CIRCULAR MOTION VIBRATION SIEVE OF AUTO CENTER

ABSTRACT

Vibration sieve is one of the most widely used devices in Coal Preparation Plant. Mainly used in coal preparation and the final screening with screening, But the vibrating screen is larger than the maintenance of equipment. With the gradual improvement of the design ，circular motion vibration sieve of auto center could well solve this problem. This article mainly introduced that vibration sieve in Coal Preparation Plant significance as well as vibration sieve development present situation, described this time has designed  circular motion vibration sieve of auto center design computational method basis and the step, as well as the main vibration sieve part's choice and the comparison, and showed this design characteristic. Including the classification and characteristics of vibrating screen and determination of design; on the movement of materials analysis, Dynamic analysis of vibration sieve and kinetic parameters calculated, rational design of the structure vibrating screen size; carried out such eccentric Vibrator design and calculation, including the original design parameters, motor design and verification; were the main components of the design and calculation, calculation and check of belt design, spring design calculation, shaft strength calculation, bearing selection and calculation , then the equipment maintenance, installation, lubrication and seal design.
