Refractory for Cement Rotary Kiln

The environments of transition zone, burning zone and cooling zone in cement rotary kiln are severe due to high temperature from burning clinker and erosion of K,Na,Cl,S.

The upsize of rotary kiln and usage in waste disposal make the condition of using refractories even harsher.

LMM Yotai group developed MgO-Cr203 series, MgO-Al203 Spinel series and non-chrome series bricks for cement rotary Kin, which have achieved remarkable results.

We occupy top shares in Japan refractory market, and have expanded greatly in China market as well.
