Abstract
A chain conveyor for a miner in which the chain adjacent the drive sprocket is guided and supported by channels in a casting such that tension in the chain is reacted by the casting and separated from the driving force applied to the chain by the drive sprocket. The casting may be spring loaded away from the idler sprocket at the other end of the conveyor. The pitch of the sprocket teeth is preferably less than the pitch of the chain, allowing for drive sprocket build up from entrained fines.
