Description

Technical Field

[0001] The utility model relates to the technical field of fertilizer processing, in particular to an anti-clogging fertilizer granulator. Background Art

[0002] The granulator is mainly composed of feeding, stirring, granulating, transmission and lubrication systems. A filter screen with special holes is designed on it. It is carefully screened, and its friction filter rod can break the solid particles of the screen. It is widely used in the pharmaceutical, chemical and food industries. The granulator is used for fast granulation and good effect. Fertilizer refers to a type of substance that provides one or more essential nutrients for plants, improves soil properties and increases soil fertility. It is one of the material bases of agricultural production. Fertilizer processed into granules is not only more conducive to plant absorption, but also can prevent the loss of nutrients. However, when the granulator of the prior art processes fertilizer, due to the certain humidity of the fertilizer, it is easy to cause the discharge hole on the granulation plate of the granulator to be blocked and difficult to clear, thereby reducing the granulation efficiency. Moreover, when feeding, the raw materials are often introduced into the interior of the granulator through the upper hopper, and the raw materials put into the upper hopper cannot be intermittently blocked. When too much raw material is put in, the granulator cannot handle it, resulting in blockage of the feed port, thereby reducing the granulation efficiency. Utility Model Content
