Chengdu Leejun Industrial Co., Ltd. is the leading enterprise that manufactures grinding roller press in China, of which main products include cement clinker/raw material roller press, mining roller press and powder separator (O-sepa). 

Leejun has obtained breakthrough in the aspect of abrasive resistance, and become the first enterprise in China that successfully applied roller press in cement raw material and mine powder. Market share of Leejun’s roller press for cement clinker reached 33% and 48% in 2009 and 2010 respectively, holding leading position in the industry. 

Comparably, mine roller press is still in the initial stage of development. In the future, demand of roller press for iron ore and non-ferrous metal will be relatively large. It is expected that the newly added output of iron ore and non-ferrous metal will generate roller press demand valued RMB8.3 billion and RMB28.2 billion during 2011-2015; meanwhile, demand for roller press caused by technological improvement will achieve RMB9.2 billion and RMB33.8 billion separately. 

In December 2011, Leejun publicly issued 41 million shares and raised funds of RMB744 million, for the construction of roller press industrialization base. When the project reaches full production, it is estimated that the newly added roller press capacity will amount to 181 sets, contributing sales revenue of RMB1.55 billion.
