Detailed Description And Technical Parameters Of Linear Vibrating Screen
Linear vibrating screen (linear sieve) is a commonly used closed light vibration screening equipment, the use of vibration motor vibration as a vibration source, the material on the screen surface was jumping forward movement, the material from the feeder evenly Into the sieve inlet, through the multi-layer screen to produce several kinds of sieve on the screen, sieve objects, were discharged from their respective exports.
Linear vibrating screen for the size of 0.074-5mm, water content of less than 70%, non-sticky variety of dry powder material screening, the maximum feed size is generally not greater than 10mm. The series of vibrating screen can also be liquid filtration screening operations, and more for sewage treatment, can also be used for larger particles of coal powder material screening, in the larger material processing, the thickness of the screen to be thickened, Motor power to be increased, changing the punching sieve as a screen and so on. Can be single or multi-layer use, the screen frame is generally wooden structure, if the output requirements are higher when the screen frame can be made of steel structure, if the screening of corrosive materials, contact with the material part of the use of stainless steel. Widely used in plastics, abrasive, chemical, pharmaceutical, building materials, food, carbon, fertilizer and other industries.
Linear Vibrating Screen features:
1. Good sealing, very little dust. The same time as the above-
2. Low energy consumption, low noise, long screen life. The same time as the above-
3. High precision screening, large processing capacity, simple structure. The same time as the above-
4. Fully enclosed structure, automatic nesting, more suitable for assembly line operations. The same time as the above-
5. All parts of the sieve are made of welded steel plate and profile welded together (part of the assembly between the bolts) the overall stiffness is good, solid and reliable.
Linear Vibrating Screen work principle:
Linear vibrating screen work, the two motor synchronous reverse rotation of the exciter to produce reverse exciting force, forcing the sieve to drive the screen to do the vertical movement, so that the material on the exciting force and cyclically forward a range , To complete the material screening operations. Linear vibrating screen is driven by double vibration motor. When the two vibration motor to do synchronization, anti-pot rotation, the eccentric block generated by the exciting force in the direction parallel to the motor axis offset each other in the direction perpendicular to the motor shaft stacked together, so the sieve machine movement trajectory For a straight line. The two motor shafts have an inclination angle with respect to the sieve surface. Under the combined action of the exciting force and the material gravity, the material is jumped forward on the screen surface to move forward, so as to achieve the purpose of screening and grading the material.
The screen machine mainly by the screen box, screen frame, screen, vibration motor, motor pedestal, vibration spring, bracket and other components.
1, screen box: from several different thickness of the plate made of welding, with a certain strength and stiffness, is the main part of the screen machine.
2, sieve frame: the pine or deformation of the smaller amount of wood, mainly used to keep the screen formation, to normal screening.
3, the screen: a low carbon steel, brass, bronze, stainless steel wire and other sieve.
4, vibration motor (use and maintenance methods see vibration motor instructions).
5, the motor pedestal: the installation of vibration motor, the use of the front connection screws must be tightened, especially the new screen machine trial three days before, must be repeatedly tightened to avoid loosening accidents.
6, vibration spring: to prevent vibration to the ground, while supporting the full weight of the screen box, the installation, the spring must be vertical and ground.
7, bracket: composed of four pillars and two channel steel to support the screen box, the installation of the pillars must be vertical and ground, the two pillars below the tank should be parallel to each other.
