Hammer mill

The innovation relates to a hammer mill, especially for grinding wet maize including the spindles after the upper ^ concept of claim 1.

When grinding wet maize to be ensiled with spindles by means of a hammer mill, it has been found that the arrangement of a ^ The size of the smaller sieve plate often determines the grinding capacity is reduced, as fibers and piston parts get stuck in the holes.

which can easily lead to a blockage, even with large holes | leads. This is due to the fact that maize :, -z »B. by harvesting

on different days, very different amounts of moisture L

contains and the fiber formation of the spindles and blades in the mill j

also not determinable in advance depending on the maize variety I

The task of the innovation is therefore to fix fibers and spindle particles with partial or complete Avoid clogging of the beater mill.

7812278 1 / L 09.78

This object is achieved in that in the beater mill mentioned in the preamble of claim 1, the annular slot between formed a rotating disk parallel to the clubs and the parallel opposite end face of a cylinder ring is, and that the cylinder ring and the disk are adjustable relative to each other parallel to the mill shaft.

It is thus possible, depending on the occurrence, of fibers or the like getting caught by the rotating disk to be avoided and by choosing the width of the ring slot to adjust the fine grain size of the ground material, e.g. to increase it after a short test run or to reduce the size so that it is possible to then let the beater mill work continuously.

The innovation is explained below with reference to the drawing, in which two exemplary embodiments are shown. Show it:

Fig. 1 a beater mill in vertical axial section, |

2 shows a partially enlarged axial section through a modified version of the hammer mill.

According to the example of FIG. 2, the hammer mill consists of a housing 1 with a pivotable cover 2, which the corn with spindles is supplied via the inlet 3, the ground material through

a lower outlet 4 is removed. In housing 1, 2 is with the shaft that can be driven by a motor 5 is rigidly coupled to a hub 7. The circumferential sleeps are on a radial flange 8

ger 9 arranged pivotably on bearing journals 10.

At a distance from the clubs 9, an annular disk 11 is rigid with the radial flange 8 through the bearing journals 10 and spacer rings tied together. In the housing 1, a cylinder ring 12 is also provided according to the innovation, which open after pivoting of the cover 2 or of the cover 2 can be adjusted parallel to the shaft 6 by several screws 13 is / and which forms an annular slot 14 between one of its end faces and the rotating disk 11. By the possible axially parallel adjustment of the cylinder ring 12 is the ring slot 14 in width to the type and humidity of the to grinding wet corn with spindles adaptable at any time.

Is it advantageous between the clubs 9 and the disc? 11 to pivotably connect the connecting bolts 'B' striking rods 15 in order to also achieve comminution behind the beaters 9 and constant movement of the commodity in front of the disc 11. Furthermore, the disk 11 is equipped in the vicinity of its overhang with pivotably mounted clearing beaters 16 in order to prevent ground material from attaching to the inner circumference of the housing 1. I.

According to the example of FIG. 2, in which the same reference symbols are used for the same parts are provided, instead of the axially adjustable cylinder ring 12 of Figure 1, a on the inner circumference of the cast Housing part 1a adjacent cylinder ring 12a, which is detachably supported on the end face facing the clubs 9 with stops 12b is provided, ι which between the housing part 1 a and the cover 2 be clamped so that the cylinder ring 12a is fixed. In this one Case, a bush 17 with a radial annular flange 18 is mounted on the shaft hub 7 with the interposition of a sliding bush, with which the circumferential screen disk 11 is firmly connected, the scope of which is at most equal to the outer circumference of the cylinder ring 12a. The socket 17 with flange 18 and washer 11 are secured by two screws axially adjustable in order to adjust the width of the annular slot 14 depending on the humidity and the type of material to be ground be able. This design makes it possible to use the entire grinding set inside the mill housing to be exchanged for a grinding set for dry, granular grist without any changes need to be made on the mill housing.
