## Abstract

A crushing drying device includes an object-to-be-treated supply port from which an object is supplied into a main body, a crushing portion for crushing the object by hammers rotated on a drive shaft, and a classifying portion having a space for circulating the object to be treated at a position away from the crushing portion, the crushing portion has a dry gas supply port from which the heated air is supplied in a predetermined direction along an inner surface of the device main body, and the classifying portion has discharge portions from which the crushed object is discharged together with the heated air, and deviation plates for changing a flow of the object transferred to the classifying portion, so that the crushing drying device is one machine.

## Claims

### Claim 1

A crushing drying device, comprising: an object-to-be-treated supply port from which an object to be treated is supplied into a device main body;
a crushing portion for crushing the object to be treated supplied from the object-to-be-treated supply port by a crushing element rotated on a drive shaft; and
a classifying portion having a space for circulating the object to be treated crushed in the crushing portion at a position away from the crushing portion, wherein
the crushing portion has a dry gas supply port from which a dry gas is supplied in a predetermined direction along an inner surface of the device main body, and
the classifying portion has a discharge portion from which the crushed object to be treated is discharged together with the dry gas supplied from the crushing portion, and a deviation portion for changing a flow of the object to be treated transferred to the classifying portion together with the dry gas.

### Claim 2 (depends on 1)

The crushing drying device according to claim 1, wherein the deviation portion changes the flow of the object to be treated circulated in the classifying portion toward circulation center in the classifying portion.

### Claim 3 (depends on 1)

The crushing drying device according to claim 1, wherein the deviation portion has a support portion on the upstream side in the flow direction of the object to be treated, and includes a variable deviation plate capable of changing a downstream end toward the circulation center in the classifying portion centering on the support portion.

### Claim 4 (depends on 1)

The crushing drying device according to claim 1, wherein the deviation portion has a predetermined gap providing communication between the classifying portion and an exterior,
a dry gas supply portion is provided in the exterior of the classifying portion, and
the dry gas is supplied to the classifying portion from the dry gas supply portion via the gap.

### Claim 5 (depends on 1)

The crushing drying device according to claim 1, having a guide portion for guiding the dry gas supplied from the dry gas supply port toward the classifying portion between the crushing portion and the classifying portion, wherein
the guide portion has a slope surface for guiding the object to be treated returned from the classifying portion to the crushing portion to the object-to-be-treated input side of the crushing element.

### Claim 6 (depends on 1)

The crushing drying device according to claim 1, wherein the classifying portion includes the discharge portion in the circulation center part, and
the discharge portion has a discharge pipe portion protruding toward the outer side from a side surface of the device main body, and a discharge port from which the crushed and dried object to be treated is discharged from an outer end of the discharge pipe portion together with the dry gas.

### Claim 7 (depends on 1)

The crushing drying device according to claim 1, wherein the classifying portion includes the discharge portion in the circulation center part, and
the discharge portion has a discharge pipe portion protruding toward the inner side of the classifying portion from a side surface of the device main body by a predetermined amount, and a discharge port from which the crushed and dried object to be treated is discharged from an outer end of the discharge pipe portion together with the dry gas.

### Claim 8 (depends on 1)

The crushing drying device according to claim 1, wherein the crushing portion has an object-to-be-treated supply port provided in an axial center part of the drive shaft on which the crushing element is provided, and a rectifying plate for suppressing the object to be treated supplied from the object-to-be-treated supply port from being moved in the axial direction of the drive shaft.

### Claim 9 (depends on 1)

The crushing drying device according to claim 1, wherein the object-to-be-treated supply port is provided with a supplier for supplying the crushed object to the crushing portion by a fixed amount.
