Definitions
- the invention relates to a roller mill with a grinding table, at least one standing with the grinding table Abrollengriff grinding roller, a main drive system for driving grinding roller and / or grinding table and an auxiliary drive for driving the grinding table. Furthermore, the invention relates to a method for driving such a roller mill.
- a large central gear below the grinding plate which is driven by a main drive or an auxiliary drive.
- the auxiliary drive provides when starting the mill as support for the main drive for a high torque on the grinding table.
- he is able to clear a completely full after a emergency stop mill again and thus to enable a new mill start. Furthermore, it ensures a slow turning of the grinding table during assembly and maintenance work in the mill.
- auxiliary drive is connected via a pinion with a large ring gear on the grinding table.
- the invention is therefore based on the object to provide a roller mill with a cost-effective auxiliary drive for the grinding table and a method for operating a roller mill, so that a safe mill start and easy maintenance of the mill is possible.
- the roller mill according to the invention essentially consists of a grinding table, at least one grinding roller which is in rolling contact with the grinding table, a main drive system for driving a grinding roller and / or grinding table and an auxiliary drive for driving the grinding plate.
- the auxiliary drive comprises at least two linear drives for rotating the grinding table and a control device for the individual control of the linear drives in the sense of an uninterrupted, ie continuous rotary motion.
- the auxiliary drive for the grinding table can reliably ensure during the starting process that sufficient material lying in front of the grinding rollers is brought to it, so that the grinding rollers securely engage in the material to be ground, and thus they can transmit their drive power.
- the torque required for this purpose can lie at a factor of 1.75 to 2.4 above the design torque on the mill axis.
- the auxiliary drive can also be used during maintenance and installation work. So it is possible with the linear drive to turn the grinding table step by step for assembly work and to position.
- the linear drives are connected to the grinding table via at least one coupling gear, which is preferably formed by a ratchet wheel fastened to the grinding plate.
- the linear drives can also be formed particularly cost-effective by hydraulic cylinders that provide a high power density at a relatively low price at the same time. In conjunction with a hydraulic supply and a corresponding control unit, these can be used to set the grinding table in rotation via a ratchet wheel mounted on the grinding table base and designed as a coupling gear.
- linear drives are expediently arranged at an angle +/- 10 ° to Mahltellertangente. With a correspondingly large pitch circle diameter of the ratchet wheel, the provision of high drive torques is ensured in this way.
- the linear drives between a drive position and a non-drive position are adjustable, the linear drives in the drive position with the grinding table, in particular with the attached ratchet, for rotating the same are in operative contact, while the contact with the grinding table in the non-drive position is canceled.
- the transition from auxiliary to the main drive of the roller mill can be done continuously and without a jump in speed.
- a linear movement of the linear drives can be converted into a rotational movement of the grinding table. It is expedient if the forward and return stroke of the linear drives are executed offset in time. For example, at least one linear drive can be withdrawn from its outer end position, while at least one other
- Linear drive still performs its working stroke. In this way an uninterrupted rotation is possible.
- control device the linear actuators in case of need, especially during assembly and maintenance work, so control that the grinding table is stopped at certain positions.
- the lifting speed of the linear drives for realizing different speeds of the grinding table is variably adjustable. With such a control of the grinding table this can be used, for example, for welding a wear protection on the grinding path.
- 3 is a detail view of the auxiliary drive in the drive position, a schematic representation of a Anpresssystems the auxiliary drive, 5 is a sectional side view of the roller mill in the region of the auxiliary drive,
- FIG. 6 is a sectional view long the line A-A of Fig. 3,
- Fig. 8 is a plan view of an auxiliary drive for both directions of rotation.
- the roller mill shown in Fig. 1 consists essentially of a grinding table 1, at least one standing with the grinding table Abrollengriff grinding roller 2, 3, a Hauptantriebssytem 4, 5 for driving the grinding rollers and an auxiliary drive 6 for driving the grinding table 1.
- a grinding table 1 at least one standing with the grinding table Abrollengriff grinding roller 2, 3, a Hauptantriebssytem 4, 5 for driving the grinding rollers and an auxiliary drive 6 for driving the grinding table 1.
