Description

Technical Field

[0001] The utility model relates to the technical field of grinders of fertilizer production equipment, in particular to a vertical drying grinder for organic fertilizer. Background Art

[0002] The complete set of organic fertilizer production equipment mainly consists of a fertilizer turning machine, a fertilizer crusher, a dynamic batching machine, a fertilizer mixer, a fertilizer granulator, a dryer, a cooler, a drum screening machine, a film coating machine, and an automatic packaging machine. The crusher is a machine that crushes large solid raw materials into the required size and is one of the basic equipment in the organic fertilizer production line.

[0003] For example, Chinese invention publication CN 218459697 U discloses a vertical pulverizer for producing microbial fertilizers. This pulverizer utilizes a first motor, crushing blades, a second motor, and a crushing blade to repeatedly crush the fertilizer. A humidity sensor, controller, and heating wire prevent fertilizer adhesion, achieving efficient pulverization and preventing clumping and adhesion. This also achieves the technical objectives of improving absorption efficiency and eliminating the need for cleaning. However, this invention utilizes two motors, resulting in a complex structure. Furthermore, it lacks a device for separating partially crushed and fully crushed fertilizer lumps. This can easily result in some fertilizer lumps remaining in the processed fertilizer, causing unnecessary complications in subsequent processes.

[0004] For example, Chinese invention publication CN 212189365 U discloses a vertical chain hammer crusher comprising a crusher body, a screening mechanism, a cleaning mechanism, and a crushing chamber. The screening mechanism facilitates the collection of substandard fertilizer blocks for secondary processing, effectively improving product quality. The cleaning mechanism eliminates the need to remove the pulley dust cover when cleaning the belt, facilitating regular cleaning of the belt surface. However, this invention lacks a drying and drying process for the fertilizer blocks, which can easily lead to semi-wet (highly) wet fertilizer blocks adhering to the inner walls of the crushing chamber and related mechanisms.
