What is Auger Conveyor?

Auger conveyor can convey horizontally, inclinedly and vertically.

Auger conveyor consists of a helical screw rotating inside a closed tube or an open U-shaped tube, the material is fed through the inlet of the screw conveyor, passed through the conveyor by the rotating screw conveyor, and taken out through the discharge end. The Auger conveyor is capable of conveying powdery, granular, lumpy, and even stagnant products, such as food waste, wood chips, aggregates, grain, feed, municipal solid waste, etc., at any angle from horizontal to vertical, and can be permanently installed or portable, And there are a variety of sizes and configurations to choose from.

Working Principle of Auger Conveyor

When the screw shaft of the auger conveyor rotates, due to the impetus of the blades, at the same time, under the action of the material's own gravity, the friction between the material and the inner wall of the material tube, and the internal friction of the material, the material slides relative to the spiral blade and the material tube. The form moves forward in the material pipe to complete the conveying of the material.

Structure of the auger conveyor

The main components are: driving device, end bearing seat, screw shaft, spiral blade, end feeding port, middle feeding port, middle bearing seat, head end bearing seat, middle discharge port, first end discharge port, machine slot, etc.

Auger conveyor parts

Drive device: It is the power part, divided into single drive and double drive. The drive motor is suitable for 380V, 3-phase, 50Hz, its protection grade is IP55 (outdoor type), and the insulation grade is F grade. The gear reducer is composed of high torque, low noise and no oil leakage.

Bearings: including first and end bearings and intermediate bearings. The first and end bearings are arranged outside the machine slot, which is convenient for installation and maintenance, and at the same time prevents dust from entering the bearings.

When the auger conveyor is too long, it is usually assembled in multiple sections. When it exceeds 3-4 meters, an intermediate bearing, also called suspension bearing, should be installed. Its main function is to bear part of the weight and operation of the screw shaft. The force generated at the time.

Machine groove: used to support screw shafts, intermediate bearings and conveying materials.

Spiral blades: Choose carbon steel, stainless steel and manganese steel according to the material. For the conveyor's viscous and winding materials, shaftless spiral blades can be used.

Benefits of Auger Conveyor

Large conveying capacity

It allows to transport a large amount of materials in a small space, with a conveying capacity of 458 cubic meters per hour and a length of up to 60 meters.

Fast and even delivery

The high speed of the whole machine ensures fast and uniform transportation, the material is not easy to be blocked, and it can be connected and fixed with other supporting equipment.

Sealed delivery

The sealed structure is conducive to conveying materials that are easy to fly, hot and strong odor, which can reduce the pollution to the environment and improve the working conditions of workers.

Easy to load and unload

Horizontal screw conveyors can be loaded and unloaded at any point on their conveying line, and vertical screw conveyors have superior feeding capacity compared to screw feeding devices.

Flexible layout

It can be arranged on elevated, ground or pit, can be installed horizontally or on a slope (≤15°), and can also be transported vertically upwards.

The following is the necessary information to provide to suppliers when specifying the appropriate auger conveyor for the job. Note that this section only outlines the main specifications, but more exist.

1. The capacity of the auger conveyor

Calculate the volume that needs to be conveyed per hour; this can be done by finding the required cubic feet per hour, selecting the recommended trough loading percentage for the conveyor, selecting the correct screw diameter, and determining the conveyor drive RPM. The recommended maximum auger conveyor capacity is usually given on a per screw diameter basis and is also affected by the pitch type and size as well as the material being conveyed.

2. Screw design and transmission

There are many screw designs, each with its own advantages. Certain types, such as paddle screws, are used to ensure additional mixing occurs, while short pitch screws are often used to incline the conveyor to maintain efficiency. Determine the helix design based on the desired functionality of the auger conveyor and choose from the available options. Also, screw design is drive dependent as there must be enough horsepower to pull material through the auger. Getting the correct driver for the desired screw shape will help ensure it works as intended.

3. Load type, trough load and trough design

What will go through the conveyor belt? Depending on the material, there are a variety of options available that will help make it easier to convey. For example, if the product is light, dry and hazardous, consider a sealed circular trough that provides high dust protection and regulates flow. Also, if the material is stagnant in nature, consider lower trough load percentages and shaftless screw types. The shape of the trough will affect the conveyor capacity, so determine which trough design is best for the desired flow rate.

4. Behavior, Control and Environment

Finally, consider the external factors and behavior of the screw conveyor in your application. How far must be covered? Will it increase/decrease in height, and will the material need to be separated from the operator/atmosphere? Also, is the conveyor running at a set speed, or is a variable speed drive used to vary the speed? Will the conveyor be part of a larger control system and will sensors need to be embedded for accuracy?

Application of Auger Conveyor

application of auger conveyor

Auger conveyor is divided into two types with shaft and without shaft. The shaft screw conveyor is suitable for non-sticky dry powder materials and small particle materials (such as: cement, fly ash, lime, grain, etc.), and the shaftless screw conveyor is suitable for conveying viscous and viscous materials. Risk of clogging on the shaft (eg: sludge, pulp, biomass, garbage, etc.), the use of fully enclosed conveying and easy-to-clean helical surfaces guarantees a hygienic environment and ensures that the delivered material is free from contamination and leaks. The following are its typical applications:

1. Agriculture

Auger conveyors are used in agriculture to move grain from a truck, grain cart or grain trailer into a grain storage bin (which is subsequently removed through a gravity chute at the bottom).

2. Grain processing

The main industry where the Auger conveyor is applied is the grain industry, because ordinary conveyor belts cannot successfully transport powder and granular objects, and such a result greatly affects the transportation and transmission operations of the grain industry, so the development of a spiral blade as a power transmission method The advanced screw conveyor can not only successfully convey the objects in the grain industry, but also save a lot of labor.

3. Waste treatment

Screw conveyors can also be found in wastewater treatment plants to remove solid waste from the treatment process.
