Abstract：When the sand and gravel aggregate production line adopts a mobile belt conveyor automatic loading system for loading,the mobility of the belt conveyor makes it difficult to effectively arrange the dust collector,resulting in poor dust removal effect.The mobile ventilation duct moves with the belt conveyor can convert mobile dust removal into fixed dust removal,achieving efficient dust removal during loading.This article introduces the production process of the automatic loading system of the mobile belt conveyor,the structure and working principle of the mobile ventilation groove,and the selection design of air volume and air pressure for dust removal.When using a mobile ventilation duct for dust removal in the loading system,the gas velocity of the mobile ventilation duct should be controlled at 20～22m/s,and the gas pressure of the dust removal fan should be more suitable than 4000Pa.In practical applications,equipment sealing should also be strengthened,and regular dust cleaning treatment should be carried out.
