Annular Cooler
Annular cooler is main equipment for the pelletizing and sintering process, it is common equipment in this industry. It is widely used for sinter and pellet cooling. There are two main functions: cooling high temperature oxidation pellet which discharged from kiln, to ensure the temperature low enough and satisfy to subsequent process; as the key point of thermal equilibrium for whole system, it recycles quantity of heat which is from high temperature pellet, and it used for previous process thereby reducing the fuel consumption. As per different function or characteristic, there are two types of pellet annular cooler and sinter annular cooler. Our company has all types of annular cooler, and we have capacity to develop and design as per client’s requirement. Our production has many advantages such as simple structure, reliable performance, easy for operation and maintenance etc, and it widely used for metallurgy industry. The new type of annular cooler which develop by our company is more batter sealing, more batter for energy conservation and emission reduction and waste heat recovery.

Rotary Cooler
1.Scope of Application Rotary cooler belongs to rotary cylinder equipment, which is mainly composed of supporting unit, cylinder part, transmission unit, head and tail sealing cover, head and tail sealing unit, etc. The function of rotary cooler is to cool the high-temperature materials produced by the rotary kiln to a certain temperature through the cooler, and then carry out transportation, storage and next treatment. According to different equipment materials, processes and working conditions, it can be divided into air-cooled cooler, water-cooled cooler and air-cooled mixed cooler. 2.Model and Specification Specifications: ? 2.0m×20m~? 4m×50m Volume m3? 63~628 3.Product Introduction NHI has advanced design, manufacturing, installation and operation technology, and can produce various specifications of cooling machines. NHI has mastered key technologies such as sealing, transmission, installation, production and operation, and fault handling.
