Screw Conveyors

PSSILO Screw Conveyors are designed for controlled horizontal or inclined transportation of grain, feed and suitable bulk materials within storage, feed production and processing facilities.

The rotating screw moves the product continuously through an enclosed conveyor body, providing a compact conveying solution for applications where controlled product transfer, multiple inlet or outlet points and efficient integration with other equipment are required.

Each conveyor is configured according to the product characteristics, required capacity, conveying distance, installation angle and process requirements.

HORIZONTAL & INCLINED CONVEYING

Screw Conveyors can be configured for horizontal or inclined product transportation according to the plant layout.

Their compact construction makes them particularly suitable for applications where installation space is limited or where material must be transferred between closely connected process equipment.

The final configuration is selected according to conveying distance, elevation difference, product characteristics and required capacity.

ENCLOSED PRODUCT TRANSFER

The enclosed conveyor body keeps the product contained throughout the conveying process.

This configuration helps reduce product spillage and limits the release of dust into the surrounding working area during transportation.

For dusty products and indoor processing facilities, enclosed conveying can provide an important operational advantage compared with open transfer methods.

PROJECT-SPECIFIC SCREW DESIGN

The performance of a Screw Conveyor depends on correct selection of the screw and operating parameters.

PSSILO determines the conveyor configuration according to:

• Required conveying capacity
• Product type
• Product bulk density
• Conveying distance
• Installation angle
• Inlet and outlet arrangement
• Upstream and downstream equipment
• Operating conditions

Screw diameter, pitch, drive system and conveyor dimensions are selected according to the requirements of each project.

MULTIPLE INLET & DISCHARGE OPTIONS

Depending on the process layout, Screw Conveyors can be configured with different inlet and discharge arrangements.

This provides flexibility when transferring product between silos, bins, dosing systems, mixers, processing machines and other equipment.

The number and position of inlet and outlet points are determined according to the required product flow and plant configuration.

COMPACT SYSTEM DESIGN

Screw Conveyors require relatively limited installation space and can be positioned directly below or between process equipment.

This makes them suitable for applications such as:

• Silo discharge
• Hopper and bin discharge
• Feed mill transfer
• Dosing systems
• Mixer feeding and discharge
• Grain cleaning lines
• Processing equipment connections
• Short-distance bulk material transfer

CONTROLLED PRODUCT FLOW

The screw mechanism provides continuous and controlled movement of the transported product.

When correctly sized for the application, the conveyor can provide stable feeding to downstream equipment and help maintain consistent material flow throughout the process.

This is particularly important in dosing, mixing and processing applications where controlled feeding affects overall system performance.

DURABLE & MAINTENANCE-FRIENDLY DESIGN

PSSILO Screw Conveyors are configured for reliable operation in industrial grain and feed handling applications.

The conveyor body, screw, drive system, bearings and supporting components are selected according to the product, capacity and operating conditions.

Maintenance access and component arrangement are considered during project design to support practical inspection and servicing.

SYSTEM INTEGRATION

PSSILO Screw Conveyors can be integrated with:

• Grain storage silos
• Feed silos
• Hoppers and bins
• Chain conveyors
• Belt conveyors
• Bucket elevators
• Grain cleaners
• Mixers
• Dosing systems
• Feed mill equipment
• Filling and discharge systems

This allows the Screw Conveyor to operate as part of a complete material handling and processing system rather than as an isolated machine.

AUTOMATION & INTERLOCKING

Screw Conveyors can be integrated with the plant PLC & SCADA automation system.

Depending on project requirements, the control system can coordinate conveyor operation with upstream and downstream equipment, including:

• Start and stop control
• Equipment status monitoring
• Alarm and fault monitoring
• Equipment interlocking
• Product routing
• Process sequence control

This helps maintain coordinated product flow throughout the complete plant.

WHY PSSILO?

Selecting a Screw Conveyor requires more than choosing a nominal capacity.

Product characteristics, bulk density, conveying distance, installation angle, inlet and discharge arrangement and connected equipment all influence conveyor performance.

PSSILO evaluates these parameters together and configures the Screw Conveyor as part of the complete material handling process.

Integration with silos, conveyors, bucket elevators, dosing equipment, mixers and automation systems provides a coordinated conveying solution designed around the actual operating requirements of the facility.
