1. You should select the appropriate chain speed according to capacity and material properties, so that make the scraper chain run under reasonable load conditions. For the common material, scraper chain operating speed range is generally 0.16 ~ 0.5m / s. You can choose a specific speed reference GB GB10596.1-89 standards and practical experience in the same industry units.
2. You should select the appropriate structure of scraper chain on the basis of delivery materials and transporting form. The selection principles are as following: in general, preferred forging chain, greater hardness of dust-like material should not be used bush roller chain, chain prone to floating material might as well use bush roller chain and double-plate chain. To ensure maximize the carrying capacity of scraper chain and avoid waste of energy and materials, you should be guaranteed under the condition that the scraper chain can bearing the maximum working load, choose the scraper chain closest to the required load and the maximum working load.
3. Select the chain of materials Scraper chain material must ensure a certain strength. In the long time work, insufficient rigidity will force the scraper chain produce plastically deformed scraper chain elongation, and chain in installation has been tensioned, allowed elongated room is little. This will make scraper conveyor bear a powerful additional load, which will inevitably bring damage to the chain. In other words, scraper chain stiffness shortage will make scraper chain obvious distortion in use. The ideal steel material is manufacturing performance not less than 45, scraper chain have to overcome a lot of friction, bearing a lot of dynamic load and static load, so after the scraper chain manufacturing and post-weld, it should be carried out heat treatment, make it has high strength, toughness and wear resistance characteristic.
