What is the cost of ceramic fiber cotton filling for insulation materials in the cement industry?

What is the cost of filling ceramic fiber cotton for insulation in the cement industry? Ceramic fiber cotton insulation materials on the market are charged by weight, volume, and small pieces, with significant price differences for products of different specifications. Rosewool Insulation Refractory Co.,Ltd. is committed to the research and production of thermal insulation materials. We have applied various solutions for ceramic fiber blankets in various industries, with rich case studies, source factories, and extremely high cost-effectiveness.

We all know that the main application areas of ceramic fiber blankets in the cement industry include: rotary kiln hood, tertiary air duct, preheater, grate cooler, pipeline expansion joint, refractory castable backing filling, and maintenance port filling. However, the filling types generally use ceramic fiber cotton/loose cotton, spray blown cotton, and filling blanket crushed cotton, which are divided into ordinary type, high alumina type, and PLUS reinforced type.

Suggestions for selecting ceramic fiber cotton for filling in the cement industry:

1. Confirm the operating temperature: There are significant temperature differences in different parts of the cement plant, so the expansion joint of the preheater (about 900 ℃) can be selected as the 1260 ℃ standard type; It is recommended to choose high alumina type for the decomposition furnace and kiln hood (about 1000-1100 ℃); Zirconium containing materials must be selected for hot areas of rotary kilns (>1200 ℃).
2. Loose cotton vs blanket/board:
Loose cotton: suitable for filling irregular gaps and small spaces, with a relatively low price
Blanket/board: suitable for large-area flat insulation, with higher construction efficiency
3. Select the form according to the purpose:
Expansion joint filling: Choose loose cotton, with a fluffy texture that is easy to fill and compact
Gap sealing: Choose loose cotton or compressed packing cotton, and adjust the filling amount according to the size of the gap
Filling of irregular parts: choose soft loose cotton, easy to fit complex shapes

The temperature resistance of ceramic fiber cotton directly determines its price. The working temperature of different parts of the cement industry (such as kiln head, kiln tail, pipelines, etc.) varies, and different grades of fiber cotton need to be matched:
Regular/Standard Type (with a temperature resistance of about 1050 ℃ -1260 ℃): The price is relatively affordable, usually around three to four thousand yuan/kg.
High purity type/high aluminum type/zirconium containing type (temperature resistance up to 1260-1430 ℃): Due to the addition of high cost raw materials such as alumina or zirconia, the high temperature resistance and shrinkage resistance are stronger, and the price is usually around five to six thousand per kilogram, or even higher.
