Mill (factory)

“ Material that might economically be used in the workshop is indiscriminately passed out with the rubbish and sold away at a cheap rate — at a fraction of its real value. Tons of metal — good solid iron, often of the highest quality — which might be used for forging and stamping, are rejected and scrapped because it would take a trifle longer to handle. Other large scrap material might be slabbed and used without sending it to the mill, and thus large profits would accrue to the shed ”

“ The factory includes a water-power plant delivering, through an American water wheel and by cable, 250 horse-power to the main shafting, an auxiliary steam plant of 150 horse-power as a reserve, a rubber mill, a coffee mill, three sisal-stripping machines, smoke-houses, drying fields and houses for sisal, drying floors and houses for coffee, sorting rooms, blacksmith shop, machine shop, brass-fitting foundry, packing houses, warehouses, and other equipment. ”

“ If it were a shoe factory, we should need to add lasters, welters, sewers of uppers, etc., in a certain proportionate way, in order that one part of the mill might not get ahead of another and pile up unfinished products faster than they could be taken and completed. ”

“ Most of us today, when we think of power, think of electricity, gas, or steam, but it is very simple to consider the water in an ordinary little stream and the amount of power it can deliver.
Although the machinery built by the early millwrights was a bit crude, nevertheless it was functional and worked with efficient success.
On a recent scouting trip George and I took through Massachusetts, New Hampshire and Connecticut, we visited a few restored mills. One of them was in Rowley, Massachusetts, just off the Main Road, called the “Jewel Mill”. ”

“ Some mines cannot be economically operated without the treatment of the ores upon, or close to, the mining property. With certain sorts of low-grade ore, or with those kinds of ores that may be concentrated before shipment, provision should be early made for the erection of appropriately designed mills. We say the subject should be considered early, but we do not advocate the premature erection of any mill. ”

“ The mills have the air of being pit-head workings dealing with a cleaner material than coal. About them are lengthy conveyors, built up on high trestle timbers, that carry the logs from the water to the mill and from the mill to the dumps, that one instantly compares to the conveyors and winding gear of a coal mine. ”

“ There is one point which is of much interest to mill owners who wish to change their mills over to the gradual reduction process, that is, how far they can utilize their present plan of milling machinery in making the change. Of course the cleaning machinery is the same In both cases, so are the elevators, conveyors, bolting chests, etc. But to use the millstone is a debatable question. After carefully considering the matter I have come to the conclusion that it has its place, and an important one at that, under the new regime, viz., that of reducing the finer purified middlings to flour. ”

“ The model mill of the State, and of the world, for the reduction of silver ore, is the new 60-stamp mill of the Consolidated Virginia Mining Company. In this mill is to be found all that is valuable in any mill, and much in the way of machinery that can be seen in no other works of the kind. ”

“ So much is this the case that in one of our largest mills it is deemed preferable to move the middlings from one end of the mill to the other by means of a hopper bin on a car which runs on a track spiked to the floor, rather than to employ a conveyor. A mill built as I am going to describe would require from fifty to sixty horse-power to run it, and including steam power and building would cost from $10,000 to $12,000, according to location. ”

“ Since air flows through with the grain the flour is not heated very much. This type of mill is small, very fast, intermediate in price between steel mills and stone mill, lasts a long time, but when grinding, sounds like a Boeing 747 about to take off. ”

“ Nine-tenths, or perhaps ninety-nine hundredths, of all the flour consumed in Great Britain is made in roller mills, that is, mills in which the wheat is broken and floured by means of rollers, some grooved in varying degrees of fineness, some smooth, their work being preceded Roller milling. and supplemented by a wide range of other machinery. All roller mills worthy of the name are completely automatic, that is to say, from the time the raw material enters the mill warehouse till it is sacked, either in the shape of finished flour or of offals, it is touched by no human hand. ”

“ The richest portion is carried at once to the crushing mill, the poorer is thrown into another shed below, to be broken up and further picked, and the mere stones are wheeled off to the rubbish heap. The ore being broken small is thrown into the crushing mill, and passed once or twice through it, being returned to the mill by an endless chain of iron buckets, which dip into the heap of crushed ore below, and, carrying it up, empty themselves into the mill. ”

“ It is only a matter of short time when our milling inventors will design machinery especially for small mills; in fact they are now doing it, and every day brings it more within the power of the small miller to improve his manner of milling. To show what can be done in this direction I will briefly describe a mill of about ninety barrels maximum capacity per twenty-four hours, which is as small as can be profitably worked. ”

“ We are so absorbed in the tumult of mass output that we scarcely realize the part played by the old mills in rearing the cornerstone of our vast industrial activity. The phrase, “horse power,” now geared to myriad millions of units, in all likelihood, began with the horse-operated grist mill. A horse provided the power. The creaking water wheels with their rhythmic splash, were the outposts of the hydroelectric age which has harnessed rivers and falls and wrought marvels of production the world over. ”

“ There seems to be a strange diversity of opinion as to the extent of the participation of machinery manufacturers in the financing of the mills. A mill man of Anderson, South Carolina, said that the machinery people have played a larger part than the commission houses in the establishment of Southern mills; that the machinery business was at a standstill in New England at the time of the great activity in mill building in the Southern States, and the machinery manufacturers began to look about for mills to equip. ”

“ It is a grewsome place. The machinery reminds one of the pictures that we have all seen of some of the contrivances they used to have in the days of the Inquisition with which to torture people, and it is hard to keep back a shudder as one looks at this work. Sometimes there is as much as a ton of powder at one time in the big hopper of this machine. In one of these mills at the Du Pont Works you will notice that the stone wall is eight feet thick on one side. This is on the side next to a press-mill. [Pg 778] One side of the place is entirely of wood. ”

