Definitions
- the present invention relates to a mill for grinding of coarse stone-like bulk material, for example ore or coal, having a rotatable about a vertical axis of rotation Mahltel ⁇ ler, wherein the grinding table is at ⁇ drivable by an electric motor which has a motor shaft with a shaft axis ⁇ ,
- Such mills are well known and are ⁇ example, by the company Polysius AG, Germany, under the Ty ⁇ penbezelen Dorol and quadrupole.
- the mill has a grinding chamber 1.
- Mahl ⁇ room 1 has a Mahlraumteil 2 and a circulating around the grinding chamber 1 Mahlraumwand 3.
- Mahlraumboden 2 On the Mahlraumboden 2 a grinding table 4 is mounted such that it is rotatable about a vertical axis of rotation 5.
- the grinding table 4 is drivable ⁇ bar by means of an electric motor 6.
- the electric motor 6 has a motor shaft 7 with a shaft axis 8.
- the electric motor 6 is arranged laterally below the grinding table 4.
- the shaft axis 8 extends hori zontal ⁇ .
- the motor shaft 7 acts via a deflection or angle ⁇ gear 9 - eg a bevel gear - on the grinding table 4.
- the deflection gear 9 causes in addition to the deflection a Implementation of a relatively high speed of the electric motor 6 to a much lower speed of the grinding table. 4
- the grinding chamber 1 is in a known manner - for example by means of a Schuttloise not shown - coarse, rock ⁇ like bulk material 10 is supplied, for example, coal or ore lumps. Due to the centrifugal force, the bulk material 10 is in the direction of the grinding chamber wall 3 radially outward ⁇ leads. There, the bulk material 10 is ground by means of grinding rollers 11, which roll on the grinding table 4. The grinding rollers 11 are not usually driven by itself. However, driving the grinding rollers 11 would be possible.
- the crushed bulk material - to distinguish it from the unground bulk material 10 referred to as regrind 12 - is discharged in a known manner from the grinding chamber 1, for example by means of a blower, not shown.
- the well-known mill works quite well, but is relatively expensive and expensive.
- the deflection gear 9 is also relatively susceptible to interference and requires high maintenance.
- the object of the present invention is to improve the known mill so that it is easier and less expensive to produce, is easier to maintain in continuous operation and has a lower susceptibility to interference.
- the object is achieved in a mill of the type mentioned above in that the electric motor is located directly under the grinding table and the shaft axis is perpendicular.
- the motor shaft directly - ie without intermediate gear - is connected to the grinding table. If a gearbox is available, the motor shaft is still connected to the grinding table only via a gearbox.
- the transmission may include a transmission input shaft and a transmission output shaft, having parallel axes of rotation to one another ⁇ in the inventive embodiment.
- the axes of rotation of the transmission input shaft and the transmission output shaft (and consequently also the shaft axis and the rotation axis) even aligned.
- An example of a transmission having tationsachsen aligned Ro is a planetary gear that includes a sun gear, at least one planet gear and a ring gear ⁇ .
- Transmission input shaft and the transmission output shaft together ⁇ act.
- the transmission output shaft with the sun gear, the ring gear or the bearing of the planetary gear rotatably verbun ⁇ be the.
- the planetary gear which may Gereteein- input shaft and the transmission output shaft is not the same element (sun gear, ring gear, storage of the planet gear) may be ver ⁇ prevented.
- the motor shaft is connected to the sun gear.
- the grinding table is rotatably connected in this case either with the ring gear or with the storage for the at least one planetary gear.
- the electric motor is preferably designed as a slow-speed, high-pole drive. It can alternatively be designed as an asynchronous motor or as a synchronous motor. In the case of a synchronous motor, the drive may alternatively be electrically or permanently magnetically excited.
- the electric motor can furthermore be designed alternatively as an internal rotor motor or as an external rotor motor.
- the supply of the electric motor can be done directly from the supply network or - preferably - via a converter.
- FIG 2 shows a grinding table with electric direct drive and FIG 3 and 4 grinding plate with drive via a transmission.
- the present invention will be further described in connection with a permanent magnet synchronous motor, which is designed as an external rotor motor.
- a permanent magnet synchronous motor which is designed as an external rotor motor.
- an electrically excited synchronous motor or an asynchronous motor instead of the permanently excited synchronous motor and / or to design the motor as an internal rotor motor.
- the electric motor 6 is arranged directly under the Mahltel ⁇ ler 4. It has a stator winding 13, which is fastened to a stator holder 14. The stator winding 13 cooperates with a rotor 15, which has permanent magnets 16 in the present case.
- the rotor 15 is preferably bell-shaped. It can be gela ⁇ siege on the motor shaft 7 or complete it.
- the shaft axis 8 of the motor shaft 7 extends perpendicular to FIG 2.
- the motor shaft 7 is in the embodiment of FIG 2 directly - ie without interposing a gear - connected to the Mahltel ⁇ ler 4.
- the shaft axis 8 of the motor shaft 7 is therefore in alignment with the axis of rotation 5 of the grinding table 4.
- the grinding table 4 can be supported radially outside and / or between its radially outer end and the motor shaft 7.
- the rotor 15 may even be identical to the grinding table 4.
- the grinding table 4 is connected to the motor shaft 7 via a gear 17.
- the transmission 17 has a transmission input shaft 18 and a transmission output shaft 19.
- the transmission input shaft 18 and ⁇ the transmission output shaft 19 have rotational ⁇ axes 20 which are parallel to each other.
- the rotation axes 20 can be offset from each other. Preferably, however, they are aligned with each other.
- the gear 17 is designed as a planetary gear 17. It has a sun gear 21, at least one planet gear 22 and a ring gear 23. According to the Substituted ⁇ staltung of FIG 4, the motor shaft 7 is rotatably connected with the sun gear 21st
- the grinding table 4 is rotatably connected according to FIG 4 with the ring gear 23.
- the at least one planetary gear 22 is rotatably mounted on a bearing 24.
- the bearing 24 is rotatable relative to the sun gear 21 and relative to the ring gear 23.
- the grinding table 4 could be rotatably connected to the storage 24.
