casting pin rail is generally made of ZG30SiMn material, this material has good mechanical properties and processing performance, suitable for the manufacture of parts subject to large loads and wear.

Mining casting scraper is made through the casting process of scraper, usually choose good steel as raw materials, with high hardness, high load bearing, good abrasion resistance and other characteristics. Mining casting scraper plays a key role in the scraper conveyor, through the chain pulling, moving in the central trough, driving coal or ore and other media to achieve continuous transport.

Material: the small pulley of crusher is usually made of cast iron materials, which have high strength and wear resistance and can withstand the impact and vibration generated in the crushing process. Structural design: The structural design of the small pulley is usually determined according to the specific model of the crusher and transmission requirements. It may include hub, spokes and rim, etc. The rim has grooves machined to match the belt for installing and fixing the belt.
