What is the difference between the upper and under attracting bin pump?
From the factor of mixing ratio, same amount of delivery, same mixing ratio, the speed of under attracting delivery is low, of course the premise is to meet the minimum conveying speed, and the delivery pressure is low as well. In this way, from the points of reducing wear and consumption, under attracting type is favorable.
From the material flowing form,there is fluidized process in the upper attracting, material and gas mixed equally, then delivery is stable.
The two type of bin pump can both use coal powder ash as removal material, but the fluidity of some materials is poor. it is not suitable for upper attracting delivery.
