Compression roller assembly jig and compression roller assembly method in dry granulation device

Abstract

The invention provides a compression roller assembly clamping tool in a dry-type granulation device, wherein the clamping tool does not need to be directly held by a worker for supporting a compression roller and is easy to installed on a rotating shaft. The clamping tool is characterized in that the clamping tool is provided with a cylindrical guide part which is inserted in a through hole disposed at the center of the compression roller, is also disposed at the tail end of a rotating shaft which enables the compression roller to rotate and is provided with a tail end part shrinking to be conical; a fixed platform which enables the compression roller to be fixed and not to be able to roll; a height position adjusting mechanism which can achieve the lifting of the fixed platform; and a press-in part which presses an end face of the compression roller to insert the guide part into the through hole of the compression roller.

Description

technical field [0001] The present invention relates to an effective technology applied to a dry granulator for producing products by compressing and molding powders and granules used in the production of metal raw materials, solid fuels, fertilizers, resins, pharmaceuticals, and foods. Background technique [0002] Conventionally, a dry granulation method in which dry powder or grain is compression-molded by a pair of compression rolls is known as a method of granulating powder or grain to produce a metal raw material, a solid fuel, or the like. In the dry granulation method, a powder or granule body to be processed is supplied between a pair of compression rolls. [0003] As a dry granulation apparatus for performing granulation by such a dry granulation method, there is, for example, an apparatus described in JP-A-9-192896. In this dry granulation device, when changing the shape of the granulated material, it is necessary to remove a pair of compression rollers and insta...

AI Technical Summary

Problems solved by technology

[0005] However, since the compression roller is very heavy (approximately 20kg), the work of holding it in a horizontal state and slowly inserting it into the rotating shaft is heavy physical labor, which places a heavy burden on the workers.

In addition, during installation, there is a risk of injury due to the drop of the compression roller

In addition, since the installation work requires a certain amount of experience, there is a problem that the work efficiency of less experienced workers is poor and it takes time.
