As the machines that break heavily abrasive sinter into suitably-sized pieces to feed the blast furnace, sinter crushers are exposed to extreme wear. Being hot, hard and abrasive, sinter is a challenging material to handle. Wear is most strongly experienced in two main areas: the crusher bars and the teeth on the rotor.
The moisture content of return sinter is controlled to within 2 – 3 % in the cooling drum as will be explained later. In the mixing drum, the moisture content of the mix is controlled to about 4 – 5 % which is very important for keeping good permeability of the feed mix to the sinter machine.
