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 .Screw conveyor is divided into shafted screw ( see pic 1)  and shaftless screw ( see pic 2)  .

 

●  image002.jpgPic 1   .standard sectional flight screw : most common. Used to convey a wide variety of products

●  image004.jpgPic 2  .shaftless Screw : Similar to ribbon screws,used for conveying sticky,gummy or viscous substances,or where the material tends to stick to the flighting at the pipe.Also used with stringy products that would typically wrap around the screw pipe .

And shaftless screw conveyor is our topic here .


Structure

Shaftless screw conveyor is made up of trough casing, cover, shaftless screw flight, liner, end plate, gland  packing, bearing and geared motor. There is no solid shaft inside the casing .

Working principle

1.shaftless screw conveyor adopts no shaft revolving inside the casing, little touching materials’ size,low friction,no blocking or twine.

2.Sludge will be fed into feeding point, then pushed by screw flight to the discharging point, at last complete the transporting process.

3.Screw flight is strong thick to push sludge or other materials, long time for usage. Support base is made of U shape, strong strength, with detachable cover so as to watch the working condition of sludge inside shaftless screw conveyor .

4.There will be some liners which is fixed inside the bottom of casing. Liners are made of steel or plastic .Most time we choose hard wearing materials to do liners .Such as nylon and UPE. Nylon is more cheaper .UPE is more reliable for withstand wearing working .


Durability

1.Usually the shaftless screw conveyor will work more than 2 years at least on condition that there is no quality problem .

2.Complete set of shaftless screw conveyor’s using time is no less than 10 years .

3.Make annual check as per year .Electrical components’ using time is no less than 2 years.Motro &gearbox’s using time is no less than 10 years .Bearing’s using time is no less than 2 year .


Application

Feeding ,discharging and mixing for conveying sticky, gummy or viscous substances, or where the material tends to stick to the flighting at the pipe or shaft.

 

Installation Request on Job site

 1.Installation base shall be completed in advance ( at least 20 days before shaftles screw conveyor  arrival).Such installation base shall have enough ability to support and can guarantee shaftless screw conveyor will not sink and change because of the over small installation base. And ensure there are enough stability to support the  shaftless screw conveyor

2.Must clean any dust or dirty points on shaftless screw conveyors.Clean out all dust and dirty points during packing or shipping .

3.Can put some asbestos between machine casing and flanges,so as to adjust the deviation on shaftless screw conveyor’s length.


Maintenance

Check regularly each component ‘s working condition on shaftless screw conveyor .Pay attention to any loosing  fastener. If find the loosing fasteners, tight them up and fix them well .


Package and Shipping

By export plywood case or steel frame, suitable for shipping by sea .

If there is no any urgent request, all shaftless screw conveyors are shipped by sea .


Service

1.We will send manual book with specification to the final buyer .Final buyer will install and maintain the shaftless screw conveyor as per manual book .

2.Can send engineers to give instructions about installation work on job site .The guiding cost will be calculated as per the actual time on job site .

3.Can send engineers to train workers on job site .The guiding cost will be calculated as per actual time on job site .

4.Can send workers to install screw feeder conveyors as per contract .Installation cost will be included in the contract .
