set of 16-inch burr stones, and an elevator. We grind all kinds of feed,
also corn meal and Graham flour. We have ground 8,340 bushels, and would have ground much more if corn had not been a very poor crop here for the past two seasons; besides, we have our farm to attend to, and cannot keep it running all the time that we have wind. We have not run a full day at any time, but have ground 125 bushels in a day. When the burr is in good shape we can grind 20 bushels an hour, and shell at the same time in the average winds that we have. The mill has withstood storms without number, even one that blew down a house near it, and another that blew down many smaller mills. It is one of the best investments any one can make." The writer saw this mill about sixty days ago, and it is in good shape, and doing the work as stated. The only repairs that it has required during four years was one bevel pinion put on this spring. The owner of a 16-foot diameter mill, erected at Blue Springs. Neb., says that "with a fair wind it grinds easily 15 bushels of corn per hour with a No. 3 grinder, also runs a corn-sheller and pump at the same time, and that it works smoothly and is entirely self-regulating." The No. 3 grinder referred to has chilled iron burrs, and requires from 3 to 4 horse-power to grind 15 bushels of corn per hour. Of one of these 16-foot mills that has been running since 1875 in Northern Illinois, the owner writes: "In windy days I saw cord-wood as fast as the wood can be handled, doing more work than I used to accomplish with five horses." The owner of one of these mills, 20 feet in diameter, running in the southwestern part of this State, writes that he has a corn-sheller and two iron grinding mills with 8-inch burrs attached to it; also a bolting |
