SYORITEC – Screw Conveyors & Feeders

Reliable and efficient solutions for transferring bulk materials in industrial processes

Product Description

SYORITEC screw conveyors are mechanical conveying systems engineered for the controlled transfer of bulk materials such as powders, granules, flakes, pellets, and fine particulate solids.

They are widely used for:

  • Silo discharge

  • Bunker feeding

  • Dosing and metering

  • Jet filter dust extraction

  • Mixer and blender feeding

  • Packaging and weighing systems

With their modular design, robust construction, and wide range of material options, SYORITEC screw conveyors ensure continuous, safe, and high-performance conveying in demanding industrial environments.

Operating Principle

The screw conveyor functions through the rotation of a spiral flight (helix) welded onto a shaft, driven by an electric motor and gearbox.

  1. Bulk material is fed into a U / V trough or pipe

  2. The rotating helix pushes the material forward through progressive linear movement

  3. The material is discharged from one or multiple outlets as required

This simple yet highly efficient mechanism provides continuous conveying in horizontal, inclined, or vertical directions.

Construction & Materials

Trough / Pipe Materials:

  • Carbon steel: ST37, ST52

  • Wear-resistant steel: Hardox 400–450

  • Stainless steel: AISI 304, 316, 310

  • Food-grade stainless steel options available

Screw Flights:

  • Carbon steel

  • Hardox anti-abrasive steel

  • Stainless steel AISI 304 / 316

  • One-piece or segmented construction

Sealing Options:

  • Teflon seals

  • Viton seals

  • Packing gland (salmastra)

  • Mechanical seal

Bearings & Supports:

  • End bearings

  • Intermediate hangers for long conveyors

  • Heavy-duty shaft supports

These options allow SYORITEC conveyors to operate efficiently under different temperatures, abrasion levels, capacities, and product characteristics.

Types of SYORITEC Screw Conveyors

1) Pipe Screw Conveyor

Fully enclosed conveying with zero spillage and maximum hygiene.
Ideal for:

  • Fine powders

  • Food applications

  • Chemical and plastic processing

  • Dust-sensitive materials

2) U-Type Screw Conveyor

The most versatile and widely used design, featuring an easy-to-open top cover and simple maintenance.
Applications include:

  • Silo and hopper discharge

  • Weighing and dosing systems

  • Mixer and blender feeding

  • Packaging units

3) V-Type Screw Conveyor

Specially designed for dust collection systems such as:

  • Jet pulse filters

  • ESP electrostatic filters

  • Dust hoppers and settling chambers

Allows multi-point discharge and efficient dust management.

4) Shaftless Screw Conveyor

Designed for handling:

  • Sticky

  • Viscous

  • Wet

  • Fibrous

  • Compacting materials

Used in wastewater treatment, sludge conveying, and difficult industrial materials.

5) Dosing Screw Feeder

Ensures accurate, stable, and low-capacity feeding of fine materials.
Suitable for:

  • PVC powders

  • Chemical additives

  • Food ingredients

  • Pharmaceutical powders

6) Vertical Screw Conveyor

Transfers materials from lower to higher levels within a compact installation area.
Ideal for silo filling, vertical feeding lines, and high-level transfer points.
