Description

Technical Field

[0001] The utility model relates to the technical field of pulverizers, in particular to a pulverizer with a blade that is convenient for replacing. Background Art

[0002] With the rapid development of industrial technology, crushers, as important material handling equipment, have been widely used in chemical industry, building materials, medicine, environmental protection and other fields. There are many types of crushers on the market. Most of them use motors to drive the crushing blades to rotate to achieve the crushing operation.

[0003] In order to prevent debris from flying around during the crushing process, the top of the crusher is generally closed, and the crushing blades on most crushers are generally tightly welded to the corresponding shaft body, which has the defect that the crushing blades cannot be replaced or are not easy to replace. After working for a long time, the sharpness of the crushing blades will decrease, and the blades are prone to breakage during the crushing process. At this time, the crushing blades cannot be replaced, which will affect the normal use and crushing effect of the crusher; some crushers are equipped with inspection holes, but the inner diameter of the inspection holes is small, and the space inside the crusher is limited. It is also difficult to replace the blades directly inside the crusher, which brings inconvenience to the user. In view of this, we propose a crusher that is easy to replace the blades.
