Improve hammermill reliability under demanding conditions
Hammermills operate under demanding conditions where even small issues can quickly escalate into major problems. Continuous vibration, heavy loads, and harsh operating environments put significant stress on both mechanical and electrical components. As a result, operators often face challenges such as unplanned downtime caused by bearing wear and failures linked to vibration, imbalance, and misalignment.
In addition, excessive or fluctuating loads can cause motors and gearboxes to overheat, shortening equipment lifespan and increasing maintenance needs. Power quality issues, including harmonics and poor power factor, further impact performance by reducing overall plant efficiency, increasing energy costs, and in some cases leading to utility penalties.
ABB offers a solution with Ultra Low Harmonics (ULH) drives which allow, with a single device, to bring the cos phi to 1, deleting all the reactive power and avoiding penalties from the energy supplier. the harmonic content is reduced to values lower than 5% causing an economic benefit on the entire chain of components from the media cabin to the motor.
