Screening mode 1, swing-style screening: Two same pore size screen, so the screen once again screening material in order to achieve higher screening accuracy. 2, convolution reverse screening: screening material from fine fine → → → coarse manner in screening, crude materials play a role in cleaning the mesh. 3, double screening process: evenly distribute the material into the screening machine to screen swing on two levels, so that a single screening machine processing capacity to nearly double, a two-screen machines when used. 4. Combined screening: general screening + convolution screening, increase the utilization of a single-screen machines. Rocking vibration sieve sieve and repair rate and service life compared to using a high-speed shaker vibration theory, mechanical vibration was present there is very destructive, a long time prone to cracking or deformation of the vibration phenomenon, often screen The damage was not caused by normal wear and tear, but the shaker vibration itself caused by friction. And the noise is relatively large, the motor and vibration sieve using a vibration motor, vibration motor relative to General Motors, its short life metal fume dedicated swing sieve, maintenance is higher. Swing screen uses a low-speed swing principles ensure the life of equipment, reduce maintenance costs, reduce equipment noise, and equipment more secure.
