Hammermills | Hammer Mills | High Capacity Particle Sizing
wsm hammermills feature a large diameter hammer circle and throat widths from 20" to 60". Rotor operation at 1800 rpm provides high tip speed milling action for superior product sizing. The nearly full circle sizing screens maximize production in fine-grind applications, delivering higher capacities and consistent product sizing.
Hammermill tip speed adjustment alters particle size ...
Hammermill tip speed adjustment alters particle size without downtime. Particle size range for a hammermill screen size can be adjusted through manipulation of the hammer tip speed, which is made possible by the use of motor variable frequency drives. The hammermill is a cost-effective method of reducing particle sizes of grains for feeding.

corn, reducing the hammer mill screen size from 9.6 mm to 1.2 mm resulted in a linear reduction in geometric standard deviation (Wondra et al., 1995b; Wondra et al., 1995c). When hammer mill screen size was plotted against geometric standard deviation, each 1 mm reduction in milling screen size resulted in a 0.09 reduction in
Hammer mill: parameters that affects grinding
When deciding the fan size, we should keep in mind that a hammer mill has a resistance of about 10-15 m bar. A reduction in the air flow rate leads to a reduction in mill capacity, finer product, higher specific energy consumption, greater heating during milling, greater wear, greater dust formation.
