The expanded cabo granulation is to produce one of critical process in the expanded cabo turnary porous granule technology, and the indexs such as filling value, product form and product yield of turnary porous granule are all had crucial influence.
There is following deficiency at least in traditional Granulation Equipments: at first be the restriction that receives blade shapes and structure, when blade impacts expanded cabo, expanded cabo torn pulverizing, the product that obtains is made broken bigger.And turnary porous granule is the grain products that needs certain diameter, and particle diameter just can only be processed as discarded object less than particle and the powder of 1.5mm, has reduced the production yield of product.Next is because to receive blade self shape and structural limitations and blade and blade support be to be fixedly connected; When impacting expanded cabo, blade also expanded cabo is carried out stronger extruding; Cause the offal after the expansion impacting atrophy under the effect, reduced the filling value of turnary porous granule.The 3rd, blade impacts expanded cabo and tears, and expanded cabo plane of disruption fiber is by tear fracture, and the expanded cabo plane of disruption is just irregular, and product form is irregular after the granulation, and the grain type is relatively poor.The 4th, blade only carries out Quenching Treatment, and wearability is relatively poor relatively, and hardness is too high, and blade ruptures easily, and hardness is hanged down easy deformation, wearing and tearing, reduces blade service life.
Summary of the invention
The object of the invention is just in order to solve the deficiency that above-mentioned prior art exists, and a kind of particle shape that changes the expanded cabo turnary porous granule is provided, improves the production yield, improves product filling value, improves the blade paddle type mill shear granulator in service life.
The technical scheme that realizes the object of the invention is following:
The paddle type mill shear granulator, comprise band charging aperture and discharging opening the granulation storehouse, be installed in the granulation storehouse can be around the blade support of central shaft rotation, be installed on the shear-blade on the blade support, the central shaft outer end of blade support is connected with actuating unit;
