Embodiment Construction

[0022] Figure 1 to Figure 3 A first embodiment of a hammer for a crusher is shown.

[0023] figure 1 A plan view of a vertical crusher is shown in which the drive shaft 3a of the rotor 3 extends perpendicular to the plane of the drawing. Discs 3 b are arranged superimposed on the drive shaft of the rotor, each disc having an opening for mounting a rotating pin 6 . Each of the one or more hammers 4 is suspended on a rotating pin between two discs, optionally using spacer rings. A corresponding arrangement can also be used in crushers in which the drive shaft of the rotor is arranged horizontally.

[0024] An anvil 2 fixedly mounted on a frame 1 cooperates with a hammer head 5 of a hammer 4 during operation. like image 3 As shown, a gap 10 is formed between the anvil 2 and the striker 5 . This gap 10 increases as the striker 5 wears. This gap 10 is related to the fineness of the crushed material. When the hammer is new, the insert is mounted such that during operation ...

Abstract

The invention relates to a crusher with a stationary anvil and a rotating hammer. In this type of machine, when the hammer head wears, it is always necessary to replace the entire hammer if a uniform quality of the crushed material is to be maintained. This is highly cost intensive. Therefore, the present invention proposes a new hammer with an insert with a cylindrical eccentrically drilled or eccentrically elongated hole for receiving the rotary pin of the crusher. This insert has cheeks of different thickness at its two ends, so that by turning the insert 180° in the hammer, the distance between the hammer head and the anvil can be changed. When the hammer head wears too much, the insert can be removed and reinstalled by turning it 180°. Therefore, the gap between the anvil and the hammer head can be kept constant.

Description

technical field [0001] The present invention relates to a hammer iron for a crusher with a stationary anvil, a crushing machine with such a hammer, and a method for operating such a crusher. Background technique [0002] To crush scrap metal or other mixed materials, today's industry already has its disposal crushers, such as hammer mills and crushers. These machines are configured such that an iron hammer (hereinafter also referred to as hammer) is pivotally mounted on a rotor by means of a rotating pin arrangement, and as the rotor rotates, the centrifugal force created by the rotation forces the hammer radially outwards towards a stationary anvil, stationary An anvil is fixedly connected to the frame. The fineness of the crushed material is determined by the gap formed between the anvil and the hammer belt. During this process, care must be taken to ensure that the distance between the anvil and the hammer head (ie, the part of the hammer protruding farthest) does not d...
