SCREW FEEDER & CONVEYOR

Our clients can avail from us a wide assortment of Screw Conveyors and Feeders. These conveyors are widely used for various purposes like cement screw conveyors and feeders find applications for concrete batching plants ever since 1970s. The light-duty flour milling screw conveyors come integrated with synthetic maintenance-free intermediate bearings and are highly durable. We also offer robustly constructed heavy-duty cement screw conveyors that feature self-adjusting stuffing boxes that find widespread usages across the cement industry. Further, extra-heavy-duty screw conveyors that feature flanged shaft couplings for easy screw replacement and are designed for meeting the diverse applications in cement, lime and gypsum processing can also be availed. The shaft-less screw or spiral conveyors offered by us, integrate ultra-heavy-duty helicoids flighting abilities that ensure efficient handling of high moisture containing material (sludge or screenings), which get stuck to the center pipe or flight in traditional screw conveyors. Moreover, with rich experience in the domain of screw feeding, we are able to develop precision-engineered screw feeders for both micro-feed rates and large volumes. The range offered by us features feeders with agitator tools, feeders with flexible troughs to facilitate in gentle massaging and blending of material, feeders for steep angle applications and many others. Furthermore, with our worldwide network of sales and service subsidiaries, we are able to excellent installation services for the same.  

DESCRIPTION
The system cosists of:
- BFS Horizontal Screw Feeder
- BVS Vertical Screw Conveyor
- BIS Injector Screw

The BFS Screw Feeder receives the material from the mixer/hopper and transfers it to the BVS Vertical Screw Conveyor. The BFS Screw Feeder is a discharging equipment provided with optional inlet spouts which are pre-engineered to suit the most commonly used mixers on the market.

The BVS Vertical Screw Conveyor receives the material from the BFS Screw Feeder through a tangential or frontal discharge port. The BVS Vertical Screw Conveyor lifts the biomass to an appropriate height where it feeds it into the BIS Injector Screw.

The BIS Injector Screw collects the bulk material from the BVS Vertical Screw Conveyor and injects it into the digester below the liquid level.
FUNCTION
The TCB Bulk Biomass Conveying System is a complete and versatile screw conveyor system which extracts the bulk fraction of the biomass from the mixer/hopper, lifting and charging it into the digester of the biogas production plant.

We are prominent manufacturers, suppliers and exporters of Chain Conveyors that are developed to handle the conveying of dry solids like free flowing powders, granules, pellets and flakes. These conveyors come in hot galvanized flanges, casings that feature tail & head sections containing drag and transmission roller, as well as numerous modular intermediate sections. Further, the drive unit is attached on the drag roller using a direct geared motor or a chain transmission to boost the performance. The conveyor chains can be manufactured from blank and bent links or forged with pressed links to suit the type of material handled and the throughput rate. Moreover, Polyzene® or manganese steel fabricated chain guides can be offered to match the application specific requirements of the clients.

 

The SSC Shaftless Screw or Spiral Conveyor is an alternative concept to the traditional shafted screw conveyor. Material is conveyed by an extra-heavy-duty shaftless screw that slides on a low-friction, wear-resistant liner inside the conveyor trough housing.
The U-section troughs, which are longitudinally divided, are manufactured in carbon steel or in 304 L / 316 L stainless steel, including an appropriate surface treatment. Fabricated parts except the screw, which is ultra-heavy-duty, are of the medium-heavy-duty type. The cross section of the lower part of the trough is slightly wider than the side channels to allow for the liner to be inserted in the lower trough part. After complete assembly of the trough the liner is kept in place by the upper trough side channels. At one trough end there is a vertical or flush-type outlet. At the drive end the screw conveyor is equipped with an end plate holding the end bearing assembly with flanged shaft coupling with the screw. The drive unit installed suits the application.
The SSC can be loaded from above into the open trough (standard), or through an inlet spout included in a bolted trough cover (option), or from the side through a special side inlet in the loading zone of the trough (option).

The VE Vertical Screw Lift System consists of a horizontal screw feeder and a Vertical Screw Conveyor.
The Horizontal Screw Feeder, which may feed material from a silo or hopper or simply convey it being fed by an upstream feeding device, consists of a U-shape or tubular trough in carbon steel with appropriate surface finishing. In any case the outlet zone consists of a short tubular section flanged at a right angle on the bottom section of the Vertical Screw Conveyor. A flange is welded at each end of the Horizontal Screw Feeder. The trough / tube contains a rotating screw with shaft coupling bushes at each end that are connected with the shafts of the two end bearing assemblies. The Horizontal Screw Feeder is equipped with one or more intermediate hanger bearings should its overall length require any. Furthermore, it is equipped with a drive unit suitable for the application.
The Vertical Screw Conveyor consists of a tubular housing complete with a tangential inlet in the bottom section which connects with the outlet of the Horizontal Screw Feeder, an inclined outlet spout in the top section, end flanges welded on each conveyor tube section, a rotating screw in one or more sections with shaft coupling bush at each end, a base bearing assembly complete with slide bush, and a number of intermediate hanger bearings should the overall height of the conveyor require any. The top-mounted drive unit with integrated end bearing assembly (from which the screw is suspended) and self-adjusting shaft sealing unit is suitable for the application.
The VE Vertical Screw Lift System is available in a medium-heavy-duty version only.
