High efficiency reciprocating grate cooler and control flow grate coolers developed by us has been successfully used in the cement production lines ranging from 300 tpd to 6000 tp day. grate cooler is reliable in adapting to the clinker, throughput fluctuations and adverse working conditions
The high resistance new type control flow trough grates are used with good airflow permeability and cooling features which can effectively remove "red river"
The temperature of the secondary and tertiary air is high, with heat recovery efficiency of the cooler over 70~75%
-The grates are specially heat treated with low loss
-The specific air consumption is less than 2Nm3/kg clinker
-The new type of air girder supply structure with good air tightness and air flow features is used, eliminating the air leaking and scurrying at the hot end grate bed air chamber and uneven clinker cooling.