“ Even in the iron industry where could a line be drawn-at the end of mining the ore, the production of the pig-iron or steel ingots, when the rolling mill operation is completed, fabrication on order or at some stage of manufacture into standard merchandise? ”

“ It is not a snobbish rich-man's college, devoted to leisurely nonsense. It is the property of the people of the state, and what they want—or what they are told they want—is a mill to turn out men and women who will lead moral lives, play bridge, drive good cars, be enterprising in business, and occasionally mention books, though they are not expected to have time to read them. It is a Ford Motor Factory, and if its products rattle a little, they are beautifully standardized, with perfectly interchangeable parts. ”

“ Everyone likes to play in the water, so we went to work about August 1, 1960. You can well imagine the condition of the mill. Windows were shattered, the sills were powder, the roof practically gone, and the building had a definite cant to the east’ard. It really looked hopeless.
Fortunately, most of the ancient machinery—the stones, gears, brakes, and chutes—were still intact, even the miller’s little desk where he kept his records, and the ancient bin for storage.
The beams, the corner post studs, etc. are of tremendous size and all mortised, tenoned and dowelled, and hard as rock. ”

“ This requires a mill with movable rolls able to continually tighten the gap as slabs grow thinner. Although reversing mills have lower production rates and are more complicated than regular rolling mills, they are more versatile and require fewer machines. ”

“ The American mills being devoted to a large variety of operations, instead of being confined to a single process after the manner of those of European type, require a great deal more care in their organization, not merely in the original lay-out for the purpose of arranging for the passage of the stock in processes from the raw material to the finished product in as straight lines as possible, but due consideration should also be given to providing facilities for the enlargement of the mill. ”

“ Everything has become venal, and competition invades even the domain of thought.
"The factory crushing the workshop; the showy establishment absorbing the humble shop; the artisan who is his own master replaced by the day-laborer; cultivation by the plow superseding that by the spade, and bringing the poor man's field under disgraceful homage to the money-lender; bankruptcies multiplied; manufacturing industry transformed by the ill-regulated extension of credit into a system of gambling where no one, not even the rogue, can be sure of winning ”

“ Upon the Rand, South Africa, a territory dominated by Englishmen, every mine is equipped with its own mill, and all notions of mining cover the inseparable idea of local ore treatment. Here, in our country, there are many, many mines which have absolutely no means of treating their own products and the managers give no thought whatever to metallurgical or milling lines. There are, on the other hand, many companies that have erected private plants at their mines for the extraction of metallic contents from the ores. ”

“ The common paper mill being limited by its number of vats, no advantage can be taken of the frequent accessions of power which generally happen in the course of the year, but, on the contrary, as scarcely any mills are capable of preparing stuff for twelve vats, every accession of power to the mill, where a machine is employed, will increase its produce without any additional expense. ”

“ In all the world there is no other wizard that could have formed it, no other smith that could have welded its parts together or forged its lid of many colors. You have only to whisper your wishes into the small orifice on the top of the mill, and it will begin to run—you can hear its wheels buzzing and its levers creaking. Lay it on this side and it will grind flour—flour for your kitchen, flour for your neighbors, flour for the market. Turn the mill over, thus, and it will grind salt—salt for seasoning, salt for the reindeer, salt for everything. ”

“ The mill, which has a larger capacity than any other in the State, has been continuously operated since March, 1882, under the same management, and the highest standard of efficiency has been maintained throughout by the introduction of the latest type of machinery, to keep pace with modern inventions. ”

“ The entire mill, thus, is about as simple a machine as one could devise. The moving parts are few and could be called primitively clumsy in comparison to some of the sleek masterpieces of modern industrial design. The miller can make only three operating adjustments: in the sail area presented to the wind, in the rate of grain fed to the stones, and in the distance between the stones. He has no control over wind speed, cannot shift the gear ratio of the mill—or even shift the stones out of gear—and, finally, cannot determine his own hours of work and rest. ”

“ A faint streak of light was apparent through a crack in the boards.
"That must be where their workroom is," Frank whispered.
The sound of machinery in motion continued.
"We've struck them at the right time," said Joe, in a low voice. "They must do their work at night."
"We've got to make sure."
"How can we get inside the mill?"
"The willow tree. We'll have to climb it and drop down on the roof."
"What if they hear us? We won't have a chance to get away."
"They won't hear us," said Frank confidently. "The walls are of stone. Anyway, the sound of machinery will drown out any noises from outside. ”

“ One man runs each of these mills. He cannot start the machinery in motion and go away, like the man who has charge of a rolling-mill, but he must stay in the place all the time, and feed the stones to the machinery that crushes them into grains of various sizes. He shovels the powder into a large hopper, big wooden wheels go around and around, and the powder passes between zinc rolls and through sieves of various sizes. ”

“ Whenever inspectors or scientific curiosity seekers visit his mill his mute workmen assume the air of being very busy, the cars laden with his so-called ‘ore’ rumble out of the tunnel, and their contents are ostentatiously poured into the furnace, or appear to be poured into it, really dropping into a receptacle beneath, to be carried back into the mine again. ”

“ Aaron, therefore, might choose between seeking a market outside for his pig iron or building a mill to work it. To build a mill would require, first, a large outlay of capital, then an organization of expert workers and superintendents, and thirdly a market for his wrought iron in competition with the product of the established mill, now Enoch’s. ”
