Zinc oxide rotary kiln from HANDA is a main equipment to calcine and smelt materials for zinc oxide, which has been widely used in cement industry, metallurgy field, chemical engineering, paper manufacturing and other fields. The accretion of rotary kiln cannot only affect the quality of zinc oxide, damage the refractory material in kiln, shorten the lifespan of rotary kiln, but also increasing the labor intensity. Therefore, it is important and necessary to know how to prevent the kiln from accretion and enhance the furnace heat efficiency of zinc oxide rotary kiln.

As the leading professional rotary kiln developer and manufacturer, HANDA has launched a series precaution against the accretion of zinc oxide rotary kiln. The precaution includes controlling from the resource raw materials, setting sundry separation screen at material receiving place and arrange staffs for goods sorting if sundries are more, optimizing the charging gear, water adding device and scraper device, improving the sieving system and optimizing the heating.

For enhancing the furnace heat efficiency of zinc oxide rotary kiln, HANDA suggests follow the below approaches.
1)Choose the rational furnace type and hearth structure to ensure the optimum combustion regime and the minimum heat loss.
2)Improve the combustion technology and combustion apparatus, which is beneficial to control and adjust air excess coefficient and enhance combustion efficiency, realizing the minimum heat loss caused by imperfect combustion and exhaust fume.
3)Adopt superior refractory material to reduce the heat loss from furnace heat storage, heat dissipation and heat absorption of water-cooled components.
4)Promote waste heat recovery and utilization.
5)Strengthen the furnace heating management and control, raising the operation level.
6)Employ the advanced thermal technology and process.
