.

Screens: There are several kinds of screens such as low carbon steel, brass, bronze, stainless steel wire, and so on.

Vibration motor: more details at the operation manual of the vibration motor.

Motor pedestal: Install the vibration motor, the connecting screws must be tightened before use, especially three days before the new sieve machine is tried out. It must be tightened repeatedly to avoid accidents caused by loosening.

Vibration damping spring: prevent vibration from being transmitted to the ground and support the full weight of the screen box. During installation, the spring must be perpendicular to the ground.

Bracket: It consists of four pillars and two-channel steels, supporting the screen box. The pillars must be perpendicular to the ground during installation, and the channel steels under the two pillars should be parallel to each other.

Advantages of circular vibrating screen

  • Unique screen structure design: easy and quick to replace screen;
  • Easy to operate: the vibrating screen design is delicate and easy to assemble, one person can operate the sieve machine;
  • Large capacity: compared with other related vibrating screen manufacturers, our vibrating screen has a larger screening area and a high-yield processing capacity;
  • Long use life: The mother net fully supports the fine net, so the fine net can have a longer life, and reduce the consumption of the fine net, then the long-term production process can reduce many costs.
  • High screening efficiency: stable and reliable operation, low consumption.
  • Low noise: the linear vibrating screen adopts advanced anti-noise equipment. The lower noise is produced during operation.
  • Stable vibration: the linear vibrating screen adopts advanced technology at home and abroad, plus decades of manufacturing technology. In the production, the vibration is very stable and there is no bad operation.

Linear vibrating screen working principle

The linear vibrating screen uses vibration motor excitation as the vibration source, so that the material is thrown on the screen and moves forward linearly. The material enters the feed port of the screening machine evenly from the feeder, and several The oversize and undersize products of specifications produced through the multi-layer screen are discharged from their respective outlets. It is more suitable for assembly line operations.

The linear vibrating screen uses the counter weights installed at the upper and lower ends of the motor shaft to convert the rotary motion into horizontal, vertical, and inclined three-dimensional motion, and then transmits this motion to the screen surface. The change of the phase angle of the upper and lower counter weights can change the direction of material travel.

The linear vibrating screen is driven by dual vibration motors. When the two vibration motors are synchronized and counter-rotated, the excitation force generated by the eccentric block cancels each other in the direction parallel to the motor axis, and stacks in the direction perpendicular to the motor axis. As a result, the trajectory of the screen machine is a straight line. The two motor shafts have an inclination angle with respect to the screen surface. Under the combined action of the exciting force and the gravity of the material, the material is thrown up and jumped forward in a linear motion on the screen surface, so as to achieve the purpose of screening and grading the material. It can be used for automatic operation in the assembly line. It has the characteristics of low energy consumption, high efficiency, simple structure, easy maintenance, and no dust spillage in the fully enclosed structure. The sieve mesh number is up to 400 meshes, and 7 kinds of materials with different particle sizes can be sieved.
