Product Description

Description:
We are deliverying New Energy Saving Products DDR50FH for our Europe Client; this low thermal conductivity anti-chipping bricks are new low density refractory bricks developed for cement rotary kiln preheating zone. To serve in severe conditions, LZR DDR series bricks have excellent mechanical strength, good resistance to thermal shock, and are highly resistant to chemical attack from vilatil alkalis and some slags. We manufacture and design DDR bricks with special raw material to meet the requirements of a wide variety of service conditions. With excellent performance, our products have been widely used in the domestic and foreign cement projects.

Feature:
Excellent resistance to chemical corrosion.
Great thermal mechanical stress.
Low thermal conductivity Reduce the load on the furnace deposits and the mechanical stress.
Resistance to thermal shock

Application: 
preheating/calcining zone of cement rotary kiln.
