are emitted from the conveying system. Steel bars that are perpendicular to the conveyor chain, called flights, span across the width of the conveyor and move the coal aggregate to the rear of the machine. A urethane coated flight bar has reduced the overall sound levels by 5-7 dB(A) in a laboratory setting [4].

Coal Impumelelo coal mine Conveyor Dynamics, Inc.
At peak tonnage, the conveyor transports 2.4 kt/h (2,600 stph) of coal at a maximum speed of 6.5 m/s (21 ft/ sec). However, operators can reduce the conveyor speed to save power when they transport less tonnage. The motors are able to start the fully loaded belt at the lowest ambient temperature recorded for this location: -5oC (23oF).

Design, Analysis and Optimization of Drag Chain Conveyor
the chain links have obvious flights or paddles attached. In a drag conveyor, the chain moves the material directly, while a flight conveyor uses a series of wood, metal, or plastic flights attached to the chain at regular intervals, which push the material along the trough. The standard drag conveyor, or simply the drag chain

Conveyor belt Wikipedia
History. Primitive conveyor belts have been in use since the 19th century. In 1892, Thomas Robins began a series of inventions which led to the development of a conveyor belt used for carrying coal, ores and other products. In 1901, TON invented and started the production of steel conveyor belts. In 1905, Richard Sutcliffe invented the first conveyor belts for use in coal mines which
