External Motor Sweep Auger
According to the mandates of GB17440, which delineate "Grain processing, storage, and transportation system dust explosion-proof safety Regulations," silos are classified under the dust explosion-proof 20 zone environment in China. Consequently, all electrical apparatus within these silos must adhere to the stringent guidelines applicable to this environment. Presently, the vast majority of traditional sweep augers feature motors situated internally within the silo, necessitating upgrades to dust explosion-proof 20 zone compliant motors. Unfortunately, such motors are non-existent on both domestic and international fronts, compelling numerous companies to resort to sweep augers equipped with motors designated for dust explosion-proof 21 zones. This substitution introduces potential safety risks.
Consequently, addressing the challenge of averting safety risks posed by equipment with electric motors positioned inside silos has emerged as a pivotal technical quandary for industry specialists.
The innovative research team at Hongrui has devised a groundbreaking solution by developing the external motor sweep auger. This design not only mitigates explosion risks but also upholds operational efficiency.
