Application:
The linear vibrating screen uses the principle of vibration motor excitation, so that the material is thrown up by the screen on the screen surface, and at the same time, it moves forward in a straight line to achieve the purpose of screening with a reasonably matched screen. The linear vibrating screen is suitable for screening any material of 0.074-6mm, and the maximum feeding size is not more than 10mm. Linear vibrating screens are widely used in the screening of materials in abrasives, chemical, pharmaceutical, metallurgy, building materials, food, carbon, fertilizer and other industries.

Description:
The linear vibrating screen is powered by a vibration motor, which generates linear excitation force through the rotation of an eccentric block, driving the screen body to perform periodic linear reciprocating motion. After the material is evenly distributed by the feeding device, layering and sieving are achieved during the throwing motion: fine particles quickly sink and pass through the sieve holes, while coarse particles move along the sieve surface to the discharge end. The equipment adopts a multi-layer screen structure, which can simultaneously separate various specifications of materials. Each particle size product is discharged from an independent discharge port. Its fully enclosed box design effectively prevents dust from overflowing, coupled with automatic discharge function, ensuring clean production. This device has the advantages of low energy consumption, large processing capacity, compact structure, and convenient maintenance, especially suitable for material grading operations in continuous production lines.

Working principle:
The linear vibrating screen is driven by double vibration exciters. When the two vibration exciters are synchronized and rotated in opposite directions, the excitation force generated by the eccentric block cancels each other in the direction parallel to the motor axis, and in the direction perpendicular to the motor axis. Stacking is a resultant force, so the trajectory of the screen is a straight line. The two motor shafts have an inclination angle relative to the screen surface. Under the combined force of the exciting force and the material’s self-gravity, the materials are thrown up and jump forward on the screen surface for linear motion, so as to achieve the purpose of screening and grading materials. Can be used to realize automated operations in the assembly line. It has the characteristics of low energy consumption, high efficiency, simple structure, easy maintenance, and fully enclosed structure without dust spillage. The maximum sieving mesh is 400 meshes, which can screen out 7 kinds of materials with different sizes.

Structure Description
The screening machine is mainly composed of screen box, screen frame, screen, vibration motor, motor pedestal, damping springs, brackets and other components.
1. Screen box: the number of different thickness steel plates welded together, with a certain strength and stiffness, is a major component of the screening machine.
2, Screen frame: a small wood made ​​of pine or the amount of deformation is mainly used to keep the screen flat, reaching the normal screening.
3, Screen: low carbon steel, brass, bronze, stainless steel wire mesh and several kinds.
4, Vibration motor (use and maintenance methods are detailed in vibration motor manual).
5, the motor pedestal: Install vibration motor, connecting screws must be tightened before use, especially three days before the new trial screening machine, must repeatedly tightened to avoid loose causing the accident.
6, Damping spring: to prevent vibration transmitted to the ground, while supporting the full weight of the sieve box, during installation, the spring must be perpendicular to the ground.
7, Stents: the four pillars and two channel composition, supports screen box, when you install the pillars must be perpendicular to the ground, the two pillars of the following channels should be parallel to each other.
