Continuous powder processing equipment

Abstract

To provide a continuous powder processing device which enables crushing of powder to be performed efficiently.SOLUTION: A continuous powder processing device performs mixing and crushing of powder and includes: a cylindrical vessel extending in a lateral direction; a rotary shaft disposed in the cylindrical vessel; blades which are attached to the rotary shaft and send the powder from an inlet side opening of the cylindrical vessel to an outlet side opening while mixing and crushing the powder; and a disc attached to the rotary shaft. At an outer peripheral portion of the disc, a number of protrusions protruding to the outer side in a radial direction are formed side by side in a circumferential direction.SELECTED DRAWING: Figure 1

Claims

1. A continuous powder processing apparatus for mixing and crushing powders, A cylindrical container extending horizontally, A rotating shaft is placed inside the cylindrical container, Multiple blades attached to the rotating shaft, which mix and crush the powder as it is sent from the inlet opening to the outlet opening of the cylindrical container, A disc attached to the aforementioned rotating shaft, A continuous powder processing apparatus, wherein the outer circumference of the aforementioned disc has numerous protrusions arranged in the circumferential direction, projecting radially outward.

2. The cylindrical container rotates around its central axis. The central axis of the rotating shaft is located below the central axis of the cylindrical container. The continuous powder processing device further includes a non-rotating partition plate positioned in a gap space formed in the upper part of the cylindrical container, The continuous powder processing apparatus according to claim 1, wherein the partition plate is arranged such that a gap is formed between it and the disc.

3. The continuous powder processing apparatus according to claim 2, wherein, when viewed from the axial direction of the cylindrical container, the upper edge of the partition plate extends near the inner circumferential surface of the cylindrical container and along the inner circumferential surface, and the lower edge extends near the outer circumferential portion of the disc and along the outer circumferential portion.

4. The continuous powder processing apparatus according to claim 2 or 3, wherein the outer diameter of the disc and the outer diameter of the rotational trajectory of the tip of the blade are substantially the same.

5. The continuous powder processing apparatus according to any one of claims 2 to 4, wherein the disc and the partition plate are spaced apart in the axial direction.

6. The continuous powder processing apparatus according to any one of claims 1 to 5, wherein the disc is positioned in a region closer to the outlet opening than to the axial center of the cylindrical container.
