Übersetzung für "Rohmühle" in Englisch

For the production of cement clinker, raw materials 1 are ground in a raw mill 2 .

All raw materials are ground together in a raw mill and at the same time dried.

The event will take place in the conference room 2 at the Rohmühle and will begin at 6 pm.

Hydrated lime can be charged into the raw mill together with the raw material constituents or directly added to the kiln feed.

In cement kiln systems, this temperature range is usually reached in the area between the raw mill and the dust collector

In the context of the production of cement, in addition, sulphur can be incorporated in the raw material in the raw mill.

The film screening followed by a discussion will begin at 6 pm in the conference room 2 at the Rohmühle.

The technique consists of optimising the raw milling process so that the raw mill can be operated to act as SO2 abatement for the kiln.

Should these prove insufficient, then there is the possibility of introducing a residual part-stream of the exhaust gases from the raw meal preheater 2 into the raw-grinding mill 4a as additional drying gases.

The mixing zone is preferably formed by a mixing silo or mixing vessel 19 which can be constructed in a known manner and in which the receiving capacity is adapted according to the operating conditions to approximately the grinding capacity (t/h) of the raw mill 9 occurring once to three times an hour.

In each case, however, the total raw material mass flow from the raw mill 9 is conveyed directly into the mixing vessel 19.

Moreover, in the case of a--desired or undesired--shutdown of the raw mill 9, from the storage silo 20 the raw meal mixture can be conveyed directly to the burning arrangement 10 or by way of the mixing vessel 19 to the burning arrangement 10 or also, in adjustable quantities, some can be conveyed directly to the burning arrangement 10 and some by way of the mixing vessel 19 to the burning arrangement 10.

In the first filling of the storage silo 20 or after a kiln shutdown without stock remaining it may further be advantageous to convey the entire mass flow from the raw mill 9 either by way of the mixing vessel 19 or directly--by way of the corresponding bucket elevator--into the storage silo 20 in order to be able to fill up the latter particularly quickly.

As can also be seen in FIG. 1, a conveyor arrangement which conveys substantially horizontally, preferably in the form of a pneumatic conveyor trough 26, can also be provided if required between the discharge duct 15 (below the raw mill 9) and the upper inlet of the mixing vessel 19.

If in the case of FIG. 2 we again consider the procedure in the case of interconnected operation (raw mill running), then a principal quantity of the raw meal mixture to be delivered to the burning arrangement 10 is conveyed directly from the mixing vessel 19 and a smaller, likewise adjustable part-quantity is likewise conveyed directly from the storage silo 20, without it being possible for the smaller part-quantity from the storage silo 20 still to be passed via the mixing vessel 19.

In direct operation of the apparatus (raw mill stationary) the raw meal mixtures produced at different times cannot be blended again, since the total quantity of the raw meal mixture required by the burning arrangement 10 is then only conveyed directly from the storage silo 20.

According to FIG. 3 the raw material ground in the raw mill is conveyed as a whole by way of the pneumatic conveyor trough 26 and the mill bucket elevator 29 into the mixing vessel 19.

If in this third embodiment direct operation must be employed (raw mill stationary), then the raw meal mixture is delivered from the storage silo 20 only by way of the mill bucket elevator 29 and the mixing vessel 19 as well as the kiln bucket elevator 30 to the burning arrangement 10.

With the aid of the proportioning belt scales 5 to 8 the individual raw material components can be proportioned according to their chemical compositions in predetermined proportions by weight or by quantity and can be jointly fed as a raw material combination to the raw mill 9, which can preferably be a roll grinding mill but, if appropriate, also a roller mill.

For this purpose material samples are removed from the comminuted material periodically at specific time intervals with the aid of an automatic material sampling station, for example at the outlet of a raw mill.

In this raw mill 9 the raw material components which can be delivered in adjustable quantities are jointly comminuted or ground to a predetermined fineness.

In so-called composite operation, dust-laden preheater waste gas 7 is at least partially guided to the raw mill 3, where raw material 6 is ground and dried by the thermal energy of the preheater waste gases.

The waste gas of the cyclone 4 and any preheater waste gases 7 which have not been directed to the raw mill 3 are supplied as a waste gas 7 ? of the cement production process to a filter 8 for dust removal.

After dinner, one should pay a visit to close Rohmühle or Pure Gold Bar where you can resume your day with a dreamlike view over the Rhine.

Stay on Rheinwerkallee until it ends at the Rhine esplanade. The seat of the Käte Hamburger Center for Advanced Study in the Humanities "Law as Culture" is a red brick villa with a white northern façade on the left side of Rheinwerkallee, across from the four-story “Rohmühle”.

For an optimal drying process, the material from the quarry should only have a low moisture content so that it can be crushed in a dry crusher, ground to powder in the raw mill and burnt in the rotary kiln without further pre-treatment.

Also unplanned stops of the raw mill during group operation, coupled with an immediate change-over to the mode of direct operation, were mastered.
