History
1995 | The original company of AOKEROLA GROUP, Zibo Yuanda Co. was founded. |
1998 | Incorporating with Spanish Refractory Institute, Weifang Aokerola Fine Cermaics Corporation was founded. |
1999 | Invented the isostatic medium alumina ball, and achieved the industrialization. |
2000 | Started the production of high alumina ball in the Weifang Plant |
2001 | Successfully developed the OK-Y686 iso-static ball press and won the national patent. |
2002 | Participated in making the National Quality Standard of Ceramic Roller in China. |
2003 | Successfully developed the low wear loss and low cost grinding media"Super Wear-Resistant King" |
2004 | Zibo Aokerola Ceramic Technology Co. Was founded. |
2005 | Zibo Plant started the production of medium alumina lining brick. And at the same time, Aokerola started the internationalization. |
2006 | Shandong Aokerola Technological Material Co., Ltd was founded, and successfully developed the global longest, full-automatic, intelligent medium alumina ball production line by high temperature roller kiln. |
2007 | Successfully built the unique biggest shuttle kiln for roller production, and introduced the cutting edge roller production technology from Germany inthe end of 2007. |
2008 | Started the production of high alumina ceramic by the High Temperature Roller Kiln, and achieved the Non-Quality-Difference production system, Which makes AOKEROLA become the first company which uses high temperature roller kiln to produce high alumina ceramic. |
2010 | The Fourth new high alumina ceramic production line is under construction and the Fifth new roller project is going to start. |
2011 | The new advanced low ware loss medium & high alumina grinding balls were brought into batch production.the medium alumina ball has been successfully replaced by the new developed high and medium alumina ball. |
