These issues insieve outstanding performance meoff beam, crack help, lubrication oil dilute the box-type vibrator oil spills, fighting tooth gear, bearing temperature rise too high, major issues such asnoise, panied bydancing with broken belts, such asfault zone. Such issues directly affecting the life ofthe shaker, which has seriously affected the production. 2YAH1548-round good shaker can solve such problems, so this shaker designed for round 2YAH1548-shaker, the series ofmajor shaker inthe materials used inthe coal industry classification, dehydration, desliming, such asreferrals from Operations. Its reliable, efficient screening, but their heavy equipment. Design analysis onthe design options, including the classification and shaker features and design programmes tobeconfirmed; materials onthe movement ofthe shaker and the dynamics ofthe parameters, todesign the structure ofvibrating screen size; conduct The eccentric block ofthe exciter, such asdesign and calculation, including the original design parameters, motor design and verification; were the ponents ofthe design and calculation, belts and check the design and calculation, the design ofspring, the axis ofStrength, the choice of bearings and calculation and then proceed tothe maintenance ofequipment, installation, lubrication and seal the design, ashaker f
