Description

Technical Field

[0001] The invention relates to the technical field of granulation equipment, in particular to a drying extrusion granulation equipment for paraformaldehyde. Background Art

[0002] In order to control the size of the particles, the current rotary granulator is equipped with an annular knife holder outside the rotating screen, and a plurality of scrapers that fit the screen are fixed on the knife holder. This can control the particle size and prevent sticky particles from sticking to the particles. However, there are still some problems: First, when the material is very sticky, it is easy for the material to adhere to the edge of the scraper and gradually accumulate into large pieces. Once large pieces are formed, they will not meet the particle size requirements whether they are manually cleaned or fall off naturally.
