Chemical industry: fertilizer, resin, melamine, soda ash and so on. Food: starch, salt, granulated sugar.milk powder, fish powder and so on. Metallurgy: ferrous metal, non-ferrous metal, magneticmaterial, metal powder, mineral and so on. » Working Principle; The chart below shows how the movement of materials on screen mesh and the residence time of materials can be artificially adjusted, and how FYBS2 swing screen realizes high efficiency screening process. Material movement trend and direction Speed and acceleration To pursue screening precision will sacrifice the output, pursuing big output will drop the precision. Weiliang FYBS2 swing (gyratory) 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. » Characteristics; 1 Automatically high-efficiency self-cleaning of the screen mesh 2 Wire cloth with high use ratio and durability 3 Good sealing Square swing screen is also called reciprocating screen. If see from the motion trail of screen boxri ne 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 FYBS2 square swing screen can see that the resident time of material staying F'he 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. Compared with the common type of inertia vibrating screen, FYBS2 swing screen has higher processing ability and higher screening efficiency, for that the movement of materials on screen mesh and the residence time of materials can be artificially controlled.
