Lime Shaft Kiln

A lime shaft kiln, as opposed to a rotary kiln, is an all-steel, upright, cylindrical unit. It utilizes the principle of heat exchange between the weight of the material descending and the rising hot gases to burn lime. Our company can design and manufacture lime shaft kilns with production capacities ranging from 50 to 400 tons/day. These kilns offer stable and reliable operation, are environmentally friendly and energy-efficient, and feature a high degree of automation. They can utilize various low-calorific-value converter gases, blast furnace gases, and calcium carbide furnace exhaust as fuel.

  • Applications

    Suitable for industries such as metallurgy, building materials, calcium carbide, nano-calcium carbonate, aerated concrete, and sugar production.

    Product Introduction

    A lime shaft kiln, as the name suggests, is a vertical kiln used for burning lime. Zhengkuang Machinery's new technology lime shaft kilns are modern lime kilns that are environmentally friendly, energy-efficient, and highly mechanized and automated. Because it utilizes modern technology, it can fully utilize inexpensive energy, particularly gases that were previously polluting (such as converter gas, blast furnace gas, and calcium carbide furnace exhaust) as its primary energy source, transforming waste into valuable resources.

    Highlights
    ● High kiln operation flexibility: The kiln can be adjusted from 60% to 100% to maintain stable production.
    ● Suitable for solid fuels such as coke and anthracite.
    ● Low heat consumption and efficient use of heat energy: preheated secondary high-temperature air directly participates in combustion after cooling the lime.
    ● The vertical kiln utilizes a slight negative pressure (at the kiln roof) to ensure uniform airflow distribution within the kiln, facilitating lime calcination.

    Operating Principle

    As the name suggests, a vertical lime kiln is a vertical kiln used for calcining lime. Zhengkuang Machinery's new technology vertical lime kiln is a modern lime kiln that is environmentally friendly, energy-saving, and highly mechanized and automated. Because it adopts modern technology, it can make full use of cheap energy, especially the gases that were originally polluting the environment (such as converter gas, blast furnace gas, calcium carbide furnace exhaust, etc.) as the main energy source, turning waste into treasure.
