As the inner lining of the rotary kiln, not only the scouring of the hot materials in the kiln, but also the erosion of the dust gas, and the heat insulation performance is also required. After years of painstaking research and development, our company has successfully developed high-strength composite prefabricated bricks. The wear-resistant layer has high strength and corrosion resistance, and the light-layer insulation effect is good, which ensures the improvement of the thermal efficiency in the kiln. And our unique design in brick and masonry styles ensures the overall performance of the entire liner. After the use of a number of pellet plants, active ash, calcined petroleum coke, titanium dioxide and siderite magnetized roasting rotary kiln, received very good results, life expectancy of more than 2 years. For the user to improve economic efficiency, saving maintenance costs, has earn the user's recognition and praise.
