The Stainless Steel Screw Conveyor is made of 304/316L stainless steel, resistant to high temperature of 200°C, resistant to acid and alkali corrosion, not easy to rust, and conforms to food and medical hygiene standards.
Delivery capacity: 9-134.2t/h
Conveying distance: 2-70 meters
Conveying angle: horizontal, inclined, vertical
Because Stainless Steel Screw Conveyor is polished with 304 or 316 stainless steel, it is clean and hygienic, will not rust, and the equipment has good sealing performance, which can avoid pollution to the conveyed materials and the environment. It has good wear and corrosion resistance and can convey 200 ℃ powder, granules and small block materials. In addition, the Stainless Steel Screw Conveyor has a discharge valve at the lower end of the feed port, and the screw can be reversed for discharge, so it is very convenient for discharge and cleaning. It is suitable for horizontal or inclined conveying of powdery, granular and small block materials. Application In the fields of food, medicine and sewage sludge treatment.
The Stainless Steel Screw Conveyor strictly avoids any contamination of the processed material and applications that require absolute cleanliness and perfect corrosion resistance, such as environmental technology, flour and animal feed grinding, food processing and packaging, plastics and chemicals pharmaceutical industry and sewage sewage Mud processing and other industries.
The material of Stainless Steel Screw Conveyor can be divided into 304 and 316L stainless steel.
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: It is a material with lower carbon content in the same series of materials. Compared with 304, 316L stainless steel has stronger chemical corrosion resistance, and is more resistant to high temperature creep, stress rupture and tensile strength than other steel types. When applied When the scene has high requirements for corrosion and heat resistance, 316 stainless steel is better.
| 304 and 316 stainless steel comparison | ||||
| Serial number comparison item | Comparison item | 304 | 316L① | 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（m³/h） | Carbon content% | <0.08 | 0.03 | The higher the carbon content, the harder the city; the lower the carbon 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 |

1. Clean and hygienic, not easy to rust: all parts of the whole machine that are in contact with materials are made of stainless steel and polished internally and externally. The distance between the inner wall of the stainless steel feeding pipe and the spiral blade is not more than 3mm. The spiral blade is laser cut and processed, and all welding joints are polished to achieve smoothness. No material remains.
2. Corrosion resistance: It is made of 304 or 316 stainless steel, so it can avoid chemical reaction with acid and alkaline materials when conveying materials.
3. High temperature resistance: It can transport powder, granules and small lump materials with a temperature up to 200 ℃.
4. No pollution: The equipment has good sealing performance, which can avoid dust flying and material leakage during the transportation process.
5. There is a material cleaning port at the bottom. If you need to change the material, you only need to blow it down with an air gun to remove a small part of the residual material. And a safety switch is designed at the material cleaning port. Once the material cleaning door is opened, the power will be cut off, which is safe and reliable.
6. The heat insulation and dustproof design of imported universal bearings is adopted, and imported oil seals are designed and installed at both ends of the feeding machine to ensure that dust and sundries enter the bearings and have a long service life.
7. The circuit is designed for overload protection, which effectively protects the motor from burning out and is durable. It has the function of stopping when the material is full and automatic pumping when the material is not available. Just set the time of material consumption, no need for workers to look after.
The Stainless Steel Screw Conveyor uses the power of the motor to drive the screw shaft, and the screw blades push the material to be conveyed, and the force driven by the motor is greater than that of the material itself and the friction of the material on the screw conveyor casing, so that the material reaches The effect of moving forward, so as to achieve the conveying of materials.
The structure of the Stainless Steel Screw Conveyor is mainly composed of the driving device, the discharge port, the screw shaft, the intermediate suspension bearing, the shell and the feed port, etc. Usually, the screw shaft is equipped with a stopper at the end of the material movement direction (that is, the discharge port). Push the bearing to bear the axial reaction force of the material to the screw blade. When the fuselage is long, the middle suspension bearing should be added.
Dahan Stainless Steel Screw Conveyor Manufacturers produces 304 Stainless Steel Screw Conveyor, 316L Stainless Steel Screw Conveyor, Horizontal Stainless Steel Screw Conveyor, Inclined Stainless Steel Screw Conveyor, Vertical Stainless Steel Screw Conveyor, Large Stainless Steel Screw Conveyor, Small Stainless Steel Convey Steel, Belt Hopper Stainless Steel Screw Conveyor and other equipment, complete models, factory direct sales, the price as low as $500.
1. Material selection: materials can be divided into different types of stainless steel materials such as 304, 304L, 310, 316, 316L, etc., which can be reasonably selected according to the conveying materials. High-grade stainless steel materials are selected for high-corrosion materials, such as 316, 316L stainless steel materials, If the simple humidity is relatively high and the corrosion is weak, you can choose 304 stainless steel.
2. Workmanship standard: Since Stainless Steel Screw Conveyor is mainly used in food, medicine and other industries that require high sanitary conditions, the machine needs to be strictly polished to make the equipment easy to clean and disinfect during later use.
3. Sealing requirements: The seal between the screw shaft and the bearing adopts double-channel oil seal. One oil seal on the left prevents fine powder from entering the bearing seat, and one seal on the right prevents the lubricating grease of the bearing from flowing into the barrel along the shaft and polluting the material.
4. Others: such as whether it needs to be lengthened, the inclination angle of conveying, whether a hopper needs to be installed at the feed port, the size of the feed hopper, etc., Dahan manufacturers require customization.
