Release Time：2021-03-01
The selection of scraper conveyor chain is very important, because the buried scraper conveyor is a kind of conveying equipment that continuously conveys bulk materials in a rectangular closed section shell with the help of a moving scraper chain. Its core component is scraper chain. In grain and oil processing plants, the chains commonly used in scraper conveyor are die forging chain, bending plate chain and welding bending plate chain.

Each section of the sleeve roller chain structure has two chain plates, two pin shafts, two independent sleeves (the sleeves are not connected to the chain plates) and four snap rings. Sometimes bushings are not required, and the inner and outer link plates are stamped. The sleeve roller chain is characterized by wear resistance, high precision and fatigue resistance. It is suitable for the working environment with frequent starting and large impact load, and is suitable for the buried scraper conveyor below 500 t/h in the transportation department. Existing problems: heavy, commonly used in heavy-duty transportation, used for cleaning materials with slightly larger particles in the grain and oil industry, and the scope of application is narrow. The equipment for the production chain of general enterprises is not in place, and the processing technology level after stamping is insufficient, which is easy to cause the chain to break and wear, which seriously affects the service life of the chain.
Scraper conveyor chain application recommend:
1. Under normal circumstances, die forging chain is suitable for light scraper in small and medium-sized grain, oil and food processing plants in China.
2. For the curved roller chain: dust, soybean powder, bran and small particles in the grain conveying process are easy to adhere to the roller, which seriously affects the life of the roller, resulting in shortened life of the curved roller chain, thereby increasing production costs and causing safety Hidden dangers. Therefore, the chain is suitable for transporting cleaner materials with weak accessory capabilities.
3. Welded curved chain: high strength, wear resistance, strong resistance to harsh transportation environment, suitable for large output and all-weather transportation of various materials, as well as the transportation of viscous materials such as dust and soybean meal.
Lightscraper conveyorDie forging/welding bending chain can be selected, bending roller chain/welding bending plate can be selected for cleaning materials with weak adhesion, and bending roller chain/welding bending plate can be selected for wet scraper conveyor or welding bending plate chain and other poor working environment of scraper conveyor. Welded curved plate chain has the advantages of anti-fatigue, high strength and long life, and is the main choice in the field of grain transportation.
