The company has a strong production capacity of parts, a large operating area in the factory, and an external processing base, which has a large on-site construction capacity. We have successively manufactured a number of large cement kilns, pellet sintering kilns, and large converters for relatively large cement production enterprises across the country, and ensured the coaxiality of the trunnion through user site assembly welding. The final accuracy exceeded the requirements of the drawings and filled the domestic gap.
