Twin screw feeders introduction
Large volume twin screw feeder conveyors with breaking bars,best solution for breaking caking materials with large capacity.We have been involved in designing and making screw feeder conveyors since 1985 .Sometimes,there will be some materials built up or jammed in the upper big hopper.In order to solve the bridging and jamming problem,we design the twin screw feeder conveyors with breaking bar .There are 2 shaft inside on trough. Screw flights type can be chose as per materials’ feature .Please have a look at the following types of screw flights:
● 1.standard sectional flight screw : most common. Used to convey a wide variety of products
● 2.ribbon flight screw : used for conveying sticky,gummy or viscous substances,or where the material tends to stick to the flighting at the pipe.Available in integral style or post style ribbon.
● 3.cut flight screw : used for conveying light,find,granular or flaky materials .Also used for mixing materials in transit or for removing grit and dirt from the grain,cottonseed,etc.
● 4.cut and folded flight screw : used to create a lifting motion with the material that promotes agitation and aeration while mixing .
● 5.sectional flight screw with paddles : used to mix material while being conveyed.Paddles may be fixed ( welded in place ) or adjustable pitch ( bolt mounted,to provide different degrees of mixing )
● 6.used for complete mixing or stirring material .Paddles may be fixed ( welded in place) or adjustable pitch （bolt mounted ,to provide variable degrees of mixing )
● 7.short pitch screw : used primarily in incline or hopper fed applications where the pitch is less than the diameter of the screw
● 8.interrupted flight screw : as with a ribbon screw,used for conveying sticky,gummy or viscous substances,or where the material tends to stick to the flighting at the pipe,but offers better throughput and flow consistency than a ribbon screw .
● 9.Cone screw : Used to provide better “ mass flow “(uniform discharge) from a hopper or bin above than screws with variable pitch alone.
● 10.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 .
● 11.Typically surrounded by screens and used to press moisture from various products .
Let’s take a look at some details about shafted two screw conveyors as below :
Two shafted screw conveyor belongs to the small kind of material distribution machine.It works under a square or cone silo,distributing two shafts averagely. In this way,it not only can feed materials well ,but also can mix materials in a better way. Twin screw feeder conveyors applies in cement ,chemical starch,sludge,building material,gyspum powder.In job site ,there are many big silos connected working on the top of twin screw feeder conveyors .All materials are stored inside the silo ,then transported by the bottom twin screw feeder conveyors .

Installation Request on Job site
1.Installation base shall be completed in advance ( at least 20 days before twin screw conveyor with live bottom arrival).Such installation base shall have enough ability to support and can guarantee screw conveyor will not sink and change because of the over small installation base.And ensure there are enough stability to support the screw conveyor
2.Must clean any dust or dirty points on screw feeder 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 screw conveyor’s length.
1. Avoid any hard and big bulk material inside the transported materials,so as to prevent twin screw conveyor with live bottom from jamming.
2. Check regularly each component ‘s working condition on twin screw conveyor with live bottom .Pay attention to any loosing fastener.If find the loosing fasteners,tight them up and fix them well .
3. Must pay special attention to the bolt which is connecting with screw shaft.If find the bolt loose,must stop running immediately.Do not start working before tight bolts up .
After Sales Service
