【正文】 GR is designed through solid modeling and virtual assemble， meanwhile， the structure rationality is tested by checking the static intervention among parts of HPGR. Stating from engineering application， its enforcement not only shortens the exploratory period of the new product， enhances its design quality， and reduces its research cost， but also lays a technical base for furthering the development progress of industrialized and serial equipments， hastens the equipments’ application in metal mining for crushing hard ironstone.
