Description

Valaic kinetic energy, proportional to. “s of the 1st Maase and iKBaiHp.aiT.y-oracle-pi. Due to the difference between iMacc and forces (clusters that have a place with low moisture of the material, large and small particles go into DIvie relative to each other, ipaiCCiTOH. N (ie between IHIHIMIH increases, the degree of resistance increases). In a static layer, frostness ic will decrease the number of moles of humidity to decrease | s, since the meldium iB particles of the ET01M case are more lighter than IB d (iamy layer).

The lower limit of the flow rate is chosen for users, O0 containing a high percentage (more than 40%) of the concentrate and low-alumina sludge. containing Zyug adanee 20%. To create None of the moisture in granulation and Schicht requires, with an increase in the proportion of the ROLE, concentrate in water less water. The upper limit of the water flow 1 corresponds to the current consumption, the inaccessibility of the MOI to create an optimal 1V-F (NOSBi blend having a low flow rate). the IB concentrate of the ore part and high-alumina aggl.rrudy (SiO2 content (more than 20%). Sinter blend, 1 st. in the ore part 70% 1K) ≈ 1% concentrate and 30% m: ikhaylo1V10koy agluruda, has the optimum. which corresponds to the consumption of 1WHODES iHa 1 t of charge, paBHiOiMy 0.02 m.

In this case, with a change in the humidity of the agglomerate, the slopes of the coupling between the particles are imbued and the material outgrowth changes, as well as the volume of the interstices between the particles that characterize the porosity of the layer. The change in flowability does not cause a change in resistance, since the particles of the charge relative to each other are stationary, and causes a change in the resistance Cal2 between the electrodes of the ler / pair, since the mixture is in a dynamic state here, i.e. dismounts from the taranty tape.
