Stainless Steel Auger Conveyor

Working Principle of Stainless Steel Auger Conveyor

Stainless steel auger conveyor conveys the material along the displacement direction by the rotating spiral blade, which relies on the double force of the material's own gravity and the friction force of the screw conveyor casing on the material; and the displacement of the material in the middle bearing depends on The rear material is conveyed by the thrust of forward movement; the screw conveyor is equipped with a feed inlet and a driving device (reducer, motor) at one end, and a discharge port at the other end. When the machine is operating, the spiral blade pushes the material to move. In this movement, the weight of the material itself will friction with the groove wall to generate force, which will cause the material to move forward along the direction of the spiral blade grinding along with the rotation of the screw. For the spiral conveyor with a large inclination angle, the material is continuously poured into the pipe wall and blades, and the centrifugal force on the material is greater than its own gravity, and then it is pushed forward.

Structure of Stainless Steel Auger Conveyor

1. Feeding device: welded with angle steel and steel plate, connected with feeding equipment, at the upper part of the tail.

2. Head section: It is mainly composed of three parts: thrust bearing, spiral body, and casing. The thrust bearing is to bear the axial thrust when the material is conveyed. When using a helical gear reducer, the additional overhung load of the drive must also be taken at the same time.

3. Intermediate section: It mainly includes the hanging bearing, the spiral body and the casing. The hanging bearing supports the screw shaft, so that the stainless steel screw conveyor can work normally, which is an important part.

4. Driving device: It is composed of motor, reducer, coupling and other parts, and is the main component for the stable operation of the equipment.

6. Tail section: mainly consists of four parts: flat bearing, screw body, suspension bearing, and casing. The flat bearing can not only support the tail screw, but also be used to adjust the slight change in the axial length of the entire screw conveyor during installation.

Material Description of Stainless Steel Auger Conveyor

304 and 316 stainless steel comparison
Serial number comparison item	Comparison item	304	316L	Remark
1	Price	Low	High	304 stainless steel has excellent performance, low unit price, and is more widely used
2	Molybdenum content%	0	2-3	The higher the Mo content, the better the corrosion resistance and heat resistance
3	Nickel content%	8-10.5	10-14	The higher the Ni content, the better the corrosion resistance and heat resistance
4	Carbon content%	<0.08	0.03	The higher the C content, the lower the C content, the better the welding performance
Note	1: When we refer to 316 stainless steel, it refers to 316L stainless steel 2: Carbon is a strong austenite forming element, which can significantly increase the strength of steel, but the higher the carbon content in carbon steel, the worse the plasticity, and carbon also has an adverse effect on corrosion resistance

S tainless steel screw conveyor materials can be divided into 304, 316L two stainless steel materials.

The difference between 304 stainless steel and 316L stainless steel:

304 stainless steel can withstand high temperature of 800 ℃, has the characteristics of corrosion resistance, easy processing, and good toughness. When the requirements for corrosion resistance are not high, 304 stainless steel is better because the unit price of 304 stainless steel is lower than that of 316 stainless steel.

316L stainless steel is a material with a lower carbon content in the same series. Compared with 304, 316L stainless steel has stronger chemical corrosion resistance, and is more resistant to high temperature creep, stress fracture and tensile strength than other steels. When there are higher requirements for corrosion and heat resistance, 316 stainless steel is better.
