Cement Industry


METHERM® MIP(Microporous Insulatiuon Panel) used for cement industry(rotary kiln, preheater, cyclone, calciner, tertiary air duct, grate cooler, cement grinding mill).

Benefits: Huge energy cost savings and increased product output.

Please refer to the following practical case:

China United Cement Corporation(CUCC) Case

Tertiary air duct 800-1000℃ 164mm Refractory brick + 50mm  METHERM® MIP 108℃ 58.3℃ 50℃ 814 W/m2

Benefits:

1. Energy consumption: the area of METHERM® MIP used: 268x20=5360 ㎡, and the average energy consumption of 1 ㎡ is saved by 600W; Daily energy consumption: 5360㎡x0.6KWx24h=77184KW·h; Energy saving in 6 months: 77184x180 ≈ 14 million kWh;

2.Capacity expansion: 5000 tons to 5500 tons project, greatly increasing the daily cement output.
