INTRODUCTION FYBS1 gyratory screen is a kind of efficient screening equipment, having high precision and large production. It is widely used in the industries including chemical, metallurgy, ferrous metal, non-ferrous metal, food and abrasive, etc. WORKING PRINCIPLES FYBS1 gyratory screen is also called reciprocating screen, if see from the motion trail of screen box. The vibratory force produced by its driving device is the inertial force twining along the dead axle, the direction of which is change according to a certain regular. The essence of square gyratory screen is the reciprocating intertia force formed by the rotation of eccentric wheel winding the dead axle. According to the structure characteristics and working principle of rocking screen, its screen surface is arranged with level or incline(the angle of inclination is 0-5 degree). working principle of gyratory screen is that after starting the screen machine, the shaking body of screen machine namely screen box make ront-rear reciprocating motion under the action of the inertial force, screen box drives screen surface to make periodic shaking, which makes the materials on the screen surface to make directional jumping movement with the screen box. During the period, the material less than the aperture of the screen surface fall to under layer through the sieve mesh to became the screen underflow. The material greater than the aperture of the screen surface is discharged from the discharge gate after the continuous roll jumping movement and finally complete screening work.
