Design and experimental analysis of mine energy-saving two-stage vibrating screen

Abstract: In order to study the energy-saving characteristics of the mining vibrating screen from the original structure, the information of the design stage of the mine energy-saving two-stage vibrating screen is lacking and can not be quantitatively evaluated. The black box method is used to design the scheme, and the scheme combination model is established. The functional analytic method establishes the optimal solution model of the scheme combination evaluation, and uses the dynamic programming method to find the optimal structural scheme combination of the mine energy-saving two-stage vibrating screen. The scheme design of the energy-saving two-stage vibrating screen is completed according to the optimal solution of the scheme. , digital prototype development and product prototype manufacturing. In order to verify the design feasibility, the prototype was subjected to vibration test. The test results show that the double-stage sieve is 37.8% more energy efficient than the traditional sieve of the same specification, and the design of the scheme is reasonable.
