Roller repairing in cement


Roller press roller in the application of wear-resistant surfacing roller press is China's late 1980s imported from abroad a high-pressure grinding equipment, with high efficiency and energy saving features, especially for cement clinker grinding , But also for limestone, blast furnace slag, lime sandstone, coal, gypsum, quartz sand and iron ore grinding and other good effect. After continuous improvement and improvement, this equipment has been widely used in the cement industry, and gradually expanded to large-scale development.



China is currently the largest roller press production, wear-resistant roller surfacing level also represents the international advanced level. Zhengzhou Machinery Research Institute designed and developed Z D1, Z D2, Z D3 and Z D310 series of hardfacing flux-cored welding wire, respectively, the roller surfacing wear resistant materials in the transition layer, the buffer layer, the hard surface and Wear pattern layer welding materials. Through the reasonable collocation of these kinds of materials, the hardness gradient of the roller surface is formed, which effectively ensures the service life of the roller surface. The wide application of this kind of welding material shows that the service life of the roller body exceeds that of the imported material by the wear-resistant surfacing protection of the roller body surface, reaching more than 8000h, basically meeting the needs of cement production. Through continuous scientific research and innovation, the company has now achieved the roll-mill roll body new roll manufacturing, the roller surface off-line for overhaul repair and production on-site repair of the on-line roll repair.
