The Mechanical Handling and Storing of Material

36o THE MECHANICAL HANDLING OF MATERIAL call for. The ore trough is essential for two considerations; firstly, in the event of its being desired to speedily discharge a vessel, as the shorter the distance the ore is moved the more quickly this will be accomplished; secondly, the stock pile should at all times be accessible to the transporter which takes the ore to feed the furnaces. All ore taken from the vessel’s hold, except such as is immediately dropped into trucks for carriage to more distant points, is unloaded into the trough at the rear of the unloaders, and thence is distributed by the 10-ton grabs into the stock yard or directly into the pockets situated near the furnace. Thus the fifteen 5-ton grabs can be constantly at work removing the ore from vessels, whilst the 10-ton grabs can either be feeding the furnaces from the stock pile or removing the ore from the trough to the stock piles.1 1 The Author is indebted to the Iron 1'rade Review, of Cleveland, Ohio, and to the Iron Age, of New York, for the above description.
