Sweet smell of success for Chinese company

China's first recyclable calcinator for mica was developed successfully by China Crystal New Material Holdings Co Ltd, cutting the calcining process by 33.3 percent and greatly improving the quality and efficiency of compounding mica.

According to Dai Zhongqiu, a senior executive at China Crystal, traditional calcinators contain a high proportion of iron and impurities, therefore the quality of the compound mica they produce is relatively low, and it usually costs a lot for the post processing of compound mica. In addition, using firebricks, one of the main components of traditional calcinators, is time-consuming, and it is hard to manage damaged firebricks in an environmentally friendly way. These disadvantages seriously restrict the development of the compound mica industry.

"It took us four years to develop the recyclable calcinator. We have overcome a series of difficulties from fundamental materials to process technology. The new product will change the global production mode of compound mica, and will promote the high-quality development of China's compound mica industry," Dai said.
