Cement rotary kiln co-processing solid waste technology is mature technology which used in developed country & area and has over 30 years’ experience. Develop cement kiln co-processing solid waste technology can relief the huge environmental press caused by insufficient solid waste treating capacity. It is significant to improve the solid waste treating waste capacity in emergency and which is the demand for controlling environmental risk & promoting circle economic development.

Great wall developed solid waste co-processing rotary kiln, via inlet variety limit, harmful element feeding control, smoke pollution treating, feeding point selection, cement product quality and so on. Main points are to control pollution in the whole process and proposed relevant control measures. Now we have the specification of 100T/D, which total input amount is RMB35, 000,000. Later based on customers’ requirements, we can develop 300T/D and 500T/D equipment.

At present Chinese cement industry co-process the solid waste of industrial slag such as fly ash, sulfate slag, blast furnace slag, etc. with low substitution. Using cement rotary kiln to co-process dangerous waste, domestic sludge, household waste, polluted soil and industrial waste just is starting. The publishing of《cement kiln co-processing solid waste pollution control standard》configured standard is significant to specify cement kiln co-processing solid waste, carry out environmental supervision, improve enterprise management level and promote healthy development of the industry. The government published a series of documents to promote the cement kiln co-processing solid waste technology, so it is estimated to be rapidly developed.
