stainless screw conveyor is a kind of equipment used for material transfer in industrial production. Its price range varies significantly, usually ranging from US$100 to US$5,000, and the specific cost is affected by many factors. These factors include the specific type of equipment (such as U-shaped or tubular, with or without shaft structure), the grade of stainless steel material selected (such as 304 or 316L), the physical size of the equipment (such as screw diameter and conveying length), the required processing capacity, and the configuration of supporting components (such as motors, reducers, seals, etc.). In current industrial applications, the actual requirements for equipment cleanliness and corrosion resistance are the key considerations in determining the cost of stainless steel screw conveyor.
What are the types of stainless steel screw conveyors?
Stainless steel screw conveyors can be divided into many types according to their structural form, working principle and application scenarios, and these types of differences directly constitute a significant difference in their basic prices.
U-shaped stainless steel screw conveyor
U-shaped screw conveyors use an open or covered U-shaped trough structure. This design is relatively intuitive, and the manufacturing process and sealing requirements are usually lower than those of fully enclosed pipelines. Under the same conveying capacity and material requirements, the price of U-type stainless screw conveyor is usually in a relatively low range. Its manufacturing cost is mainly reflected in the cutting, bending, welding of stainless steel plates and the processing of spiral blades.
Tubular stainless screw conveyor (round tube type)
The tubular screw conveyor adopts a fully enclosed round tube shell, and the material is transported in a closed pipe. This design provides better sealing and anti-pollution capabilities. Compared with the U-type, the price of tubular stainless screw conveyor is usually one level higher. Its manufacturing cost includes the rolling of round tubes, more precise welding technology, and sealing requirements for pipe body flanges and inlets and outlets. The fully enclosed environment also has stricter requirements on the selection of bearing seats and seals.
Shafted stainless screw conveyor
The spiral blades of the shafted screw conveyor are fixedly welded on the central tube shaft, and the materials are pushed by the rotation of the central shaft. This is the traditional screw conveyor design. This is a more common type of stainless screw conveyor with relatively controllable cost. Its price is mainly affected by the material, diameter and processing technology of the central shaft.
Shaftless Stainless Screw Conveyor
The shaftless screw conveyor does not have a central shaft. The spiral blade is a thick, flexible or rigid spiral body that rotates and pushes the material directly in the U-shaped groove or pipe groove. The price of the shaftless stainless screw conveyor is usually higher than that of the shafted type with the same conveying capacity. Its manufacturing cost mainly lies in the special processing of the shaftless spiral body, the installation of the liner inside the trough body (usually wear-resistant or ultra-high molecular polyethylene), and the special bearing support structure at the drive end.
What are the factors affecting the price of the stainless screw conveyor?
In addition to the above price differences by type, the following factors will also have a significant impact on the final quotation of the stainless screw conveyor.
Stainless steel material grade and surface treatment
Material grade: 304 stainless steel is the most commonly used stainless steel grade with good corrosion resistance and processing properties. 316L stainless steel contains molybdenum and has stronger resistance to chloride corrosion. It is preferred in seawater environments, some scenes with strong acidity and alkalinity, or scenes with higher corrosion protection requirements. Its cost is significantly higher than 304 stainless steel.
Surface treatment: In order to meet the requirements of cleanliness or aesthetics in specific industries, the surface of stainless steel will be treated. The cost of wire drawing is relatively low, while the mirror polishing effect requires precise grinding and polishing technology, which will greatly increase the processing cost. In the field of fine chemicals, it is usually required that the surface of the contact material is mirror polished to avoid material residue and bacterial growth.
Conveying capacity and size parameters
Spiral diameter: The spiral diameter is directly related to the amount of material that can be conveyed in a single rotation. The larger the diameter, the greater the amount of plate required, and the processing difficulty and transportation cost will increase accordingly.
Conveying length: The length of the equipment directly determines the material consumption of the main components such as the tank, spiral, and support frame. The longer the length, not only the material cost will increase, but also the transportation and installation costs will increase accordingly.
Motor power: The conveying capacity (flow), conveying distance, conveying angle and material characteristics (density, viscosity, abrasiveness) jointly determine the required motor power. The greater the power, the higher the cost of the motor and reducer.
In actual application, the purchase cost of the stainless screw conveyor reflects the investment in materials, processes and components involved in the manufacture of the equipment. To select a device suitable for specific production needs, it is necessary to comprehensively evaluate its structural characteristics, achievable conveying parameters and compatibility with existing production lines. The long-term operation and maintenance of the equipment, including the replacement of parts and daily cleaning, are also aspects that need to be considered during use.
