China’s oxidation pellet technologies has developed rapidly. Far more than ten oxidation pellet factories have been constructed to offer substantial-quality pellets for blast furnace ironmaking, which is the long term growth direction of the metal business. The development of a huge-scale oxidation pellet plant addresses a fairly small region, which can properly lessen the investment decision sum of unit products, significantly lessen the power consumption of device products, and hence reduce product costs. Due to the large stage of technologies and equipment of oxidation pellets, it can significantly boost labor efficiency and enhance and safeguard the atmosphere. Pelletizing gear largely consists of: rotary dryer, disk feeder, disk pelletizer, chain grate heater, rotary kiln, ring cooler, lubricating mill, mixing device, coal mill and other total products.
The rotary kiln for pellets in the iron and metal market is primarily composed of rotary element, supporting part, transmission device, kiln head go over, kiln head & kiln tail seal, and combustion system. Kiln mouth guard plate and kiln tail substance return spoon adopt block casting, straightforward to set up, with large warmth resistance, corrosion resistance and put on resistance. The cooling air is handed via the kiln head chilly air jacket, which can evenly cool the kiln head barrel and the kiln mouth guard plate, producing it far more safe and reputable. The kiln head protect adopts a large quantity approach, and the kiln door framework is break up to make the air circulation a lot more secure. The kiln head and kiln tail seals adopt radial friction labyrinth and fish scale double seal varieties, with simple construction and easy upkeep. The combustion unit adopts a swirling four-channel pulverized coal burner with an oil injection ignition system.
