Audited Supplier Alumina Ceramic rollers are hi-tech advanced ceramic products made with patented cool isostatic pressing technique and over 50 years
of professional manufacturing experience. It is a kind of refractory material in roller kiln, as the role of bearing and transmission in the furnace. The service temperature can up to 1400C.
With the development and production of ceramic, roller kiln is widely used in building sanitary ceramics, daily porcelain and specialty ceramics. The requirements of refractory material used in furnace are continuous improvement, especially for strength and high temperature mechanical properties of roller presented updated requirements.
Alumina ceramic rollers is the development trend for ceramic rollers, because they fully meet the various needs of ceramic tile production, with the other advantages which other ceramic roller cannot be of.
Features and Advantage
1. Low thermal expansion and low porosity.
2. High bending strength and hard hardness: Good wear ability
3. Perfect toughness and optimized microstructure
4. Outstanding thermal shock resistance
5. Corrosion resistance: No sour alkali salt can corrode it.
6. Excellent high temperature performance
7. Good heat resistance change performance
8. Totally enclosed: Both ends equipped with plastic enclosed ring, only oil won't leak, making the roller axle revolve under the situation of long-time totally enclosed.
9. Long service time: 2-3times longer than the steel roller and can reduce the wearing of belt.
10. Great profitable efficiency: Can lower the comprehensive cost of belt conveyer and the repairing time.
11. Ceramic surface: Form an oxidized membrane, won't connect with and react with any materials. The trough roller can clean the belt.
Application
Alumina ceramic rollers are widely used in roller kilns for firing wall tile, floor tile, table ware, sitall tile, magnetic materials and electronic ceramic,etc.
