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.
