» Working Principle FYBS1 Swing(Gyratory) Screen To pursue screening precision will sacrifice the output, pursuing big output will drop the precision. Weiliang FYBS square swing screen is special designed to meet the requirements for large output and high precision, which is widely used in chemical industry, metallurgy, non-ferrous metal, ferrous metal, food industry and abrasive materials etc. Square swing 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 swing screen is the reciprocating inertia force formed by the rotation of eccentric wheel winding the dead axle. According to the structure characteristics and working principle of swing screen, its screen surface is arranged with level or incline ( the angle of inclination is 0° ~5° |. working principle of swinging screen is that after starting the screen machine, the shaking body of screen machine namely screen box make reciprocating motion under the action of the inertial force, screen box drives screen surface to make periodic shaking, which makes the material on the screen surface to make directional jumping movement with the screen box. During the period the material smaller the aperture of the screen surface fall to under layer through the sieve mesh to become the screen underflow. The material bigger than the aperture of the screen surface is discharged from the discharge gate after the continuous roll jumping movement and finally complete screening work. From the structure and working principle of FYBS1 square swing screen can see that the resident time of material staying on the screen surface namely the distance of its drive mechanism eccentric wheel apart from the motion trail of material has a very important influence, that is to say having the opposite effect to processing capacity and screening efficiency of screening machine. To this end, in actual screening assignments, we can make our choices in the two aspects of production capacity and screening efficiency. With the same or similar configuration, FYBS1 type swing screen have higher processing ability and the screening efficiency than the general inertia vibrating screen, the models can artifically control the material in the screen surface movement and residence time, because the materials’ movement speed and acceleration are to change nonlinear curve, therefore, materials and the screen surface had more chance to contact, of course also increase the screening rate. 1 Automatically high-efficiency self-cleaning of the screen mesh 2 Wire cloth with high use ratio and durability 3 Good sealing Overall Diagram Material Operation Schematic Diagram Chemical industry: fertilizer, resin, melamine, soda ash and so on.