- auxiliary drive 6 for driving the grinding table 1.
- too more than two grinding rollers, in particular three or four grinding rollers are provided.
- the auxiliary drive 6 has a fixedly connected to the grinding table 1 ratchet wheel 60 and four evenly distributed over the circumference of the ratchet wheel 60 arranged linear drives 61 to 64.
- the ratchet wheel 60 consists of two mutually spaced pawl plates 60a, 60b, in the pawl recesses 60c are formed.
- the attachment of the ratchet wheel 60 to the grinding table 1 is preferably done via a screw connection 8 on a race 10a of Mahltellerlagerung 10. This allows the complete module to be pre-assembled and delivered independently of the grinding table 1 to the site.
- the linear drives are arranged tangentially to the ratchet wheel 60 and are preferably formed by four evenly distributed over the circumference hydraulic cylinder.
- the linear actuators are connected via a housing-fixed pivot pin 65 rotatably connected to a bracket 66 and a grinding table 10 storage.
- the linear drives 61 to 64 have pressure pins 67, which engage in latch recesses 60c in such a way that the linear extension movement of the linear drives is converted into a rotary motion of the grinding table 1. If a linear drive has reached its end position, its piston rod 68 returns to its starting position.
- the linear actuators are pressed by a contact pressure system 69 in the direction of mill axis 11, so that the pressure pin 67 moves along the outer contour of the ratchet wheel 60 and always bears against it.
- a control device 7 evaluates measuring signals from a rotary encoder and other sensors (not shown), which provide information about the positions and speeds of the grinding table 1 and the linear drives 61 to 64.
- the control device 7 controls the travel paths of the linear drives 61 to 64 and adjusts them to each other, so that all linear drives have different extension distances. This makes it possible to combine the travels of the linear drives so that always extend three of the four linear drives and rotate the ratchet wheel 60 further, while the fourth linear drive moves back in rapid traverse and threads into a new latch recess 60c. Then has the next linear drive reaches its end position, this moves back to its initial position and the remaining three continue the rotation. This successive interplay of the linear drives 61 to 64 can take place continuously, so that the rotation of the grinding table is also continuous and uniform.
- the pressure pin 67 engages in the latch recesses 60c of the two latch plates 60a, 60b.
- the pressure pin shaft 67a is connected via a joint eye 67b with the piston rod 68, so that a uniform loading of the pawl recesses 60c of the two latch plates 60a, 60b is established.
- sleeves 67c, 67d on the pressure pin shaft 67a the materials of the contact partners can be adjusted to each other. At the same time this allows easy replacement of the sleeves 67c, 67d when worn on the pressure pin 67th
- Auxiliary drive 6 and the main drive systems 4, 5 of the grinding rollers may differ at this time, it is necessary to ensure a smooth transition between two types of drive. This is achieved in that the ratchet wheel, similar to an overrunning clutch or a freewheel, can rotate freely while the linear drives 61 to 64 are pressed against the Anpresssystem 69 to the outside.
- the linear drives 61 to 64 are moved to the non-drive position shown in FIG. 7, so that the pressure pins 67 are set laterally outward and the ratchet 60 can rotate freely and without contact to them.
- the auxiliary drive 6 can be used in addition to its actual function when starting the mill during maintenance. So it is possible in Mühlenein- and conversions the grinding table 1 in a certain To position the rotary position or to slowly rotate the grinding table during welding of a worn grinding track and to regulate this rotation. As a result, an otherwise required, separate maintenance drive for the grinding table 1 can be omitted.
- Fig. 8 shows a variant of a ratchet wheel 60 'with opposing pawls 60' d. If, in addition to the linear drives 61 to 64 described above, at least one further linear drive 6 ⁇ is arranged in opposite directions, then the grinding table 1 can be rotated in both directions of rotation. In this constellation, however, the above-mentioned overtaking of the ratchet wheel and the lengthening of the pressure pin 67 at the edge of the ratchet wheel 60 'is no longer possible. Therefore, at least in this variant, an actively controlled, radial pivoting in and out of the linear drives is indispensable.
- auxiliary drive 6 described above is thus able to assume the following function with a corresponding configuration:
