Introduction
A screw conveyor (also known as spiral conveyors,conveyor screw,auger conveyor)is one of the most versatile and cost effective mechanical conveyors for handling dry bulk solids such as flakes, grains, powders, seeds and granules. The conveyor provides enclosed transfer while moving materials-horizontally, vertically or at an incline and can deliver materials from one or more inlet points to one or more discharge points. It usually consist of a trough or tube containing either a spiral blade coiled around a shaft, driven at one end and held at the other, or a "shaftless spiral", driven at one end and free at the other. Screw conveyors can be operated with the flow of material inclined upward. When space allows, this is a very economical method of elevating and conveying. As the angle of inclination increases, the capacity of a given unit rapidly decreases.
Application
Screw conveyor widely used in chemical, metallurgy, paper making, and construction industries. The equipment is mainly suitable for field flowing work, such as concrete mixing station, bulk material transit storage, etc.
Working Principle
New Type U Type Spiral Conveyor Screw Conveyor 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 flexible spiral conveyor eliminates thea 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.
Features
1.No pollution:
Flexible auger machine with totally-enclosed structure without causing any environmental pollution.
2.Widely application:
Construction available in mild steel and stainless steel so flexible auger machine can widely used for all kinds of material
3.Easy to installed:
With simple structure so flexible auger machine easy assembly and replacement of component parts.
4.Easy maintenance and low operating cost.
5.Multiple inlets and outlets.
Flexible auger machine with multiple inlet and outlet,so it can mix material and unload material at any points
