Digidale Engg. Co. is one of the most popular means of conveying.  Simple, cost effective and reliable.  The Screw Conveyor originated a long time ago and is an invention credited to Archimedes.  Nowadays with the use of modern be used  in almost any application.  The screw helix can be rolled from a strip of steel to form " Helicoids" fighting or discs are pressed allowing customized flight shapes in thick heavy duty steel.  All types of exotic metals can be  used  in order to resist wear or corrosion.  The simplicity of the device means many years of virtually maintenance free service.  Inclined or vertical the screw conveyor is a very inexpensive compact system for the elevation and transportation of bulk raw materials.

The key to any successful design is, a through understanding of the characteristics of the material to be handled.  This information must be available in order to evaluate the suitability of the screw conveyor to the application, taking into account the action of the screw on the material as well.

Typical applications include grain storage, feed mills, cereal processing and chemical plants.  Used for many mining and process operations they can be equipped with heating and cooling jackets.  Toxic materials can easily be handled with a screw conveyor because the enclosed trough or tube casing can be made tight enough to contain toxic dust or vapors and reduce hazards to the working and general environment.  The  material you intend to convey may even be damp or sticky, designs are available for most situations.

The Screw Conveyor has a constant volumetric capacity according to speed.  It may be exposed to a head of material and by having a correctly designed flight and with variation in the speed can be used to control and feed equipment at a uniform metered rate down the process stream, eliminating surges in the process.  In many situations it is the only device that can be used as a feeder.

A primary advantage is the number of feed inlets and discharge openings that can be provided.

SPECIFICATION :-

*   Long lengths may be achieved by the use of hanger bearings at intervals, however we prefer where possible to engineer these bearings out due to the maintenance requirements.

*  A full range of sizes for capacities from a few kg per hour kg per hour to 200 T / hr.

PRODUCT APPLICATION :-

* Ideal for conveying and feeding Grain, Coffee beans, Flour, Cement, Gyphum, Coal Salt, Sawdust, Woodchips etc.

* Full enclosed and adaptable to suit nearly all applications.

Screw conveyors are used for powder materials, with low powder coats and a minimum powder emission.  They can convey materials both on horizontal and high inclination, up to vertical conveyance.   The output of screw conveyors varies from few KGS upto 200 T / h. They are tubular or u through, according to the conveyance system required by the client.  Manufacturers DIGIDALE ENGG. PVT. LTD. is able to supply special screw conveyors with anti-abrasive flights or in stainless steel.  Transmission units are designed and realized by DIGIDALE ENGG. itself, which produce specific gearboxes for its  screw conveyors.  Under request, commercial transmission units of different brand can be assembled on the screw conveyors.   Shafts supports need a  minimum maintenance, assure low maintenance costs and
last longer.

Digidale Engg. screw conveyors have been designed to produce a dust tight method of transferring a  product from one point to another.  Utilising a rotating screw flight ( worm on pipe, auger ) the screw conveyors are available in a range of various constructions ranging from standard mild steel  ( suitable for the construction industry )

Digidale Engg. Screw conveyors have been designed to produce a dust light method of transferring a product from one point to  another.  Utilizing a rotating screw light ( worm on pipe, auger )  the screw conveyors to stainless steel 316 with crack and crevice free welding ( Suitable for the food / process industries ) Digidale Engg. screw conveyors will handle many materials easily and efficiently.  However, to ensure the best selection of components, we  recommend that careful consideration be given to the physical, chemical and handling characteristics of each product.

Tubular Screw Conveyors :- 

Tubular screw conveyors have been specifically designed for dust free conveying of a " free flowing" powder or  granular based product and are suitable for operation in almost any  industrial sector.  Produced in modular " plug in" sections the CTS screw conveyors are quick and simple to assemble and allow for conveying lengths of over 13m to be successfully spanned.
Availability in a wide range of standard diameters up to 500 mm ( with larger sizes on request ) and with several drive options allow capacity throughputs  of upto 250m³ / hour to be achieved.
Backed by comprehensive range of inlet / outlets and ancillary equipments the CTS conveyor can satisfy the most demanding applications.

THROUGH SCREW CONVEYORS :-

CUTS / CVTS Trough Screw Conveyors  :-

Digidale Engg.series of U / V trough screw conveyors have been designed for the dust free conveying, extraction and dosing of free flowing powders and granular based products.  Produced in a range of flight diameters and assembled from modular sections the CUTS or CVTS trough screw conveyor can convey materials in excess of 20m.  Available in a wide range of constructions  varying  from mild steel to 316 stainless steel with crack and crevice free welding, allows Digidale Engg. troughs to be utilized in most industrial sectors.

Other options include numerous flight designs, dust tight covers, bearings arrangements, drives, intake and discharge configurations.
