As the name implies, vertical lime kiln is a vertical kiln used to burn lime. The modern new technology vertical lime kiln produced by Zhengkuang Machinery is a modern lime kiln with environmental protection, energy saving functions, and a high degree of mechanization and automation. Because it uses modern technology, it can make full use of cheap energy, especially the gases that originally polluted the environment (such as converter gas, blast furnace gas, calcium carbide furnace tail gas, etc.) as the main energy source, turning waste into treasure.
Lime shaft kiln, in contrast to lime rotary kiln, is a cylindrical equipment with full steel structure, which uses the principle of heat exchange between the downward movement of material and the upward movement of hot gas to burn lime. Our company can design and manufacture lime shaft kiln equipment with a production capacity of 50-400 t/d, which is stable and reliable in operation, environmentally friendly and energy-saving, with a high degree of automation, and can use various low calorific value converter gas, blast furnace gas, and calcium carbide furnace tail gas as fuel.
Types of lime kilns
In addition to lime shaft kilns, our company can also produce lime rotary kiln.
Application fields
Suitable for metallurgy, building materials, calcium carbide, nano calcium carbonate, aerated concrete, sugar making and other industries.
Our Advantages
1. The kiln has great flexibility in operation, and can be adjusted from 60-100% to achieve stable production;
2. Applicable fuels are solid fuels such as coke and anthracite;
3. Low heat consumption and reasonable use of heat energy. The secondary high-temperature air preheated by cooling lime directly participates in combustion;
4. The vertical kiln adopts micro-negative pressure operation (kiln top) to make the airflow in the kiln evenly distributed, which is conducive to the calcination of lime
ZK Corp can provide rotary kiln, experimental rotary kiln, lime shaft kiln and related accessories.Welcome to contact us! Whatspp: 0086 17398960706 Email: inczk@zkcorp.com
