Next, let us understand the design and selection of the chain of the scraper conveyor together with the chain scraper conveyor.
According to the conveying capacity and material characteristics, select the appropriate chain speed to make the scraper chain run under reasonable load conditions. For common materials, the speed range of the scraper chain is generally 0.16 ～ 0.5m / s. The selection of specific speed can refer to the national standard GB10596.1-89 standard and the actual use experience of units in the same industry.
The scraper chain is composed of a basic chain link that plays a traction role and a scraper chain link that completes the scraping operation. Therefore, when selecting a chain, both the minimum tensile strength of the basic chain link and the connection strength of the joint between the scraper and the basic chain link must be considered.
According to the standard JB / T9154-1999 "Fork chain, scraper and sprocket for buried scraper conveyor", the tensile strength and the pitch of the scraper chain can only be selected within a certain range.
