As shown in Fig. 1 and Table 1, for minimizing the particulate emissions, there are five sets of precipitators that are used to clean flue gas from the anthracite crusher, the raw material blender, the no. 1–no. 4 windbox groups of the sinter strand, the screener (including sinter cake crusher, hot and cold screener), and the circular cooler ...
It is divided into two kinds: single tooth roller crusher and double tooth roller crusher. The single-tooth roll crusher is installed at the tail of the sintering machine to break the hot sinter; The double-toothed roller crusher is used to break the cold sinter and is the main equipment of the whole grain system in the sinter plant.
Crush the sinter in a roll crusher: Collect and purify gas from hot sinter crusher and sinter transfer: Collect gas from the stack corresponding to the hot sinter crushing stage. The emissions are abated by the evacuation of dust and subsequent purification of collected gas: Screen hot sinter
At the end of the grate the hot sinter breaks into lumps of up to half a meter in size and falls onto a rotary crusher. The crushed hot sinter may still contain pieces of 300 mm size when it issieved at about 5mm mesh size. Specimens of hot sinter were taken from this sieve just before being charged onto the rotary sinter cooler.
