Definitions
- the invention relates to a roller press with at least two rotatably mounted and oppositely formed, separated by a roller nip rollers, wherein at least one roller is driven via a gear.
- roller presses for crushing eg limestone, clinker, ores, minerals or building rubble
- the individual pieces of ground material are drawn by friction into the nip of the roller press and pressed when using a high pressure and crushed each other.
- the pressure in the nip is selected by appropriate pressure means, which control the position of the rollers and thus maintain the pressure in the nip, so high that the millbase is pressed into so-called slugs.
- These pellets of crushed material are then dissolved with low energy expenditure and thereby disintegrate the slugs in finely crushed material.
- the surfaces of the rollers are exposed to a high wear stress due to the high compression pressures and pressing forces, especially when a non-comminutable foreign body, eg. B. a lost hammer of an upstream hammer crusher in the nip device.
- a non-comminutable foreign body eg. B. a lost hammer of an upstream hammer crusher in the nip device.
- the regrind itself carries the surfaces of the rollers from strong.
- this measures are used to protect the surfaces, such as the formation of a good bed between applied to the surface hard bodies, wherein the ground material is pressed and comminuted in the good bed, yet the grinding rollers of a roller press are exposed to a very strong wear, so that It is necessary to replace the grinding rollers at regular intervals in order to rebuild them.
- the machine frame is constructed so that individual frame parts can be folded down and thus support the removal of a roller.
- the forces are absorbed in the nip by mounted between the rollers mechanisms to keep the sizing of the frame as low as possible, which means at mill weights of 50 tons and much more a significant workload.
- the object of the invention is therefore to provide a connection between drive and grinding roller available, which allows easy and easy disassembly and reassembly of the shaft-drive connection.
- the object according to the invention is achieved in that a clutch is arranged between the transmission and the at least one driven roller.
- the arrangement of a coupling between the shaft and drive allows a quick and easy release of the shaft-drive connection during disassembly and subsequent assembly of the roller press during regular replacement of the grinding rollers. It has proven to be advantageous if the shaft has a clutch disc which is shrunk onto the shaft. In addition, a mounting by flanging or by welding is also suitable. The clutch disc is gripped by releasable dogs, whereby the torque is transmitted to the clutch disc via the drivers and to the shaft via the clutch disc. To loosen and reassemble the connection between the drive and shaft reduces the necessary assembly work on the mounting or dismounting of the driver, so that a very complex and complex alignment of drive and shaft for connecting by shrinking is no longer necessary.
- the drivers are designed so that they firmly grasp the clutch disc in the idle state and without applying a force.
- the drivers have a mechanism, such as a simple screw or a system for opening, on or an electromechanical or hydraulic system, the electromechanical or the hydraulic system by appropriate transmission paths, such as sliding contacts or rotatable liquid seals always , So even during operation of the grinding roller, can be triggered.
- a release of the clutch during operation has the advantage that the grinding roller has a possibility for emergency braking. For example, if the roller press has risen and the drive could possibly be damaged.
- a triggering during operation in order to reduce the maximum torque that transmits the clutch to a maximum.
- electrically or hydraulically triggered drivers can affect a sensor that detects the torque directly or indirectly, the release and re-tightening the driver. But it is also possible to only set so that from a certain torque of the driver slips on the clutch disc.
- the clutch consists of a brake which is commonly used in wind turbines.
- brakes for wind turbines are cheap available, so that their use in roller presses is economical.
- brake calipers sit with a corresponding brake pad on a brake disc.
- the brake disc assumes the function of the clutch disc, which is arranged on the shaft of the grinding roller and the calipers are fixedly connected to one of the clutch disc opposite drive pulley.
- the calipers are formed to a small extent radially displaceable and maintain their rotational position by fixing the brake shoes on the brake disc. Since the calipers are firmly connected to the drive pulley, the torque is transmitted from the drive shaft via the caliper to the brake disc as a clutch disc.
- Figure 1 is a side view as a section through an inventive
- Figure 2 is a plan view of the coupling.
- FIG. 2 shows a plan view of the coupling 1 in which in the foreground the coupling disk 10 is enclosed by the three drivers 7, 7b and 7c distributed uniformly around the circumference of the coupling disk 10.
- the drive pulley 6 is shown, on which the drivers 7, 7b and 7c are mounted so that they have a small radial clearance, so as to play a height at an offset between the two centers of rotation of the drive shaft 4 and Balance shaft 3 of the grinding roller.
- the clutch disc (10) is a multi-disc arrangement, comparable to a multi-disc brake, and an internal ventilation, as it is known from disc brakes has. LIST OF REFERENCE NUMBERS
