The material of the screw conveyor blades

As the core component of the screw conveyor, the screw conveyor blade is mainly divided into three materials: carbon steel, stainless steel and manganese steel. The materials and occasions of the screw conveyors of these three materials are different, so the user should choose different blade material, I will introduce you to:

Classification of screw conveyor blade materials

Screw conveyor blade - ordinary carbon steel material

For the carbon steel screw conveyor blades, the use is more common, suitable for general material transportation, its advantages and disadvantages are summarized as follows:

Advantages: 

1)Carbon steel screw conveyor blades have higher hardness and wear resistance, which can guarantee the long-term use.

2)Due to the low cost of carbon steel material, the price of the screw conveyor blades for carbon steel is lower.

Disadvantages: 

1)The hot hardness will be poor, because when the working temperature is greater than 200 ° C, its hardness and wear resistance will drop sharply.

2)For some corrosive, high-temperature materials, carbon steel screw conveyors are not competent.

Screw conveyor blades - stainless steel

Stainless steel spiral conveyor blades can transport acid, alkaline and high temperature materials. The advantages and disadvantages are summarized as follows:

Advantages: 

1)Acid and alkali resistance, high temperature resistance or low temperature resistance, wear resistance, longer service life.

2)It is not easy to rust, so it will not pollute the conveying materials, and the blade cleaning is simpler.

Disadvantages: The cost will be higher than carbon steel.

Screw conveyor blade - manganese steel material

The strength of the manganese steel screw conveyor blade will be higher, so its anti-wear performance will be better, suitable for conveying honing materials, its advantages and disadvantages are summarized as follows:

Advantages: high hardness and long service life.

Disadvantages: Manganese steel is not stainless steel, and it is easy to rust when not properly maintained.

Summary: The selection of the above three types of screw conveyor blades is mainly selected by the user's conveying materials. Carbon steel is suitable for the transportation of common materials. The stainless steel screw conveyor is more suitable for conveying corrosive materials, while manganese steel material. The blade has higher strength and is suitable for honing materials. The price cost of these three materials is: manganese steel <stainless steel < manganese steel.
