Sources Of Roller Mills

Stationary Roller-type Feed Mill

The roller-crushing action of the Sears mill minimizes dust waste. Two heavy-duty rollers {6 inches long, 9 inches in diameter) run on self-aligning ball bearings. This mill allows crimping or crushing of hard grain shells and makes feed more palatable than grain which is finely ground. It has a large 19 by 23i/rinch, 16-gauge steel hopper. The hopper height, 32 inches, facilitates loading. The mill is furnished with a motor mount bolted to a stand and a 16-inch V-belt pulley. The overall measurement is 22 by 34 by 32 inches high. Requiring a 214-inch motor pulley, this mill operates with a 4 h.p. gasoline engine or a ly2 h.p. electric motor for a capacity of 15 bushels of oats, 50 bushels of cracked corn, or 35 bushels of wheat per hour.

W-W Roller Mills

The W-W roller mill handles any type of small grain: shelled corn, oats, barley, sorghum grains, or wheat. It crimps, cracks, or crumbles, depending upon the degree of fineness desired. This mill has a heavy-duty construction, and the chilled, white-iron, 10-inch diameter rolls do not chip or peel and can be regrooved when necessary. A single control wheel handles all the adjustments. Roller sizes vary from 6 to 36 inches in diameter. Optional accessories are available.

Grain Rollers

Particularly of use in raising goats, cattle, and sheep, the Gaubert grain rollers come with two equal cylinders 300 millimeters in diameter and 130 millimeters in width. The grain-feeding mechanism is mounted in self-lubricating bronze rings powered by a 3 h.p. motor driving through a set of double pulleys and two V-belts, or through a one-flat, three-ply belt. Grains are rolled without crushing at a rate of 200 to 400 kilograms per hour, depending upon the grain.

Hammer Mills The hammer mill is most often used today to grind feed for livestock and poultry. Instead of having burrs for the grinding process, the hammer mill employs rows of free-swinging, steel flails whirling at high speeds with an action similar to that of a leaf shredder. The impact of these hammers reduces the particle size. The screen under the hammers controls the fineness of the ground feed; the finer the mesh, the finer the feed. Hammer mills will grind all kinds of feed, even mixed grains, ear corn, and hay.

Large units are generally driven by the power take-off shaft of a tractor. A unit which requires 20 h.p. to drive produces 10 to 20 hundredweight of ground material per hour. The smaller hammer mills are popular for farm production of animal feed and concentrate mixes, and they are usually operated by an electric motor. The actual capacity depends on the rate of feeding, the speed of the hammers, the amount of power available, the kind of material being ground, fineness of grind, size of screen mesh, and the size of the mill. The capacity of a hammer mill for a given fineness and horsepower

Hammer Mill Screen

A look inside a hammer mill.

is ultimately limited by the size of the grading screen.

The main advantages of a hammer mill are its simple construction and low replacement cost for spare parts, availability in a large range of sizes, durability of hammers combined with no reduction of efficiency during their lifetime, and there is little ciiance of damage from hard foreign objects like stones or from empty running of the machine. The main disadvantages are an initial high cost, high power requirements, inability to produce a uniform grind, and production of a high percentage of fines.

Though a hammer mill will not produce a uniform grind, some people feel that it produces a satisfactory flour if a fine enough screen is used during milling and the material is sifted afterwards. Hammer mills are used for a number of other functions besides grinding feed—primary seed cleaning, for example. The C. S. Bell Company has successfully used their hammer mill for such homestead tasks as processing garbage for compost, grinding wood and bark for mulch, and even shredding paper for worm-farm bedding.
