Pressure testing machine carton pressure testing machine, pellet pressure testing machine, well cover pressure testing machine, cement pressure testing machine, concrete pressure testing machine! Different models of testing machine for users to choose!

4. 1. The small and uniform particle size of pellets is beneficial to the improvement of gas permeability and uniform distribution of gas flow
2. The cold strength (compression and wear resistance) of pellet is high, which is convenient for transportation, loading, unloading and storage, with less powder
3. The high iron content and high bulk density of pellets are beneficial to increase the effective weight of blast furnace charge column, increase the output and rece the coke ratio
4. Pellet has good recibility< However, the rection expansion rate of pellet is higher than that of sinter, which is not good
in terms of technology, this point can be understood from the following aspects:
1. Sinter needs to add fuel into the burden, while pellet does not, but it needs to be roasted in hot waste gas
2. Bentonite is used as an additive for pelletizing, while flux, usually quicklime, is used instead of additive in sintering
3. Pelletizing proction depends on high temperature roasting, the roasting process can not be directly observed by naked eye, but the sintering fire directly contacts the material and the proction situation is very intuitive
