Working principle of Wall Plaster MachineAfter the bulk material is broken, it is sent to the silo by the lift, and then evenly sent to the main grinding chamber by the electromagnetic vibration feeder. Material entering the grinding chamber is scooped up and placed between the grinding roller and the ring to be ground. After grinding, the fan blows air into the grinding chamber, and the powder is blown into the analyzer for sorting.
