In the production process, the material is required to have a certain viscosity, some raw materials are relatively loose after fermentation, and it is not easy to granulate, so it is necessary to add some water or adhesive to increase the viscosity of the material. Organic fertilizer equipment disc granulator and rotary drum granulator use the pellet method to granulate, in the process of granulation will add water or adhesive to ensure that the material can be smoothly granulated. The new type of gear granulator uses wet granulation, and the material after fermentation can be directly granulated without the operation of other processes. The double roller press granulator is produced by a non-drying process at room temperature, which is suitable for the granulation of materials with low viscosity or low water content. Organic fertilizer processing equipment is with the development of agriculture, technological progress, diverse needs and continuous renewal of organic fertilizer granulation equipment, among which, because the equipment itself after years of development, equipment design to achieve organic combination, production and research and development has been continuous progress, equipment has been better and more comprehensive development. It is understood that the organic fertilizer processing equipment produced by the plant has never stopped the pace of progress, and has been leading the industry for many years.
