Here is a separator the proper combination of sieve surface, pitch and air separation to handle a large stream of grain and do excellent t work. A level feed gate, controlled by balance weights, regulates the flow of grain and supplies an even stream, across the entire width of the shaking shoe. Has ample sieve surface for handling easily the specific capacities. Built high enough to provide for the right pitch and yet heavy enough to sustain rigidly the entire weight. Standing on two foundations beams, the floor is easily kept clean. Two aspirations are given the grain - one at the beginning and the other at the end of the process. This is accomplished in numbers 0, 1, 2, and 3 by a large, slow speed fan located in the exact place where an even, regular current of air envelops each berry. In numbers 4 to 14, two fans are used. The peculiar movement imparted to the grain by the air current loosens and removed much of the dust and impurities, thus tending to keep the mill clean and prevent dust explosion. The shaking shoe scalps off the roughage; the second sieve the smaller sticks, wild oats, king head, etc. while the third removes the fine seeds, sands, etc. Extra sieves for corn, oats, barley, etc.
