Hammer mill with around a vertical shaft rotating impact tools

The invention relates to a hammer mill with a vertical one Shaft rotating impact tools and axial feeding of the material to be shredded

With the novel arrangement according to the invention, the possibility be created to break down moist corn kernels or similar moist grist by grinding as finely as possible and subsequent silage to fully maintain the feed value of the property

In order to make a hammer mill suitable for this purpose, according to the invention A cutting tool set rotating in a housing is connected upstream of the striking tools on the same axis The main effect is that the teeth of the toothed disks belonging to the cutting tool are spaced a little apart from the inner wall of the housing, as this achieves the greatest degree of fineness of the comminution.

The cutting tool set is put together according to the water content of the maize kernels to be processed. Become useful one behind the other on the same axis in the direction of flow of the goods one or more two-armed knives offset from one another and one or more toothed disks arranged on the drive shaft. Instead of the toothed disks, one or more cutting disks can also be arranged downstream of the knives.

The control of the degree of fineness of the ground material is also used by arrangements through which the cross-section of the discharge openings the hammer mill is changeable, whereby the grist is retained more or less long in the grinding chamber.

The upstream cutting tool set can advantageously be removed connected to the hammer mill, the hammer mill even without cutting tools for grinding dry material at any time to be able to use. In this ball it is advisable to replace the upper part of the mill. Instead of a cylindrical one Housing a cover with a feed and metering device is placed, which with the same closures is held and which feeds the grain centrally. This ensures that the grain is perfectly even is married and there are also no disadvantages those with the otherwise usual feed and metering devices arise, which are hung in the cylindrical vat for the purpose of grain grinding (contamination of the ground material » Sticking to the housing walls, etc.).

FIG. 1 shows a hammer mill with an upstream cutting tool set _β. The material to be comminuted is fed through a funnel (1). It is first picked up by the rotating pre-shredder (2) and then falls onto the track disc (3). It can be a single tooth disc or several discs arranged one above the other. The toothed disks revolve at a small distance from the inner wall of the housing (^) and preferably work together with a counter-support (5) in such a way that the material to be ground is prevented from falling through too early. The ground material then falls further down onto the rotating hammer set (6), which takes over the final shredding and which throws the end product outwards through the discharge nozzle (7) «

Figure 2 shows the same machine, namely after the cylindrical housing against a cover with a central feed and dosing device has been replaced »
