What is BS 4831 – Chain conveyors for mining about?
BS 4831 is a British standard that discusses the specification for shackle type connector units for chain conveyors for mining. The purpose of the conveyor system on a continuous miner or loading machine is to transport the coal from the base region to the material handling system behind the machine.
BS 4831 specifies the requirements for a range of shackle type connector units for use with chain conveyors. Each unit consists of the following components:
- Shackle type connector
- Connector bolt
- Connector nut
Note: This BS 4831 is not intended to indicate a complete design, but it gives sufficient detail to ensure dimensional compatibility with chains complying with ISO 610 and scraper bars complying with ISO 5612. The connector units specified are intended for use as part of 14, 18-, 22-, 24- and 26-mm diameter chain assemblies in which the connectors are fitted tightly onto scraper bars.
