This fertilizer granulator series is a new type of fertilizer equipment product. It uses wet granulation method to directly generate spherical particles from high humidity materials after composting fermentation. No adhesive is added to the granulation process of the new type organic fertilizer granulator. New type organic fertilizer granulator makes use of the principle that tiny particles are mosaic each other because of being hit. The high humidity material after fermentation is directly made into spherical particles, and there is no need to add binder in the granulation process.
