The Screw Conveyors are also known as Auger screw conveyor, which works on the principle of moving the materials from one place to another. They are the basic equipment for bulk material handling. A screw conveyor works on the mechanism that uses a rotating helical screw, called auger screw conveyor flights, that is installed within a tube or trough, to move liquid or granular materials.

Auger screw conveyor parts 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 called a solid shaft screw. Other types are open helix or shaftless screws driven at one end and free at the other.

The rate of volume transfer is proportional to the rotation rate of the shaft. In industrial control applications, the device is often used as a variable rate feeder by varying the rotation rate of the shaft to deliver a measured rate or quantity of material into a process.

Application of Screw conveyor

Industrial application of Screw conveyors is often used horizontally or at a slight incline, providing movement. They are capable of moving semi-solid materials, including food waste, wood chips, aggregates, cereal grains, animal feed, boiler ash, meat and bone meal, municipal solid waste, etc.

The screw conveyors are economical as well as, can be accommodated in small space, allows, utilizing an inclined screw conveyor for elevating or say conveying material. The angle of inclination as per the rule of thumb is 45 degrees or less, otherwise, the material will end up falling backward over the flighting and not conveying to the desired destination.

Screw conveyors are versatile and one of the most reliable cost-effective to convey a wide variety range of bulk material from dry free-flowing to wet sluggish dewatered biosolids.

Screw auger conveyor designed to operate in any position, whether horizontal or vertical. properly designed serve the purpose for many years to come uninterrupted, increasing the productivity

HOW TO KEEP SMOOTH AND EFFICIENT MOVEMENT OF AUGER CONVEYOR

An Auger Conveyor is the ideal way to move the raw materials from one working area to the other.  If used commercially, the Auger Conveyors are efficient.  There are various reasons, which may lead to spoiling and malfunctioning. The problem arises due to  :

Dust: As we all face and suffer from dust. The same may lead to a serious hazardous condition in the workplace, for employees as well as for conveyors, where it is caused due to the movement of powders or finely ground materials.  In such conditions, here it is required to use suitable seals and gaskets, which must be highly compressed,  along with the flanged covers, which provide additional protection from dust. Here average seals may fail.

Abrasive Material:  In industries, where cement, sand, concrete, etc, are required to be moved or say abrasive material is moved, it may lead to the wear and tear of the Auger conveyor.  Here, highly carbon abrasive resistant steel alloy or nickel-based alloy along with chromium and molybdenum prove successful. They increase the resistance power to deal with corrosion and abrasion. The use of coated shafts and troughs also helps fight abrasion, increasing hardness. This will help increasing life expectancy and reduce maintenance problems, arising due to them.

Clogging of auger conveyors: Another factor, which leads to a serious problem is ‘clogging’. It arises, where sticky or wet material is required to be moved.  In such cases, it is better to add mild heat to the auger for easy and better movement of material.  In such cases, where heat is required should be constructed of stainless. Another way is to go for shaftless screw conveyors to prevent clogging. Cheese is one of the materials that slide much easily through a heated auger system.

Applications of auger screw

perfect designed Auger Conveyors may add to less downtime, high productivity, wastage, waste of time, less maintenance, etc. It is advised to better go for tailored-made auger conveyors, for successful working. Neo Auger screws are highly in demand due to their best appropriate design and specifications.
