Brief Introduction

U Shape Screw Conveyor , which is generally used in processing of food, pharmaceuticals, chemicals, minerals, ceramics, plastic and rubber. Its design is very simple & eliminates the need for any additional operating equipment such as filters or bearing. It consists of electric motor driven spiral, which is the only moving part, rotates within a food grade & sealed tube. The material moves along the spiral within the tube. The unique action of the Screw Conveyor eliminates the risk of the product separation that can take place in conventional pneumatic conveying systems where mixed materials have components of different densities and particle size.In fact,the conveying action ensures constant remixing.Conveyor maximum length can be upto 10 meters for material and may be  increased  or decreased inversely with bulk density.Vertical installation are also possible, but carrying capacity  decreases with increase in angle of inclination. Feed hopper is available in standard size or according to customers specification.


1. It is available in options of stainless  steel  or  mild  steel  /  painted.  for most applications, flat : for fine powder. proscrew : for difficult material.

2. Dust free, Easy to Clean, high & low level control, safe & hygienic handling.

3. Accurate metering and high transfer capacity.

4. The main advantage is to low on installation & maintenance costs and high on efficiency and performance.
