The document is an excerpt from the September/October 2010 issue of Grain & Feed Milling Technology magazine. It discusses a new Bolt 'n' Go chain and flight system for conveyor chains that allows flights to be changed inside the conveyor without removing tension from the chain. The system was first installed in 2006 and provides benefits like reduced maintenance costs and downtime compared to traditional systems. It has been successfully used on various grain and feed handling facilities.
