Rotary kiln refers to a rotary calcination kiln (commonly known as a rotary kiln), which belongs to the category of building materials and equipment. Rotary kilns can be divided into cement kilns, metallurgical and chemical kilns, and lime kilns according to the different materials they process. Cement kilns are mainly used for calcining cement clinker, and are divided into two categories: dry method cement kilns and wet method cement kilns. Metallurgical and chemical kilns are mainly used for magnetization roasting of poor iron ore in steel plants in the metallurgical industry; Chromium and nickel iron ore oxidation roasting; Refractory material factory roasting high alumina vanadium earth ore and aluminum factory roasting clinker and aluminum hydroxide; Chemical plants roast minerals such as chromium ore sand and chromium ore powder. Lime kiln (also known as active lime kiln) is used to roast active lime and light calcined dolomite used in steel and ferroalloy plants.
Advantages of rotary kiln structure:
1. Technology, production, lime
The rotary kiln produced by Xinxiang Changcheng Machinery adopts a structural and low-pressure vertical preheater, which can improve preheating effect and production efficiency. The quality of the materials produced is very good, making it an ideal energy-saving and environmentally friendly rotary kiln equipment.
2. Energy saving calcination method and calcination mechanism
The furnace body design adopts a fully sealed calcination mechanism, and the refractory insulation layer inside the kiln is made of multi-layer refractory materials, which is mild and good. The designed service life of the refractory insulation layer inside the furnace is more than 5 years. In order to utilize energy, the upper and lower parts of the furnace adopt a heat exchange method, greatly reducing the loss of heat from the upper and lower parts.
3. Using frequency converters for energy-saving operation of equipment
The power used in the production of rotary kilns is controlled and operated by frequency converters, avoiding the phenomenon of large horses pulling small cars and no-load operation, saving an average of over 40% of electrical energy.
4. High production capacity and low heat consumption
The rotary kiln calcination system equipment produced by Henan Hejia adopts domestic and foreign hydraulic blocking wheel devices, metering plunger pumps and speed regulating valves, as well as contact graphite block sealing devices and other domestic technologies through technology, resulting in high output and low energy consumption.
