The utility model discloses a disc granulator which comprises a rack and a
granulation disc arranged in the rack, an environment-friendly particle storage
assembly and a
powder storage
assembly which are used for feeding materials into the
granulation disc are arranged above the rack, and the rack is further provided with a spraying
assembly used for conveying binders to the
granulation disc. According to the disc granulator provided by the utility model, chemicals are supplied into the granulation disc through the particle storage assembly and the
powder storage assembly, so that
continuous feeding can be realized, and meanwhile, the spraying assembly is used for conveying a binder to the granulation disc, so that the heat generated by friction is reduced, the potential safety
hazard is reduced, and the production efficiency is improved. Meanwhile, due to the addition of the binding agent, the binding between the external
medicine and the particles is better, the number of the external
medicine particles processed at a time is larger, the
processing quality is better, and therefore the
processing efficiency and the quality after
processing are improved.
