ESP broken arch gas nozzle flow aid can help poor mobility within the silo accelerate the flow of materials, in continuous or batch operation, can be used alone, or with other broken arch device, method used together, so that the material in flow state silo surface layers are basically the same, to avoid the adverse flow separation agglomeration state, holes, bridge, etc. broken arch gas nozzle flow aid to be applied to large-scale mechanical mixing station. Aid flows broken arch cushion gas nozzle flow aids tried very wearable breathable polymer materials, compressed air through an area of ??about 100 square cm slowly seep into the hopper, the formation of local
