The typical way of re-aligning a rotary kiln is called hot kiln alignment, and it is best done by professionals. This should ideally be done at least every 1-2 years, to account for tiny shifts over time. However, you should carefully vet candidates for this job. Kiln repair and maintenance is a niche field, and you do not want to trust your ...

AGICO support rollers are solid and wear-resistant, with long service life and simple maintenance. The wear rate of the working surface of the support roller is generally 2 to 4 mm per year, and the normal service life can reach 6 to 10 years. In the daily operation of the rotary kiln, the uneven defects occasionally appearing on the surface of ...
