Pellets plants are normally integrated with the iron ore beneficiation plants. In case they are not integrated then concentrated iron ore in slurry form is usually pumped to the pellet plant by slurry pipelines. Pellets plants based on rich iron ore fines are rare and not very economical. The entire pelletizing process can be divided into two ...
The following chapter will provide the basis to understand and apply pellet mill automation. The many parameters that govern the operation of a pellet mill will be discussed first. After that, the instrumentation required to electrically sense and monitor the process variables will be introduced.
Pellet Feed. Pelleting is a process in which mixed feed in powder form is converted into pellets by mechanical compression in combination with moisture and heat. Process is achieved by a set of rolls and die of suitable hole size and shape. As the die & roll rotates, the product passes through the nip of roll & die and pressed into the die ...
Feed material for the DR process is either sized iron ore of size ranging from 10 mm to 30 mm or iron ore pellets of size ranging from 8 mm to 20 mm produced in an iron ore pellet plant. The gas based process uses a shaft furnace for the reduction reaction. The coal based process uses any one of the four types of reactors for the …
Although direct reduction processes can operate with pellets having an iron content of 65% or lower, typical of blast furnace (BF)-grade pellets, the preferred feed for a DR plant has an iron content of 67% or greater. The principal sources of DR-grade pellets are located in South America, Canada, Sweden, Bahrain and Iran (TABLE I).
