There exist a layer of lining plate : carbon steel ,nylon or UPE between screw flights + shell. Most time we choose nylon material or UPE as lining plate. Because the nylon and UPE can prevent the screw flight from high abrasive .
The following shaftless screw conveyors are used to transport sticky sludge waste in Thailand on an environmental project.
If quantity of shaftless screw conveyor reaches 5 sets or 10 sets, we choose steel frame to pack .See an example photo as below :
If length is less than 6000mm, we use 1 set of 20ft container .
If length is beyond than 11800mm but less than 12000mm,we use 1 set of 40ft container .
If quantity of shaftless screw conveyor is 1 or 2 set ,we choose plywood case to make packing.
We can deliver the plywood case to Shanghai warehouse directly . Or customer can send his driver to pick shaftless screw conveyor up at Wuxi Changrong Conveying Machinery Company.
