Description

TECHNICAL FIELD

[0001] The application relates to the technical field of a granulator, in particular to a soil remediation solidifying agent granulator and a granulation method. BACKGROUND

[0002] A granulator is a general equipment for processing powder, liquid, block and other materials into uniform particles, and the core function is to realize material forming through physical or chemical methods, and the granulator is suitable for the needs of solidifying agents, feed, fertilizers, medicines and other industries. As a kind of granulator, the ring die granulator is widely used in the granulation processing of solidifying agents. The moving pressure roller cooperates with the vertical ring die to extrude the material, so that the material is extruded from the die hole of the ring die to form particles.

[0003] However, the existing ring die granulator has poor material concentration effect when processing solidifying agents. After the material enters the middle part of the ring die, it will be dispersed in a large area in the middle part of the ring die, and will be excessively deposited at the bottom of the equipment, which is easy to cause the upper die hole to be idle due to the too thin material layer or even unable to be covered. In the granulation process, the upper and lower die holes are mainly used for granulation, and the use rate of the upper and lower die holes is too different, which is easy to cause excessive use and wear of the lower die hole, and cause the ring die to be damaged in advance.
