Absorbed foreign advanced technique of powder granulator ,improved and heightened on the basis of foreign technique ,this dry-type granulator is developed by our factory. it has more reasonable and compact structure, simply technological processes, easy operation and better performance .Powder materials can be made into even granules customer needs without adding any bonding agent when they run through the machine. As density of granules are larger ,no any afterward process is needed so as to reduce technological process ,reduce granulation cost and powder pollution and improve labor technological process ,reduce granulation cost and powder pollution and improve labor environment as well .
