How long do hammers last in a hammer mill?

The service life of hammers in a hammer mill varies from a few weeks to a few months and, in some situations, years. The lifespan depends on several factors:

• Hard and tough raw material has a negative impact on the life of the hammers.
• High contamination such as pebbles or grit lead to a shorter lifetime of the hammers.
• In the case of fine grinding (sieve plates with small perforations), the life of the hammers is shorter.
• Speed: with higher speed, the life of the hammers is shorter.
• Specific capacity: if a higher capacity passes through the hammer mill, the life of the hammers will be shorter.
