Lime production line: optimize resource utilization and promote green industrial upgrading

At the beginning of the 21st century, with the rapid expansion of the steel, chemical and non-ferrous metal industries, the lime industry ushered in a good opportunity for development. Lime, as an indispensable basic material in the national economy, is widely used in metallurgy, building materials, chemical industry, electric power and environmental protection and other fields. In particular, the increasingly stringent environmental protection standards have opened up new markets for flue gas desulfurization and industrial wastewater treatment for lime enterprises, and promoted the innovation and upgrading of industry technology.

Traditional lime production methods, such as ordinary shaft kilns, are gradually eliminated because of their low efficiency and high pollution. It was replaced by mechanized shaft and rotary kilns. Among them, the rotary kiln with its high efficiency, high quality, high automation and environmental protection standards, has become the preferred choice of the steel industry. However, the existing lime kilns generally have the problem of limited applicability of raw materials, resulting in a large number of underutilized small-size limestone resources being wasted.

ZK CORP came into being and launched an innovative lime production line to overcome the limitations of existing technologies and realize the effective use of resources. The production line consists of four key parts: raw material storage and transportation system, limestone calcination system, finished product transportation system and flue gas treatment system.
