The chain material of the chain scraper conveyor is made of paraffin precision casting, and the material is 45 steel. The die-forged chain is forged and processed, and the material is 40Mn. The roller chain is stamped and formed.The chain of the chain scraper conveyor of China Coal Group is divided into scraper chain, die forging chain, cast steel chain, stamping chain, welding chain, and die forging easy dismantling chain. Users can choose appropriate varieties, materials and specifications according to different materials to be conveyed.
The chains of scraper chain conveyor have different classification standards, and there are different types under different classification standards. For example, according to the arrangement and structure of the chute, it can be divided into two types: side-by-side and overlapping. If it is divided according to the number of chains, it can be divided into four types: single chain, double chain, double center chain and triple chain. The commonly used models of scraper chain conveyor are MC type, MZ type and MS type.
The chain of the chain scraper conveyor should be in the state of pulling material when working. If it must be in the working state of pushing material, the length of the pushing part cannot be greater than the length of the conveyor, otherwise the shaft strength needs to be recalculated. In addition, the direction of chain movement should be indicated on the general map of the conveyor. The chain of the chain scraper conveyor is usually a high-strength circular chain that meets the C-level standard, with a safety factor of 9 or more, and can withstand a 30,000-word cyclic fatigue test. Under normal use, it is not easy to break.
