An industrial test work was performed to analyse the effect of applying a lower ball load and a finer ball size distribution in the second compartment of a KHD Humboldt Wedag ® ball mill on grinding and classification performance of a hybrid high pressure grinding roll (HPGR)/multi-compartment ball mill cement grinding circuit. Mass balance of the circuit was done by …

As the particle size increases, the difference in particle morphology between ball-milled and vertical-roller-milled slag powders decreases. At the particle grades of 10–20 and 30–40 μm, the morphologies of the slag powders produced by the two types of milling tend to be the same.

Answer (1 of 3): As different ball mill machines grind different sizes, ball mills generally produce p100 size. According to how the material is discharged, ball mills can be divided into overfall and grate types. And they have different properties and advantages. There are many types of …

5. Lower initial cost. The initial construction cost, running cost and maintenance cost of the vertical mill are only 70%~80% of the ball mill equipment. 6. The particle size of the grinding material is large, which can reach 3%-5% of the diameter of the grinding roller. The large-scale grinding allows the material to have a large particle size.

Figure 6 – Particle size distributions from ball mill and vertical mill circuits. Since the automatic sampling system from concentrator II takes samples only from the combined streams on the regrinding circuit, a series of manual sampling campaigns were conducted along the year of 2012 to make this study possible. Figure 7 shows the results.

of the particle size. Thanks to the integrated separator (classifier) the grounded material is separated after each passage. In comparison to a ball mill (with external separator), the separation is sharper. Therefore the particle size distribution (PSD) of the cement has the tendency to be narrow ( high n' according RRSB). This
