MILL ANYWAYS

The bread baked in the village oven, needs no advertising: all articles del. Only here to store sacks of flour troublesome, much easier — the grain. And therefore, it is necessary to be able to grind grain at home without having to travel to mill. And get the flour as fine and coarse. At home in the village often have to roughing of grain, sunflower, tear down and to grind chalk, salt, various grain waste. And prepare feed on his farmstead — the dream of a villager: livestock and poultry in private households is increasing day by day.

Here’s a mechanism I built, and called it a peeling mill-mill. The main working part is the rotor and the stator. They serve as millstones — the first rotates inside the second. Anyway, my mill looks like. On a wooden stool is a motor power of 1 kW on 220 V, single phase, three phase rewound from discarded. To him with corners mounted the mill to the bearing in the Central hole of bearing down on the motor shaft: this shaft will rotate the rotor, delivering up to 3000 rpm.

 

The body of the mill is very similar to the round candy boxes with a thickness of 56 mm. and Ø348 the bottom of the box with the Board 50 mm — stator and cover (height 15 mm) covers “inside”. On top of the casing with screws M4 has a small pot with carved bottom. Instead of the last-adjusted damper-plate. The bottom — sleeve duster made of canvas (on the same screws). Under the flap and above the anther in the stator is made of Windows “entry and exit” — 15X30 mm. Through the top when the valve is open, the pot goes from “raw” and poured through the bottom of the finished “products”. Sleeve recommended use required: grinding will not scatter, and rush Directly into prepared bag or other container.

Stator — metal strip thickness 2 and a width of 54 mm. Curved it in a circle. Put into shape and filled from the one end of the aluminium — turned Cup with a 4 mm bottom. Then cut the corners 20X20X50 mm. Welded them to the side of the Cup from the inside, leaving free space for Windows, the surface was ribbed. (Then I thought that the parts can be just put on the screws — the effect is the same.) In the center of the stator drilled a hole for the shaft.

A blank for the rotor — Ø322 mm circle is cut from a metal sheet thickness of 3 mm. Then spent it on the circle Ø300 mm and broke it into 32 equal pieces. The cue points drilled hole Ø3 mm To them outside radius, made the cuts with a hacksaw and bent back petals, as shown in the drawing. In the center of the rotor wail sleeve length 45 mm and Ø28X5 mm.

The Assembly structure first put on the shaft the stator, then the key rotor and finally secured all pin through the bushing and shaft. The lid was fixed on top of four screws M6 in the circumference of the housing.

When the mill is required to comply with this order fill in, say, grain pot and start the engine. When he picks up the pace, open the top valve — fill of the grain. Add to it the number as soon as you remove the flour, working the lower valve. Try not to pour too: this can quickly adjust. However, you have to be attentive all the time — because the performance of the mill almost 5 kg/min. As shown, the quality of flour depends on the number of revolutions of the engine and, of course, by the clearance between the rotor and the stator. In my design for Stripping or disruption of the grain — a gap of 5 mm. For flour, you must reduce it to 2 mm: it is necessary to have a replacement rotor with a large diameter. But there is another way to change the wiring to the motor: to remove the mill from the motor shaft and putting separately, to establish the belt drive with interchangeable pulleys, increasing (flour) rpm.
