Wet-preparation process for mancozeb water dispersible granules

The invention discloses a wet-preparation process for mancozeb water dispersible granules, which aims to solve the technical problems of heavy pollutions and difficult storage, transport and dissolution of agricultural carmazine. The adopted technical scheme is that: the preparation process is realized by a dispersion machine, a grinding machine and a spray granulation and drying tower, and specifically comprises the following steps of: adding crude mancozeb and a filler into a dispersion tank of the dispersion machine, and fully mixing the ingredients to form uniformly-dispersed slurry by using the dispersion machine; feeding the uniformly-dispersed slurry into a grinding hopper of the grinding machine by using a feeding pipeline, and performing grinding by using the grinding machine; and feeding the ground slurry to the spray granulation and drying tower, and performing spray granulation by using granulation spray orifices to form the mancozeb granules. The key of the wet-preparation process is that: the crude mancozeb and the filler are crushed by a wet method, so dust pollutions to the atmosphere are reduced and economic cost is saved.
