English: Identifier: factoryindustria35newy (find matches) Text Appearing After Image: With the view of treating ores which were not well suited to treatment by the pot-roast process Messrs. Dwight and Lloyd designed the machine shown on page 862. It consists of a revolving drum resting on rollers like a copper converter. This drum is caused to revolve slowly about its axis by the friction of the drive rollers. It acts as a conveyor of the ore as well as a roaster. Inside the drum there is a suction chamber which is connected with a suction fan. The moving rims form an air-tight joint with the edges of the stationary suction box which occupies the top quadrant of the circle inside the drum. The material to be sintered is fed in a thin layer upon the grated face of the drum from an overhead ore-hopper. Immediately the ore reaches the drum surface it comes in contact with the igniter. This is either a series of gasoline or gas jets, an oil flame, charcoal brazier, hot roasted ore, hot sinter, or anything capable of promoting the oxidation of the charge. The ignition medium acts downwards on the charge in such a way as to kindle the ore stream uniformly across the whole width of the conveyor. The roasting action started by the igniter is augmented and maintained by the steadily flowing airstreams that are sucked down through the ore layer by the suction fan as the ore drum slowly revolves across the suction box placed within the top quadrant of the drum. The ore liyei" 'is usuatly abdiil '4 inches m thickness and requires about 20 minutes for the, sintering action to be completed. The speed of the clrum fs' regulated in such a way as to enable the whole layer to te corhpletely sintered down by tlie time it reaches the far end of the suction box. The sintered ore is stripped from the drum and automaticallv discharsred bv the pointed grizzly. Note About Images |
