However, after the valve is opened, the opening set on the automatic control is maintained, and the powder is discharged too quickly and cannot be collected in time. For large-scale production, if the dry paste powder is not collected in time, a lot of waste will be caused. If the hopper mixer is improved and a quantitative control device is introduced, the cost is too high. Utility Model Content
