Hammer mill

Particularly effective in the wood and biomass sector, the horizontal hammer mill has been applied to the task of particle size reduction in milling applications.
La Meccanica’s hammer mills are characterized by: heavy duty construction, direct coupling of rotor through an elastic coupling, bidirectional rotation, rotor with dynamic balance, screen that can be manually withdrawn from the side of the mill, temperature sensor PT 100, access door to the grinding chamber equipped with a safety block system.aaaa

Description of the hammer mill:

- Heavy duty construction
- Direct coupling of rotor through an elastic coupling
- Bidirectional rotation
- Rotor with dynamic balance
- Temperature sensor PT 100 monitors bearing temperature
- Access door to the grinding chamber is equipped with a safety block system.
 
Each hammer mill is supplied with:
- Screen
- A set of hammers
- Elastic coupling
- Vibration absorbers.
