Hammer mill

The innovation relates to an impact mill, at the outlet provided with tan-.gentialem housing, a drive motor is flange-connected with the vertical shaft, sitting on the rasp bars and a paddle wheel ^i, between which a fixed annular screen is provided.

In recent times, efforts have been made to marry regrets and straw and to add other feed.

In order to be able to do this with a known hammer mill, there is The innovation is that in the beater mill mentioned at the beginning, the open end face of the mill housing has a bottom open cylindrical storage container with upper throw for hay and straw is connected and that the blow bars with one they are preceded by a rotating distributor disk, between the circumference and the storage container an annular gap for the supply of the goods to the blow bars.

With this solution, hay or straw can be poured into the specified amount cylindrical storage container are thrown, which is detected by the distributor disc and fed to the beater bars of the mill

through which the material is crushed until it is through the downstream ring sieve by means of the negative pressure generated by the paddle wheel to the tangential mill outlet with connected conveying line can pass through. This enables hay and straw to be ground in a simple manner using a known hammer mill.

In order to avoid a backlog of the goods in the storage container, a narrow sheet metal strip in the form of at least one loop winding is connected to the inside of the storage container that the backwater is avoided.

The innovation is explained below with reference to the drawing, which shows a vertical axis section through the hammer mill with the upper storage container reproduces.

The device for grinding hay and straw consists of a known one Beater mill with flanged drive motor 1, the vertical one Shaft 2 is mounted in a stand 3. The motor housing carries the tangential outlet 4 and connected delivery line provided housing 5 of the beater mill. The blow bars 6 and a paddle wheel 7 are on the shaft 2 at the level of the tangential outlet 4 attached. The housing carries a fixed ring sieve 8 downstream of the blow bars 6 and guide plates 9 and 10 through which the ground material is fed to the paddle wheel 7 radially inwards.

According to the innovation, the upper end face of the mill housing 5 is open and a cylindrical storage container 11 closes here with an upper slot 12 for hay and straw on the mill housing on.

With the drive shaft 2 is a distributor disk in front of the blow bars 6 13 connected, the T "it runs around the blow bars 6 and which is provided with milling elements 14 distributed on its surface Milling members 14 consist, for example, of short angle pieces, one leg of which is connected to the disk 13 and the other leg lies in the direction of rotation of the disc. This latter leg has a rearwardly inclined front edge in order to be taken along or milled off of the goods filled in the storage container, but to prevent them from getting stuck on the milling elements.

In operation, the distributor disk 13 with the milling members 14 mills away the material located in the storage container 11 in layers, which is thrown by the rotation to the outside, where it is caused by the negative pressure generated by the paddle wheel 7 over the ring slot between the distributor disk 13 and the cylinder container 11 the Blow bars 6 is supplied. The hay and straw are ground by these beater bars until they pass through the ring sieve 8 and the paddle wheel 7 and then the outlet 4 can be fed. To prevent the goods from backing up in the storage container during operation 11, its inside is provided with a narrow sheet metal strip 16 in the form of at least one screw thread, which prevents the backlog.
