After the screen machine of the swing screen is started, the screen box makes an approximate circular motion under the action of vibration force, driving the screen surface to make periodic movements, so that the materials on the screen surface make directional jumping movements together with the screen box. During the movement, materials smaller than the screen pore size fall to the lower layer and become under-screen materials. Materials larger than the screen pore size are discharged from the discharge port after continuous jumping, and the screening work is finally completed. The swing screen is a classic and universal inertial screening equipment with mature technology. Judging from the running trajectory of the vibrating body of the screen machine, the swing screen is a non-linear inertial vibrating screen. Its new design concept and unique structure make it the screening machine closest to manual screening operations, achieving an almost perfect screening effect of the swing screen and having broad application prospects.
From the motion trajectory of the screen box From the point of view, the swing screen is also called a compound rotary screen. The vibration force generated by the swing screen driving device is an inertial force that changes regularly around a fixed axis. Its essence is the centrifugal force formed by the rotation of the eccentric mass around the fixed axis. The strong applicability of the swing screen determines that it can be used for both dry screening and wet screening. The swing screen has the advantages of unique structure, long service life, easy installation, good sealing effect, high screening accuracy and easy maintenance. It is precisely these advantages that determine that the swing screen is widely used in the grading and processing of fine materials in mining, building materials, metallurgy, casting, abrasives, chemical industry, light industry, medicine and food and other industries.
The role of the swing screen in the food industry The application is particularly outstanding, and this is also the greatest contribution that the swing screen has made to our human society. The requirements of the food industry are quite strict, mainly in terms of screening accuracy and hygiene. Hygienic conditions are related to the safety of our human lives and require our great attention. Relevant national laws also have very strict requirements for the food industry. For example, screening equipment must be made of steel, and the inner and outer surfaces of the screening equipment must be polished. Our country will further take corresponding measures to severely crack down on illegal activities and further improve the requirements for the food industry. In addition, despite the requirements for screening accuracy, the higher the screening accuracy, the more delicate the screened materials will be, and the corresponding taste of the produced food will be more delicate. Among the many screening equipment in the screening industry, only the swing screen can meet the requirements of screening accuracy and strict sanitary conditions at the same time. In the future development process, my country's screening industry will continue to improve our country's swing screens so that they can screen more fine materials and set new highs for my country's food industry.
