Detailed introduction of linear vibrating screen
General introduction of linear vibrating screen
Linear vibrating screen (linear sieve) is a kind of commonly used enclosed light vibrating screen equipment, using the vibration motor excitation to cheer for the vibration source, make the material on the screen is jumping straight forward movement, the material from the feeder evenly into the sieving machine feeding port, several kinds of specifications by multilayer sieve sieve, sieve, respectively from the respective outlet.
Application range of linear vibrating sieve
Linear vibrating screen is suitable for the size in 0.074-5mm, water content less than 70%, no viscosity of all kinds of dry powder material screening, feed size is generally not more than 10mm.This series of vibrating screens can also be used for liquid filtration and screening, which is mainly used for sewage treatment, but also for the screening of coal powder materials with larger particles. In the treatment of larger materials, the thickness of the screen body shall be thickened, the motor power shall be increased, and the punch screen plate shall be replaced as the screen screen.Single-layer or multi-layer use, screen frame is generally a wooden structure, if the output requirements are higher when the screen frame can be made of steel structure, if the screening of corrosive materials, with the material contact part made of stainless steel.Widely used in plastics, abrasive, chemical, pharmaceutical, building materials, food, carbon, fertilizer and other industries.
Characteristics of linear vibrating sieve
1. Good sealing, little dust spill.
2. Low energy consumption, low noise, long screen life.
3. High screening accuracy, large processing capacity and simple structure.
4. Fully closed structure, automatic material arrangement, more suitable for assembly line work.
5. Each part of the sieve body is welded by tie steel plate and profile (bolted connection between some groups) with good overall stiffness and reliability.
Working principle of linear vibrating screen
When the linear vibrating screen is working, the two motors rotate synchronously and reversely to generate the vibration force of the shaker, which forces the sieve body to drive the sieve net to do longitudinal movement, so that the materials on it are periodically thrown forward to a range due to the excitation force, so as to complete the screening of materials.Linear vibrating screen is driven by double vibrating motor.When the two vibration motors are rotating synchronously and inversely, the excitation force generated by the eccentric block will cancel each other in the direction parallel to the motor axis, and stack as a resultant force in the direction perpendicular to the motor axis, so the motion track of the sieve machine is a straight line.There is an inclination Angle between the two motor shafts and the screen surface. Under the combined action of excitation force and material from gravity, the material is thrown up on the screen surface and makes a straight movement forward by jumping, so as to achieve the purpose of screening and grading the material.
