Analyzed large vibrating screen s dynamic characteristics of single channel and hyperstatic network structure and calculated natural frequency,natural mode of vibration and dynamic response based on finite element technology.

Thus it is an important research subject to design large vibrating screenings, raise the design level and improve working reliability and service life of vibrating screenings.

The Augmented lagrangian method was used in the dynamic optimal design of large vibrating screen to confirm the best position of reinforcing rib on the side plate,and the lower dynamic stress with the least number of reinforcing ribs was achieved.

Technological innovation and optimization design of oscillating screen;

Purified phosphogypsum is produced by use of previously idle equipment for aluminum fluorid production, with additional hydrocyclone by determining its optimum size of dust-setting nozzle(38 mm)and material (carbon steel with the 8～10 mm liner of ultrahigh molecular weight polyethylene (UHMWPE), as well as with additional oscillating screen for removing insoluble granular impurities and salts.

The reforming of screen bottom and screen surface of blast furnace oscillating screen has been done to use overhanging screennet technique in No.
