Linear vibrating screen

The linear vibrating screen is mainly composed of a screen box, screen frame, screen mesh, vibration motor, motor pedestal, damping spring, bracket, etc. The linear vibrating screen uses a vibration motor to excite as a vibration source, causing the material to be thrown up on the screen while moving forward in a straight line. The material is evenly fed from the feeder into the feed inlet of the screening machine, and through multiple layers of screens, several specifications of sieved material and undersized material are produced and discharged from their respective outlets. It has the characteristics of low energy consumption, high output, simple structure, easy maintenance, fully enclosed structure, no dust overflow, automatic discharge, and is more suitable for assembly line operations

working principle

1. Vibration motor drive: The operation of the linear sieve is driven by a vibration motor. The vibration motor generates excitation force through the exciter, and moves the sieve box in a straight line.
2. Material input: The materials to be screened are fed into the screening box through the feeding port.
3. Screening process: The materials inside the screening box are subjected to centrifugal and inertial forces under the action of vibration, and move in a straight line on the screening screen. Smaller particles will pass through the pores of the sieve, while larger particles will be blocked on the surface of the sieve.
4. Material separation: During the screening process, materials that meet the requirements will fall into the aggregate box or conveyor belt below through the sieve, while materials that do not meet the requirements will be retained on the sieve.
5. Adjust vibration parameters: By adjusting the amplitude and frequency of the vibration motor, the screening speed and screening effect of the material can be controlled to meet the screening requirements of different materials.

product structure

• The linear screen is mainly composed of a screen box, screen frame, screen mesh, vibration motor, motor pedestal, vibration reducing spring, bracket, etc.
  Screening box: made of welded steel plates of different thicknesses, with certain strength and rigidity, it is the main component of the screening machine;
  Screen frame: available in stainless steel, carbon steel, or wood materials, mainly used to maintain the flatness of the screen mesh and achieve normal screening;
  Screen mesh: There are several types of screens including low-carbon steel, brass, bronze, stainless steel wire, etc;
  Motor pedestal: When installing the vibration motor, the connecting screws must be tightened before use, especially three days before the trial use of the new screening machine, which must be repeatedly tightened to avoid loosening and causing accidents;
  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;
  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.
