Crusher

Abstract

A crusher capable of stably crushing various information media, such as paper, magnetic tape recording media including cassette tapes, optical recording media, and substrates, and having excellent maintainability In the crusher, hammer members (29) radially extending from a rotating shaft (45) and rotating with the rotation of the rotating shaft (45) is received in a casing (21). The casing (21) has an upper loading opening (22) for loading an object to be crushed and also has a lower discharge opening (23) for discharging the crushed object. Fixed blades (47) are arranged in the casing (21), on the outer diameter side of the hammer members (29), and the object is crushed by the hammer members (29) and the fixed blades (47) when the hammer members (29) are rotated. In the casing (21) is a guide path (20) for guiding the object to a crushing chamber (26) in which the object loaded from the upper loading opening (22) is crushed by the hammer members (29) and the fixed blades (47). A guide body (75) for lifting the object to be crushed to the crushing chamber (26) side is provided on the downstream side of the guide path (20).

Description

technical field [0001] The present invention relates to a crusher, and more particularly to a crusher capable of crushing various products such as paper, cassette tapes, and other magnetic tape recording media, optical recording media, and substrates. . Background technique [0002] As for the pulverizer, there is a pulverizer including a casing (casing) and a pulverizing unit, the casing has an upper inlet for pulverized materials to be put in and a lower discharge port for pulverized materials to be discharged, and the pulverized unit is equipped with In the crushing chamber in the casing (Japanese Patent Laid-Open No. 8-117634 and Japanese Patent Laid-Open No. 2001-153149). [0003] That is to say, the pulverizer disclosed in Japanese Patent Laying-Open Publication No. 8-117634 etc., such as Figure 17 As shown, a discharge plate 5 having a plurality of discharge holes 4 is disposed at the discharge port 3 at the lower part of the casing 1 , and a crushing chamber 6 is f...

AI Technical Summary

Problems solved by technology

In this case, the hammer member 9 does not come into contact with the flakes, and the object to be crushed cannot be crushed by cooperation of the hammer member 9 and the fixed blade 10.

[0006] Moreover, as long as the hammer member 9 and the fixed blade 10 are used for a long time, damage or the like will occur, so maintenance or replacement is required.

However, the fixed blade 10 is installed on the inner surface of the crushing chamber 6, and it is difficult to perform maintenance and replacement operations.

In addition, the hammer member 9 is installed on the rotating circular plate. Although it can be detached from the rotating circular plate, since the hammer member 9 is arranged in the crushing chamber 6, the workability of installation and removal is not good.
