We have been involved in designing and making screw conveyors since 1985 ,then founded Wuxi Changrong Conveying Machinery Company in 1993.Screw conveyor is one of the best conveyors to transport powder, particle and granules .Sometimes ,there will be some materials bridged or jammed in the upper big silo or large tank .Certainly there will be some electrical valves or pneumatic valves under the bottom of silo or tank ,but they still can not solve the bridging problem .Some materials still remain in the middle of silo ,never dropping down .In such occasion ,we develop the vertical screw conveyor shaft inside the silo ,to revolve in vertical direction, making materials dropping down smoothly and evenly. Such device are called arch-breaking machine . When it stop working ,it can lock materials .The size of arch-breaking machine is subject to the silo’s size and capacity .Sometimes, the vertical screw conveyor can replace the hopper wall vibrator.

Installation Request on Job site
1.Arch-breaker machine must be vertical to the silo .Ensure the silos’ casing thickness is enough to support the stable working .If silos casing’ thickness is very thin,it will cause silo transformation and make the shaft impact the silo casing .
2.Clean all dirty on arch-breaker machine before installation .
3.All connection screws and bolts shall be tightened to the reliable degree.
4.Check all oil’s place and make sure there are enough lubrication oil there .
5.The concentricity of main shaft and sprocket’s shaft are same .
1.All bearings are under dust.Wuxi Changrong take measures to set up the framework oil sealing to prevent all dust or materials from getting into bearings .Turn on the air valves before turn on the arch-breaker .
2.Stop feeding materials first .Only all materials are discharged out can stop the arch-breaking machine .
3.No big size materials dropping into the arch-breaking machine .So as to protect arch-breaking machine from being jammed .
4.Stop the arch-breaker as soon as any abnormal conditions.
5.Drive device’s maintenance is as per its manual book.
