Definitions
- the invention relates to an impact mill, in which at the Good inlet opening opposite side of the housing below the impact devices a grinding track is arranged, the At least partially engages rotor.
- a grinding track is arranged at the Good inlet opening opposite side of the housing below the impact devices, the At least partially engages rotor.
- the object of the invention is to such an impact mill achieve that when swiveling the rear wall of the housing a movement the grinding path is reached, which is a larger horizontal Component and has a larger rotation, so that the grinding track cannot collide with the rotor and in the End position lies flat, so that the replacement of wear parts is made much easier than with the known Impact mill.
- the grinding track gets into a End position in which they are essentially below the the rotor axis is located horizontal plane, so that it can serve as a stand area for the personnel who operate the Impact bars of the rotor and the baffle plates on the impact units has to be replaced.
- the grinding track on an arranged on the housing of the impact mill approximately horizontally running rail or plate rests slidably and her lower part via a first handlebar with the pivotable rear wall on one above its pivot axis lying area and its upper part over a second Handlebar with the rear wall at a greater distance articulated from the swivel axis is.
- the main difference compared to the known impact mill is that the grinding track at both the top and also on the lower part with the swiveling rear wall is connected, in both cases by means of both ends freely pivoting handlebar.
- the grinding track at both the top and also on the lower part with the swiveling rear wall is connected, in both cases by means of both ends freely pivoting handlebar.
- the movement of the grinding track initially proceeds in the desired manner flatter if in a further embodiment of the invention the pivot points of the handlebars on the grinding path are larger Have a distance from each other than the articulation points of the Handlebars on the swiveling rear wall, and the upper one second handlebars in the closed position of the rear wall has approximately horizontal position. This will make it even bigger Measure a collision of the grinding path with the rotor during the Swinging out of the rear wall avoided, being in the end position the swung out back wall the grinding track one for your Maintenance and the other parts of the impact mill are nevertheless suitable flat position.
- the handlebar that connects the lower part of the grinding track with the rear wall of the housing connects can in an advantageous embodiment the invention as by means of a hydraulic cylinder-piston unit variable-length adjustment link formed with which the grinding gap between the grinding track and the rotor impact circle can be adjusted. It is advantageous that the greater distance between the articulation points Handlebars on the grinding track also provide better leverage for that hydraulic cylinder-piston unit for adjusting the Grinding track results.
- the upper handlebar can also be used to change the distance of the upper end of the grinding track variable in length from the impact circle of the rotor be provided. Because this change is rare actuation by a spindle is sufficient and mother.
- An independent adjustability of the lower one and the top of one cooperating with an impact mill rotor is from DE-GM 1 764 034 already known.
- the The position of the grinding path is not determined by the handlebars alone. Therefore there is one on the fixed part of the housing horizontal rail or plate provided, on which the grinding track rests and which the through the regrind absorbs forces coming on the grinding track.
- a flexible storage of the rail or plate can dodge the grinding track if the forces are excessive. It is also possible the rail or plate by means of a predetermined breaking element to be stored, so that they are inadmissibly high can swing a pivot axis down. The grinding track can then dodge hanging down on the two handlebars.
- the main parts of the impact mill are the housing 1, the in this mounted rotor 2, impactors 3 and a grinding track 4.
- the rear wall 5 of the housing 1 is around at its lower Axis 6 provided at the end on the fixed lower part 7 the housing 1 is pivotally mounted to the outside.
- Hydraulic cylinder-piston units on both sides of the housing 28 provided (Fig. 2).
- the impact units 3 are on the rear wall 5 of the housing about axes 8 pivoted and hydraulically controlled Handlebar 9 adjustable in position to the rotor 2.
- the grinding track 4 provided with wear bars 10 is by means of two handlebars or handlebar pairs 11 and 12 with the rear wall 5 connected and lies with the lower edges 13 of their rear Reinforcing ribs 14 on a plate 15.
- the Plate 15 is at the rear in the housing part 7 about an axis 16 swiveling and flexible in front.
- the front storage may be inadmissible to avoid damage when occurring high forces on the grinding track 4 also by means of predetermined breaking elements 17 can be canceled so that they together with the Plate 15 can pivot down about the axis 16 and thus, for example, uncrushable parts of the regrind allows the exit from the impact mill (see Fig. 4).
- the grinding track is at its lower end by means of the handlebar or handlebar pair 11 and at their upper end by means of Handlebar or handlebar pair 12 connected to the rear wall 5, the articulation point 18 of the lower link 11 is less Distance from the pivot axis 6 of the rear wall 5 has than the pivot point 19 of the upper link 12.
- the distance between the articulation points 25, 26 of the handlebars 11, 12 on the Grinding track 4 is preferably larger than the distance between the pivot points 18, 19 on the rear wall 5; the driver 12 points in the closed state of the impact mill housing an approximately horizontal position.
- the lower Handlebar 11 is with a hydraulic cylinder-piston unit 20 provided by which its length for the purpose of Changed the setting of the grinding path to the rotor impact circle 21 can be.
- the grinding track 4 moves with the Lower edges 13 of their reinforcing ribs 14 on the plate 15, with a slight tilting movement of the grinding track.
- the lower edges 13 are slightly convexly curved.
- the plate 15 is through a transverse double T-beam 22 stiffened.
- the grinding track 4 leads when opened the rear wall 5 a longitudinal movement away from the rotor and at the same time a rotational movement outwards (in Fig. 2 counter clockwise) so that their wear bars 10 from freely accessible from above and also good as a stand for Fitter are suitable, the blow bars 23 on the rotor 2 and to replace the baffle plates 24 on the impact units 3 to have.
