Product Description
Pusher Slab Kiln for Face Brick and Tile Production
Pusher kilns, also known as pusher furnaces or pusher-type tunnel kilns, are continuous heating sintering equipment designed for efficient industrial processing. These systems utilize hydraulic pushers to transport green bodies through the kiln at consistent time intervals while maintaining precise temperature control through regulated hot air flow.
Kiln Classification and Applications
Pusher kilns are available in various configurations to suit different manufacturing requirements:
- Push Types: Single-push and double-push configurations
- Movement Direction: Reverse and co-directional push options
- Automation Level: Fully automatic and semi-automatic operation
- Sintering Atmosphere: Oxidizing, neutral, reducing environments
Primary applications include sintering ceramics, magnetic materials, electronic ceramics, structural ceramics, chemical materials, and electronic components.
Key Features and Benefits
- Precise temperature control for consistent product quality
- Simple operation with automated hydraulic propulsion
- Low energy consumption with efficient heating systems
- Wide application range across multiple industries
- Robust construction with high-performance materials
Structural Design and Working Principle
The pusher-type kiln employs an automatically controlled hydraulic propulsion system that pushes materials into the kiln at constant intervals and discharges fired products. Fuel combustion at the kiln bottom generates hot air flow, which is directed by pushers to circulate within the furnace for optimal temperature distribution.
Modern designs incorporate hybrid heating methods, combining gas combustion preheating with electric secondary heating for enhanced temperature precision and energy efficiency.
Construction Materials and Components
Advanced Material Selection: The kiln features mortise-and-tenon structural connections for dimensional stability, with furnace lining using low corundum materials and sliding tracks constructed from wear-resistant dense sintered alumina 98 corundum.
Insulation systems typically incorporate multiple layers including Morgan 1400 type mullite bricks, high-quality lightweight insulating bricks, and imported alumina fiber products for optimal thermal efficiency.

Energy Efficiency Features
Modern pusher kilns incorporate advanced energy-saving technologies including gas-electric hybrid heating systems and cooling waste heat recycling. These systems utilize air cooling channels, collection hoods, and pipelines to recover waste heat from the cooling zone, providing preheated air for de-bonding and heating zones to significantly reduce energy consumption.
