Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of hammer heads, in particular to a split hammer head. Background Art
[0002] Crusher generally processes larger pieces of material, and the product size is coarse, usually greater than 8 mm. Its structural feature is that there is a certain gap between the crushing parts, and they do not touch each other. Crusher can be divided into coarse crusher, medium crusher and fine crusher. The hammer head is the crushing component on the crusher, which is installed on the roller shaft of the crusher. The material is crushed by the hammer head. Since the hammer head is a wearing part, it needs to be replaced frequently. The existing hammer head adopts an integrated structure, which is installed on the roller shaft of the crusher as a whole. Therefore, when replacing it, the entire hammer head structure needs to be replaced. The replacement speed is slow, and the front end of the hammer head is generally severely worn when the hammer head is working. Therefore, the replacement cost of replacing the entire hammer head structure is high. Therefore, a split hammer head is proposed to facilitate replacement and save replacement costs.
