Effects Of Not Using Refractories In Cement Plant
FOB Reference Price:
Get Latest Price
In the cement industry, many plants use materials that cause or contribute to the build-up of dust and particulates on the lining surface. This is exacerbated by the presence of alkali vapours and salts. When these particulates build up in areas that restrict airflow, it can have extremely undesirable effects and even cause plant shutdown.
