Double-shaft mixing machine specially designed for new construction of dry powder mortar special technological requirements of a new generation of hybrid machine for new building materials. Increasing the transmission power and tube wall thickness, stirring shovel can be adjusted, the service life is longer, more evenly mixed. For solid-solid (powder and powder) mix, spray liquid mix (body), for mixed operation in zero gravity, is the ideal mix of dry mortar production line equipment. Powder--liquid), for mixed operation in zero gravity, is the ideal mix of dry mortar production line equipment.
