Vertical Screw Conveyor

Vertical Screw Conveyor

Varahi Industries’ Vertical Screw Conveyor lifts bulk materials vertically for efficient transfer of powders, granules, and particulates from lower to higher levels. Rotating helical flights within a U-trough or enclosed O-tube ensure smooth, controlled conveying at steep/vertical angles.

The screw is mounted on a central shaft and driven by a gearbox–motor set; an optional VFD allows speed tuning to suit bulk density, flow characteristics, and process requirements. Compact, low-maintenance, and energy-efficient—ideal for continuous lifting operations.

Working Principle

Design & Construction

  • Central shaft with precision-formed helical flights (variable pitch available).
  • Configurations: U-trough or enclosed O-tube for dust control.
  • Heavy-duty bearings, gland/shaft seals, and robust end plates.
  • Gearbox–motor drive with safety guards; inspection/clean-out ports.
  • Materials of construction: MS, SS 304/316 per hygiene & corrosion needs.

Options & Controls

  • VFD for speed control and gentle handling of fragile products.
  • Dust-tight covers, venting, and optional liners for abrasive materials.
  • Load/level sensors, interlocks, and feed-rate synchronization.
  • Easy-clean design with removable sections and quick-open covers.
