## Abstract

A vibratory mill principally for the treatment of cement and fly ash, which mill has a grinding chamber (1) with a wall (6, 7) at each of the two ends of the chamber, which mill includes an inlet (2) for material that is to be treated and an outlet (3) at the rear wall (7) of the grinding chamber (1), at the lower part of the grinding chamber, and a first wall (5) inside the chamber at the end at which the outlet (3) is located, which wall (5) is provided with one or several openings (8) at its upper part, which openings allow passage of material that has been sufficiently ground from the grinding chamber to the outlet (3). The inlet (2) is located in the lower part of the grinding chamber (1) at the wall (6) that is opposite to the location of the outlet.

## Claims

### Claim 1

A vibratory mill principally for the treatment of cement and fly ash, which mill has a grinding chamber (1) with a wall (6, 7) at each of the two ends of the chamber, which mill comprises an inlet (2) for material that is to be treated and an outlet (3) at the rear wall (7) of the grinding chamber (1), at the lower part of the grinding chamber, and a first wall (5) inside the chamber at the end at which the outlet (3) is located, which wall (5) is provided with one or several openings (8) at its upper part, which openings allow passage of material that has been sufficiently ground from the grinding chamber to the outlet (3), characterised in that the inlet (2) is located in the lower part of the grinding chamber (1) at the wall (6) that is opposite to the location of the outlet.

### Claim 2 (depends on 1)

The vibratory mill according to claim 1, characterised in that a second wall (9) is present inside the grinding chamber, which second wall is located at the inlet (2) and is provided with an opening (10) at its lower part for the introduction of material that is to be ground.

### Claim 3 (depends on 1)

The vibratory mill according to claim 1, characterised in that the said opening (10) in the second wall (9) is located at a distance from the bottom of the grinding chamber that is 10-30% of the radius of the grinding chamber.

### Claim 4 (depends on 1)

The vibratory mill according to claim 1, characterised in that said opening or openings (8) in the said first wall (5) has or have a total surface area that is 1-60% of the surface area of the first wall (5).

### Claim 5 (depends on 2)

The vibratory mill according to claim 2, characterised in that the said opening (10) in the second wall (9) is located at a distance from the bottom of the grinding chamber that is 10-30% of the radius of the grinding chamber.

### Claim 6 (depends on 2)

The vibratory mill according to claim 2, characterised in that said opening or openings (8) in the said first wall (5) has or have a total surface area that is 1-60% of the surface area of the first wall (5).

### Claim 7 (depends on 3)
