Auger Conveyor

Introduction of Auger Conveyor

Auger Conveyor is mainly used for conveying powder, granules and small block materials, and can convey materials horizontally, inclined or vertically. It is divided into shaft screw conveyor, shaftless screw conveyor, tubular screw conveyor, U-shaped screw conveyor, Stainless steel screw conveyors, etc., have a full range of equipment models, and the conveying capacity can reach 458 cubic meters per hour. They are commonly used in chemical, building materials, grain, food and other industries.

Auger Conveyor Application

Auger Conveyor can be used in food, building materials, metallurgy, coal, chemical, electric power and other industries to convey powder, granular or small lump materials, such as cement, concrete, mud, feed, chemical fertilizer, fly ash, coal, sawdust, starch , corn, wheat and other materials, it is not suitable to transport materials that are perishable, viscous, bulky and easy to agglomerate.

3. Good sealing, the shell is made of seamless steel pipe, and the ends are connected with each other by flanges, with good rigidity, which can be fully enclosed to prevent dust pollution, and can also be opened for transportation;

4. Reasonable design and long service life: the location of the inlet and outlet is flexible, and the discharge end is also equipped with a cleaning device, so the conveyor has a long service life;

5. During the conveying process, it can also complete the process of material mixing, stirring, cooling and so on.

How does the Auger Conveyor work?

When the material enters the casing of the Auger Conveyor, it does not rotate with the spiral body due to the gravity of the material and the frictional force on the casing. The material moves forward under the push of the rotating helical blade until it is discharged from the discharge port.

Auger Conveyor Structure and Details

An Auger Conveyor usually consists of three parts: the screw machine body, the entry and exit device, and the drive device.

Drive device: It consists of a motor and a reducer.

Spiral blade: It can be divided into several forms such as full blade type, blade type, paddle type, and tooth type.

Chassis: There are two types of "U"-shaped casing and "O" casing.

Screw shaft: hollow, made of steel pipe, high strength, light weight, easy to connect. Use a short length of solid shaft at the shaft-to-shaft connection and where you mount the bearings. Extend the solid shaft into the hollow shaft at the joint and use high-strength bolts to pass through the hollow shaft and the solid shaft in a mutually perpendicular direction to fix and connect the helical shaft.

Auger Conveyor Selection Key Points

1. Conveying materials

It mainly includes the wrong viscosity of the material, the water content, the acidity and alkalinity, and whether it can be broken. Different material properties require different Auger Conveyor models to be selected. In terms of different spiral blade forms, full-surface blades should be used when conveying materials with good scattering properties such as wheat and rice; belt-type blades should be used when conveying oily materials with high viscosity and easy bonding to prevent clogging . At the same time, if the raw grain is to be transported and does not need to be broken, Auger Conveyor is generally not used. In terms of design with or without a central shaft, environmental-friendly enterprises are involved in the transportation and measurement of foggy sewage, sludge, and domestic waste. Such materials are viscous and entangled to a certain extent, so they need to adopt a design without a central shaft to prevent materials from sticking to the surface. on the spiral blade.

2. Delivery capacity

Common screw diameters are 100mm, 200mm, 250mm, 315mm, 400mm, 500mm, 600mm, etc. The larger the diameter, the greater the conveying capacity, which can be selected or customized according to the specific conveying capacity.

3. Conveying speed

The conveying speed of the Auger Conveyor should not be too high, otherwise it will have a greater impact on the screw blades, resulting in increased wear on the blades and U-shaped grooves, affecting the service life and metering efficiency of the feeder.

4. Use the on-site environment

The use site of Auger Conveyor determines the length, inclination angle and model of the equipment. For different lengths and inclination angles, the required power, blade thickness and pipe wall thickness of the screw feeder will be different.
