Abstract:The funnels is the key part for the formation of bulk arch and congestion in the transport process.Because of the difficulty to precisely survey the physical features for different kinds of bulk, some anti-arch measures are necessary besides the theoretical requests for the inclinational angel and aperture in the design of the funnel. This paper selects the proper anti-arch measure and makes the bulk conveying fluently according to the requests of bulk physical features and funnel functions after analyzing some approaches such as mechanical stirring, atmosphere vibration, mechanical vibration, optimization of the funnel structure and adding liner in the funnel. The continuity and reliability in the process of bulk conveying and transport can be guaranteed by this anti-arch measure.
