Definitions
- the invention relates to a machine interface between a grinding bowl of a vertical mill and a drive of the grinding bowl, a drive and a vertical mill.
- Fig. 1 is a whale zenmühle with a rotating about the vertical axis meal ⁇ bowl 7 and then grinding rollers rolling 4. The drive of the grinding table via a gear 9. Such mills, which inter alia used in cement production, referred to as vertical mills.
- a hot gas generator is used in cement production during the grinding process.
- a temperature of 80 ° C to 130 ° C is reached in the grinding chamber.
- the oil coolers used for cooling the drive ie for cooling the gears and the bearings, must be made larger than would be necessary without heated grinding space. It is an object of the present invention to provide an improved machine interface between a grinding table of a Ver ⁇ tikalmühle and len formatzustel- a drive of the grinding table, and a drive and a vertical mill.
- the machine interface according to the invention is located between a grinding bowl of a vertical mill and an on ⁇ operation of the grinding bowl.
- the machine interface is designed so that the grinding bowl and the drive are thermally decoupled ⁇ mix. Compared with conventional machine interfaces in vertical mills, a heat flow directed from the grinding bowl to the drive is thereby substantially reduced.
- ⁇ temperature difference.
- a reduction of this heat flow is by a reductive ⁇ tion of the thermal conductivity ⁇ and / or the area A of Ma ⁇ schin interface achievable.
- the present machine interface is a particularly cost-effective and robust solution, since it is mechanically very simple.
- the oil cooler of vertical mills can be designed smaller than before. A rough estimate has shown a possible cost saving of about 25% compared to conventional mills. This also leads to lower follow-up costs for the plant operator, eg a saving of electricity costs by the smaller oil supply system.
- a material which is thermally insulating against metal is arranged between the grinding bowl and the drive. Additionally or alternatively, a contact surface between the grinding bowl and the drive can be designed as small as possible for a given carrying capacity.
- a thermal insulation layer is thus arranged.
- Preferred heat-insulating materials meet the requirements of mechanical strength (Tragfä ⁇ ability, shear strength, etc.) on the machine interface and have a low compared to metal bathleitfä ⁇ ability.
- Preferred heat-insulating materials have a thermal conductivity ⁇ ⁇ 1 W / (mK), more preferably ⁇ ⁇ 0.5 W / (mK).
- Suitable materials include ceramic or plastic in the form of discs or coating. The greater the thickness d of the insulating material, the greater its insulating effect, and thus the reduction of the heat flow.
- the bearing surface is reduced as much as mög ⁇ Lich. Proportional to the reduction of the contact surface, the heat flow through the machine interface is reduced.
- a preferred embodiment of the invention is a drive, in particular a transmission, with a suitable flange for connecting a grinding bowl, wherein the flange is designed as a machine interface as described above.
- a further preferred development of the invention is a vertical mill with a machine interface as described above.
- Fig. 1 is a first sectional view of a vertical mill
- FIG. 2 shows a first embodiment of the machine interface
- FIG. 3 shows a further embodiment of the machine Thomasstel ⁇ le
- Fig. 5 is a further sectional view of a vertical mill
- Fig. 1 shows a section of a vertical mill 3 with a rotatable grinding bowl 2 and a drive 4 of Mahlschüs- sei 2, which causes the rotation of the grinding bowl 2.
- the Ver ⁇ tikalmühle 3 includes a machine interface.
- the drive 4 has a drive on its vertically upper side. flange 40, which is suitable for connecting the grinding bowl 2.
- the vertically upwardly directed side of the drive flange 40 forms a contact surface 7, on which the grinding bowl 2 rests on the drive 4.
- the contact surface 7 of grinding bowl 2 and drive flange 40 thus forms ⁇ with the said machine interface.
- the grinding bowl 2 is arranged in a grinding chamber 9, wel ⁇ cher is limited by a housing 8. By heating the grinding chamber 9, a heat flow 10 is produced, which flows from the grinding bowl 2 via the machine interface 1 to the drive 4.
- Maschi ⁇ nenschnittstelle 1 is now configured such that the directed from the meal ⁇ bowl 2 to the drive 4 lent heat flow 10 essential is hindered.
- Fig. 2 shows a first embodiment of the invention.
- a heat-insulating layer 5 for example in the form of a mat, a disc or a coating, is arranged on the machine interface 1 between the grinding bowl 2 and the drive 4.
- the grinding bowl 2 and the grinding bowl 2 tra ⁇ ing part of the drive 4 are usually made of a metal such as steel with a thermal conductivity ⁇ in the range of about 15 to 60 W / (mK).
- the heat-insulating layer 5 against DA consists of a material which both the require ⁇ extensions (to the mechanical load-bearing capacity,
- Shear strength, etc. meets as well as having a relatively low thermal conductivity.
- a suitable material is e.g. Durobest from the manufacturer AGK Hoch intricateswerktechnik GmbH, Dortmund (DE).
- the material series Durobest 110-280 comprises hard papers and hard tissues with a thermal conductivity ⁇ in the range of 0.18 to 0.3 W / (m-K).
- Fig. 3 shows a further embodiment of the invention.
- the contact surface 7 is not formed on the entire surface of the machine interface 1 between the grinding bowl 2 and the drive 4, but by a formation of recesses 6 on the upwardly directed side of the drive flange 40th reduced in area. It is advantageous to reduce the Kunststoffflä ⁇ che of grinding bowl 2 and drive 4 as far as it is possible in compliance with the static requirements. As a consequence of the reduction of the area results in a reduced compared to a full-area contact surface, in the optimal case minimized heat flow.
- FIG. 4 shows a further embodiment of the invention, in which the embodiments according to FIGS. 2 and 3 are combined with one another.
- the reduced by a formation of recesses contact surface 7 is covered by a heat ⁇ me insulating layer 5.
- Fig. 5 shows a further section of a vertical mill.
- a grinding bowl 2 Via a drive element 4, comprising an electric motor and a planetary gear, a grinding bowl 2 is angeord ⁇ net on a horizontal An ⁇ drive flange 40 of the drive 4.
- the grinding bowl 2 is - seen along the axis of rotation of the grinding bowl 2 - formed substantially annular and enclosing an air space 11 in its interior.
- the resting on the drive flange 40 of the drive 4 lower ⁇ side of the grinding bowl 2 has a ring shape, so that the contact surface between the drive flange 40 and the grinding bowl resting thereon 2 also has a ring shape.
- He ⁇ invention according to the contact area 7 along the Maschi ⁇ nenroughstelle 1 is now so formed that the grinding table 2 and the drive 4 are thermally decoupled, for example by turning on addition of a thermally insulating layer between the bottom of the grinding table 2 and the upper surface of the drive ⁇ Flange 40 and / or an areal reduction of Kon ⁇ tact surface of grinding bowl 2 and drive 4. In this way, the directed from the grinding bowl 2 to the drive 4 heat flow 10 is substantially hindered.
