Vertical Screw Conveyor

Conveying & Feeding Equipment

Vertical Screw Conveyor

We specialize in design, manufacture, and supply of Vertical Screw Conveyors for vertically conveying various powders like Cement, Fly Ash and other dry powders. These Screws are manufactured with state of the art technology and machines imported from Europe.

The Vertical Screw Assembly system is a mechanical powder loading system which is preferred & recommended over the Pneumatic Loading systems and or Bucket Elevators due to its ease of use, lesser maintenance & compact size.

Product Description

The Vertical Screw Assembly consists of the Horizontal Screw Feeder which is installed below a silo or a hopper and as the name appropriately suggests it takes the feed from it. This Horizontal Screw Feeder feeds the powder to a Vertical Screw Conveyor. The Vertical Screw Conveyor is a tubular screw mounted at 90 deg to the Horizontal Screw Feeder to convey & elevate/ load the powder to the required height for filling into a weigh hopper and/ or one or multiple silos with a Distribution Screw (which is another Horizontal Screw Feeder installed at the top of the Vertical Screw Conveyor).

Also in a lot of rural parts of India where the raw material is sourced in HDPE bags and the facilities are not equipped for Pneumatic Loading our efficient & compact sized mechanical loading system which consists of the Vertical Screw Assembly & the Automatic Bag Slitting Machine serves as the perfect solution!
