Large capacity coal vibrating screen

Working principle
DZSF series linear vibrating screen is a vibration motor drive,When two vibrating motors do synchronous reverse rotation,vibration force produced by the eccentric block in parallel to the direction of the motor axis offset each other,in the fold is perpendicular to the direction of the motor shaft for a resultant force,so the trajectories of sieve machine for a straight line. 

Two motor shaft relative screen surface a dip in the vertical direction,the vibration force and material from the force of gravity,the material being thrown up on the screen,jumping forward or a straight line so as to achieve the purpose of the screening and grading the supplies. Suitable for particle size in 0.074 5 mm,water content is less than 7%,non-viscous all kinds of dry powder or granular materials of screening The largest feed particle size is not more than 10 mm. 

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, the 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, the 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.
