Highland Refractory successfully completed the supply of 15 metric tons of JM28 mullite insulating bricks for a ceramic manufacturing factory in Uzbekistan. The project aimed to upgrade the insulation lining of the ceramic kiln, improving thermal efficiency, operational stability, and overall energy performance.
As a professional refractory manufacturer with extensive export experience, Highland Refractory provided not only qualified products but also technical support throughout material selection, production, and delivery.
The customer is a ceramic factory in Uzbekistan specializing in the continuous production of ceramic products. Their kilns operate under long firing cycles and stable high-temperature conditions, where heat loss, temperature uniformity, and insulation reliability directly affect product quality and production costs.
Before this project, the customer faced several challenges:
High heat loss from kiln walls and roof
Increasing energy consumption
Aging insulation materials with reduced performance
The need for a reliable, long-term insulation solution
The client was looking for a refractory insulation material that could maintain stable performance under continuous kiln operation while helping reduce fuel consumption.
After evaluating different insulation materials, the customer chose JM28 mullite insulating bricks as the optimal solution for their ceramic kiln application.
JM28 bricks offer a well-balanced combination of thermal insulation performance and mechanical strength, making them suitable for ceramic kilns that operate at medium-to-high temperatures over long periods.
Key reasons for selecting JM28 mullite insulating bricks included:
Reliable performance under continuous high-temperature operation
Low thermal conductivity to reduce heat loss
Stable structure and dimensional accuracy
Proven application in ceramic kiln insulation systems
Compared with lower-grade insulating bricks, JM28 provides better durability. Compared with higher-grade materials, it offers a more cost-effective solution for this specific kiln temperature range.
The JM28 mullite insulating bricks supplied for this project were manufactured under strict quality control standards.
Typical technical properties include:
Classification Temperature: 1500°C
Bulk Density: Approx. 0.8–0.9 g/cm³
Cold Crushing Strength: ≥ 2.0 MPa
Thermal Conductivity (at 400°C): Low, optimized for insulation
Standard Sizes: Customized sizes available based on kiln design
These properties ensure stable insulation performance, reduced thermal loss, and sufficient mechanical strength for kiln lining applications.
In this project, JM28 mullite insulating bricks were mainly used as the insulation lining layer of the ceramic kiln. They were installed behind the hot-face refractory layer to minimize heat loss through the kiln structure.
The lightweight nature of JM28 bricks helped:
Reduce the overall load on the kiln structure
Improve installation efficiency
Shorten construction time
Highland Refractory also provided technical guidance on installation and material handling to ensure proper performance after commissioning.
After installation and commissioning, the ceramic factory reported positive results:
Noticeable reduction in heat loss from the kiln
Improved temperature stability during firing cycles
Lower fuel consumption compared with the previous lining system
More stable kiln operation and reduced maintenance frequency
The customer was satisfied with both the product quality and the technical support provided throughout the project.
For this project, a total of 15 tons of JM28 mullite insulating bricks were supplied.
Packaging: Moisture-proof cartons and palletized packaging
Transportation: Export shipment arranged for Uzbekistan
Quality Control: Pre-shipment inspection ensured consistent quality
Delivery: Completed on schedule according to the project timeline
The smooth logistics process helped the customer avoid delays and ensured timely kiln refurbishment.
The customer selected Highland Refractory as their supplier based on several key factors:
Extensive experience in insulating refractory materials
Stable product quality and consistent technical parameters
Customizable solutions for ceramic kiln applications
Reliable export packaging and international logistics support
Responsive technical and commercial communication
This project further strengthened Highland Refractory’s presence in the Central Asian market.
The successful supply of 15 tons of JM28 mullite insulating bricks to a ceramic factory in Uzbekistan demonstrates Highland Refractory’s capability to provide reliable insulation solutions for ceramic kiln applications.
By selecting the right insulation material and working closely with an experienced supplier, the customer achieved improved energy efficiency, stable kiln operation, and long-term performance benefits.
