Grain die and manufacturing method thereof and granulator

Abstract

The invention relates to a grain die and a manufacturing method thereof and a granulator. The grain die is provided with die holes; and a protuberance inclined toward the two sides of the die holes along the adjacent parts of the die holes is arranged between adjacent die holes. The granulator with the grain die puts the material to be pressed into the grain die, and the grain die is rolled by a compression roller; and due to the protuberance between adjacent die holes, inclined toward the two sides of the die holes along the adjacent parts, the material at the protuberance can move toward the two sides of the die holes along the protuberance in the rolling process, thus the rolling dead angle at the protuberance is eliminated, the running resistance of the compression roller is reduced, the wasted power consumption is reduced, and the output is increased. The grain die performs processing by use of a turning mode, and the mode is simple and easy to implement.

Description

Technical field [0001] The invention relates to feed or biomass fuel processing equipment, in particular to a compression mold body of feed or biomass fuel compression molding equipment, a manufacturing method and a pressing machine. Background technique [0002] In a current feed or biomass fuel processing equipment, a driving device drives a pressure roller to rotate in a pellet mold, and the pellet mold is provided with a die hole. Once pelletized feed or biomass fuel is squeezed out of the die hole by the pressing roller in the pellet die, it forms a large, densely shaped solid material. [0003] In the working process of this kind of processing equipment, the outer edges of the two adjacent die holes and the outer edges of the pressure roller form an approximately triangular area. The material rolled by the pressure roller in this area forms a rolling dead angle, resulting in excessive running resistance of the pressure roller , Resulting in useless power consumption, serious...
