Abstract: Due to existing problems about low productivity and high energy consumption per ton of vertical circular moulding equipment,the thesis applied TRIZ theory for innovating design of vertical ring die briquetting machine. Determining the system contradictions for vertical circular moulding equipment addressed engineering parameters,and then found the principles of the invention for solving the problem through Altshuller contradictions matrix table. Module was designed to be independent and removable using the invention principles,on the module surface mixed powder coating, module was changed to asymmetrical form. There was 4.3 ° deviation between centerline axis of ring die and location hole,single module improved to double module. The productivity was 2 519 kg/h,the energy consumption per ton was 25.86 k Wh/t, the product density produced by the upper mould and lower mould were 1.13 g/cm3 and 1.22 g/cm3, respectively. These data can be the theoretical basis for improvement of productivity about vertical circular mould briquetting machine.
