Oxidation pellet rotary kiln 300 ten thousand tons oxidation pellet production line Metallurgy Machine
1. Introduction
Oxidation pellet rotary kiln is the main production equipment for calcination of pellets in the pelletizing plant. The accuracy of temperature detection at each point in the rotary kiln plays a decisive role in the quality, output, energy consumption, cost and safe operation of the equipment. The rotation of rotary kiln brings many inconvenience to accurately measure the temperature inside rotary kiln. Therefore, choosing accurate, economical and practical temperature measuring system of rotary kiln is an important means to ensure the normal production of rotary kiln.
In 2003, a Φ5×33m oxidized pellet kiln was manufactured to fill the gap in China. In 2005, "world kiln king" Φ 6.58×47.2m pellet kiln was manufactured. Metallurgy Machine
2. Case: The first 3 million ton oxidation pellet production line in China successfully reached the standard and reached production
The first stage production line of Yangzhou Taifu 2×3 million tons oxidized pellets project contracted by Luo Mine successfully reached the standard and reached production.
This project is the first 3 million ton pelletizing production line in China. The smooth production line of the first phase reached the standard and reached the production, which set a new benchmark in the complete pelleting field and laid a foundation for the company to further strengthen the complete pelleting project.
It is estimated that the production capacity of the first phase of the production line reaches 9,600 tons after 24 hours of continuous operation, exceeding the designed capacity of 9,200 tons, which is highly appraised by the owner. In this project, the main equipment of oxidizing pellet production line includes grate 5.2×57 m, rotary kiln 6.4×43 m in diameter, ring cooler 22 m in diameter, disk pelletizer 7.5 m in diameter, rotary drum dryer 4.0×30 m in diameter, 500t/h strong mixer and so on, which fully shows the company's core manufacturing and total package capacity.
