Which grinding mill is better for coal injection
This will depend on the extent of wet and dry of your material. If the level of wet and dry of your material is more than 15%,it's better to be equipped with drying equipment .

Pulverized coal injection or 'PCI' technology is just one area where Claudius Peters brings together several of its 'Techniks' to offer a comprehensive turnkey system. Combining unparalleled knowledge of grinding and pneumatic conveying over long distances and silo storage expertise with precise measuring and coal dosing technology, PCI systems bring together several of Claudius Peters individual technologies to provide a comprehensive turnkey solution, which in the steel industry has become a technology in its own right.In this instance PCI technology is used in the steel making process to replace up to 50% of the coke charge used for smelting, with the far cheaper fuel, coal, offering a lower cost, more efficient and more environmentally friendly system.

Coal injection – dense phase conveying
State-of-the-art blast furnaces feature pulverized coal injection (PCI) systems. The injection of up to 200 kg of coal per ton of hot metal replaces nearly the same amount of coke and, therefore, reduces production cost of the blast furnace iron.

New developments such as the Oxi-Coal-System, two lances per tuyere, pre-heating of the coal to be injected, and a high conveying gas load result in increased injection rates of pulverized coal. Plugging is avoided with the injection system developed by KÜTTNER, and abrasion of the piping is minimal.

The processing of the raw coal to injection quality is achieved in a coal grinding and drying plant. The hot stove waste gas, or the combustion of blast furnace top gas, can be employed as heat source for drying. The milling takes place in either a vertical mill or a hammer mill, depending on the required grain size. The pulverized coal is separated in a bag filter.

Kuttner has delivered plants for hard coal and blends with volatiles between 8-42 Vol% and Hardgrove indices of 40-95 ºHGI.
