摘要： The present disclosure discloses a double-material grinder for grinding materials comprising a housing and a grinding component. The housing comprises a first housing and a second housing removably attached to each other to form a closed cavity. The first housing comprises a vertical baffle. The grinding component comprises a first grinding unit arranged in the first chamber and a second grinding unit arranged in the second chamber. A blanking gap of the first grinding unit corresponds to the first blanking hole. A blanking gap of the second grinding unit corresponds to the second blanking hole. The second housing comprises a driving unit to drive the first grinding unit and the second grinding unit. The mouth for adding materials is open and substantially larger than those of other two-material grinders so that replenishing of materials becomes easier and mixture of different materials is completely prevented.
