Technical Field

[0001] The utility model relates to the technical field of pulverizers, in particular to a pulverizer metal removing device. Background Art

[0002] A pulverizer is a machine that crushes large-sized solid raw materials into required sizes. The pulverizer consists of coarse crushing, fine crushing, wind conveying and other devices. The purpose of the pulverizer is achieved by shearing the material through the mutual engagement of the crushing rollers. It is usually used to crush recycled waste items.

[0003] During the use of the current pulverizer, the material to be pulverized is added to the inside of the pulverizer through the feed port. When the pulverizer is started, the two pulverizing rollers inside the pulverizer rotate in opposite directions, and the pulverizing rollers roll the objects into the inside, and the meshing parts of the two pulverizing rollers cut the objects into pieces, thereby achieving the pulverizing effect. The pulverized objects are discharged from the discharge port, completing the entire pulverizing process. For example, a pulverizing mechanism with the application number "201520923876.3" includes a shell, a pulverizing shaft and multiple groups of pulverizing leaf groups. The shell is provided with a feed pipe and a discharge pipe connected to the inside thereof. The pulverizing shaft and the multiple groups of pulverizing leaf groups are all arranged inside the shell, one end of the pulverizing shaft passes through the shell, the multiple groups of pulverizing leaf groups are all connected to the pulverizing shaft, and the multiple groups of pulverizing leaf groups are arranged at intervals, each group of pulverizing leaf groups includes four pulverizing leaves, one end of the four pulverizing leaves are all connected to the pulverizing shaft, and the four pulverizing leaves together form a "cross" structure, and the "cross" structure of the multiple groups of pulverizing leaf groups is divergent in the axial direction of the pulverizing shaft.
