# Multi-layer Combined Sealing of Composite Flexible Integrated Sealing Structure
Triple-layer stacking consisting of high-temperature resistant fish-scale plates, carbon-silicon-aluminum thermal insulation composite boards and flexible fireproof cotton adopts a combination of hard and soft materials to completely block the gap between the cylinder and the fixed smoke chamber, eliminating the long-standing problems of ash leakage and air infiltration.
# Adaptable to Radial and Axial Displacement of Kiln Body
Rotary kilns are subject to vertical swing, forward-backward displacement and eccentric deformation during operation. The flexible buffer structure can automatically fit the kiln body as it deforms without scraping the cylinder or cracking to cause material leakage.
# Greatly Reduces Coal Consumption and Saves Energy
It blocks cold external air from flowing backward into the kiln to stabilize firing temperature and cut coal combustion consumption. Meanwhile, it prevents heat loss caused by outward leakage of high-temperature hot air, bringing considerable energy-saving benefits for cement plants with long-term operation.
# Customized High-Temperature Resistant Designs for Different Scenarios
The kiln head version withstands a maximum temperature of 1200°C for the high-temperature flame zone; the kiln tail version resists flue gas at 850°C and acid dust corrosion. Materials are optimized separately for the two working conditions to double the service life.
# Low Dust Emission for Easy Environmental Compliance Inspection
It prevents yellow smoke emission at the kiln head and dust overflow at the kiln tail, eliminating flying ash across the plant area. It reduces the load on bag dust collectors and the frequency of dust removal consumable replacement, ensuring full environmental compliance with no risk of rectification orders.
# Simple Installation and Retrofit
On-site retrofits of existing kilns are available without extensive steel frame cutting via modular assembly for direct replacement of old kiln seals. Professional technicians can be dispatched to conduct on-site dimensional surveying to produce customized complete sealing sets.
# Corrosion and Thermal Shock Resistant with Slow Aging and Low Breakage Risk
It resists corrosion from alkaline dust and sulfide flue gas inside the kiln, and remains crack-free and non-powdery under repeated hot-cold alternations. Its service life is 2 to 3 times longer than traditional asbestos seals and single-layer steel plate seals.
# Reduces Equipment Wear and Operation & Maintenance Costs
Cold air infiltration intensifies thermal shock to the cylinder and refractory bricks. Intact seals protect kiln linings, extend the service cycle of refractory materials and reduce frequent kiln shutdowns for maintenance.
