At the same time, overflow type ball mill also has a spiral inside the discharging pipe. The direction of the spiral is opposite to the running direction of cylinder body, which can prevent steel balls and ores from being discharged out of ball mill. However, it has low capacity and is easy to over-crushing. The quill shaft adopts cast steel part and the liner is detachable. The turning gearwheel adopts casting hobbing process and the drum...
