Bucket elevator conveyor is applied for the vertical transportation of lead powder and granular in battery industry. Lead powder has a poor liquidity, and slightly with water sometimes. Thus, the lead powder vertical lifting machine uses “take out” way of feeding and loading. On the basis of the material characteristics, it adopts centrifugal-gravity way of unloading. With the shallow bucket interval arrangement, their speed theoretical value is at the range of 0.7-1 m/s, this helps to material unloading.
Given the material size and water content factors, the proper speed of the bucket elevator needs to be changed in the continuous exploring. The suitable speed keeps pace with the material, makes the bucket elevator achieves continuous work, with no leakage and no material blockage.
Lead granular is the smooth cylinder of fixed size, so this kind of bucket elevator uses “flow-in” way of feeding and loading. It adopts deep bucket inclined feed version, the distance between bucket side edge and tank wall less than the material minimum size to prevent material scattering. The materials for gravity discharging, with speed within the range of 0.7 to 0.8 m/s.
