Ceramic Fiber Blanket for Chile Cement Plant: Applications, Sizes and Insulation Solutions

Cement plants operate continuously under high-temperature conditions. Rotary kilns, preheaters, calciners, kiln hoods and hot air ducts all require reliable thermal insulation.

Ceramic fiber blanket is a lightweight and flexible insulation blanket widely used in cement plants because it provides excellent thermal insulation while being easy to cut, install and replace.

For Chile cement plant projects, Mindelun Materials supplies ceramic fiber blankets in different temperatures, densities, thicknesses and roll sizes according to the actual application.

Where Is Ceramic Fiber Blanket Used in a Cement Plant?

The most important point when selecting a refractory blanket is to match the product specification with the actual equipment and installation location.

1. Rotary Kiln Insulation

The rotary kiln is one of the most important applications for high-temperature insulation.

Ceramic fiber blanket can be installed as a backup insulation layer behind refractory lining or around selected high-temperature areas of the kiln system.

Recommended specification:

• Temperature: 1260°C or higher grade according to working conditions

• Density: 128 kg/m³

• Thickness: 25 mm or 50 mm

• Width: 610 mm

• Roll length: 7.2 m or customized

For projects requiring stronger mechanical performance, a higher-density ceramic fiber blanket can be considered.

2. Kiln Hood Insulation

The kiln hood is exposed to high temperatures and requires effective insulation to reduce heat transfer to the steel structure.

Recommended ceramic fiber blanket:

• Density: 128 kg/m³

• Thickness: 25–50 mm

• Width: 610 mm

• Roll length: 7.2 m or customized

The blanket can be cut into suitable sections according to the shape of the kiln hood.

3. Preheater Insulation

The preheater system contains several high-temperature components. Ceramic fiber insulation can be used around equipment shells, inspection areas, access doors and other locations requiring lightweight insulation.

Recommended specification:

• Temperature grade: 1260°C

• Density: 96–128 kg/m³

• Thickness: 25–50 mm

• Width: 610 mm

• Customized length available

For areas with higher mechanical requirements, 128 kg/m³ ceramic fiber blanket is generally a practical choice.

4. Calciner Insulation

The calciner operates at elevated temperatures and requires effective thermal insulation.

A ceramic fiber blanket can be installed around the external surface of the equipment or used as part of a multilayer refractory insulation system.

Recommended specification:

• Density: 128 kg/m³

• Thickness: 25–50 mm

• Width: 610 mm

• Roll length: 7.2 m or customized

For higher-temperature zones, high-purity or high-alumina ceramic fiber products can be selected.

5. Hot Air Duct Insulation

Hot air ducts and exhaust ducts are another important application for an insulation blanket.

The flexibility of ceramic fiber blanket makes it suitable for cylindrical pipes, ducts and irregular surfaces.

Recommended specification:

• Density: 96–128 kg/m³

• Thickness: 25–50 mm

• Width: 610 mm

• Customized roll length

For large-diameter ducts, several layers can be installed to achieve the required insulation thickness.

6. Tertiary Air Duct Insulation

The tertiary air duct carries high-temperature air and therefore requires good thermal insulation.

For this application, 128 kg/m³ ceramic fiber blanket with a thickness of 25–50 mm can be considered depending on the operating temperature and required external surface temperature.

7. Burner and High-Temperature Equipment

Ceramic fiber blanket can also be used around burner systems, access doors, expansion areas and other high-temperature components.

Typical sizes include:

• 10 mm

• 20 mm

• 25 mm

• 50 mm

The thickness should be selected according to the available installation space and required thermal performance.

Common Ceramic Fiber Blanket Sizes for Cement Plants

For international cement plant projects, the following sizes are commonly convenient for installation:

Other widths and roll lengths can be produced according to the customer's installation requirements.

How to Choose 25 mm or 50 mm Ceramic Fiber Blanket?

25 mm ceramic fiber blanket is suitable when installation space is limited or when it is used together with other insulation or refractory layers.

50 mm ceramic fiber blanket is suitable when greater insulation thickness is required and sufficient installation space is available.

For many cement plant applications, 128 kg/m³, 25–50 mm ceramic fiber blanket provides a good balance between insulation performance, mechanical strength and installation convenience.

Why 128 kg/m³ Ceramic Fiber Blanket?

For cement plant applications, density is an important consideration.

A 128 kg/m³ ceramic fiber blanket provides better mechanical strength and handling performance than very low-density blanket. It is particularly suitable for applications where the insulation material needs to withstand installation, vibration and handling.

For less demanding areas, 96 kg/m³ can also be considered.
