Insulation for cement rotary kiln should be a lightweight, heat-resistant material used for cement kilns, filters to separate solids from gases or liquids, sound-absorbing to reduce noise, backing material for refractory linings to protect against high temperature environments. Kiln lining thermal solutions should also resist chemicals, provide fire protection, and offer structural support where needed.
Microporous thermal insulation board composed of fumed silica, opacifier and fiber, can meet all above requirements perfectly. Rotary kiln insulating materials have some restrictions when we are selecting suitable materials. When used in the cement industry for rotary kiln, microporous board is regarded to be the most advanced insulation material with lowest thermal conductivity compared with other traditional insulators to help save space and improve energy efficiency.
