Milling roller

for M e h r f a G h w a 1 ζ e η s t u h 1

The purpose of the invention is · # © to make the roller mill, as today's main grinding machine in the milling industry, suitable for the simultaneous processing of several passages. As is well known, the ground material is passed several times over a grinding machine before it leaves the mill in the finished products. ”The structure of relatively coarse parts is constantly changing into finer ¹ I

In order to be able to process all passages, called passages, simultaneously and thus continuously, a separate grinding machine has been required for each pass, through which the material to be ground is passed from one machine to the other with an intermediate sifting. Since the structure of the mill product becomes finer from pass to pass, it is customary to let the grooves on the rollers, which are used for milling, become finer in accordance with the products. It is known that grinding is effected by two chilled rolls _s that operate together at a certain distance over its entire length, either oiler provided with corrugations without ripples, as burnishing latter, also made of ceramic materials. With some types, a roller is sometimes replaced by a segment »This is in turn provided with corrugations or is designed as a stone shell, which is paired with a stone roller. The distance between the two grinding elements has hitherto been set specifically for each individual passage in order to comply with the grinding products that are becoming finer in grain size after each passage. In the normal case, a pair, ^{i.e. two 1} VaI ζ en, of which one is movably mounted, is stored in a simple roller cage for the purpose of regulating the working gap. In the case of segments, this is usually arranged to be movable «,

So as not to have a single passage for each jade

To have to set up a roller chair ₅ attempts have been made or described in the specialist press to divide the total roller length of a chair into several parts with different corrugations ζ aiii, ^{to leave the adjustable T} 7alze as such; or to replace them with correspondingly shorter Ytalzen as shark "compartments ^ · ait Qeweils" specially adjustable storage * The latter has the disadvantage of a ^1! Roller length combination. for the intermediate storage and leads to a more complicated design with extensive changes to the previous design, the first has the disadvantage that the ivlahl gap remains the same in all compartments, which means that the grist is handled too sharply in the first compartments, i.e. chokes, and in the last Compartment is not properly composed. The different interstices in the various large, mostly triangular corrugated shapes do not change anything, as practical experiments have shown.

Object of the invention is to settle one or both rollers which cooperate in a known ^T 7eise on the divided compartments in diameter so / that give different grinding gaps. This ensures that the grist is properly processed in each compartment ^ - and that "the hollow gap from the previous compartment is set to a constant, fixed amount from the outset so that subjective factors are eliminated in the correct setting." Movable ^T- bar set correctly by the operator, taking into account the last compartment, so that the correct setting is made on all previous compartments at the same time, which previously could only be set individually.

What is particularly advantageous about the invention is the possibility of using it in all previous "Jalzenstuhl constructions" :> The rollers experience only a small "change. Without wasting a large amount of roller length, a" pair of rollers can be converted into

Divide as many and long grinding compartments as you like. Long ^1> roll chair constructions, which are cheaper to manufacture in relation to the unit of length, can be used very advantageously. Regulate the Soeisewalzen that len steady inflow of Mahlgutstroaes, are also very well be divided. Here, too, it is appropriate to zu'erhalten to different feed rates at the same speed, to vary the diameter of each compartment in the same "tone. Furthermore, a 7alze of several leaves put together or provided with fi ^a ^ ^m fntsprechnendenMantel of the invention. Also, / in a / '' alze ^ - also apply the principle of the invention.

The invention achieves this without major structural changes to the previous chairs, smaller A! To set up automatic milling, to subdivide combined medium-sized mills into a completely automatic system according to do ^ genes or other grist and to increase the number of passages in larger automatic mills by shortening the usually too long rollers of the rear mills. The use of pneumatic conveyor belts instead of elevators does not result in any difficulties. The successes lie in lighter flours and increased yield and significant labor savings. -
