Hammer Mills

Fowlerex Hammer Mills are specifically designed for size reduction.

These can be used for size reduction of wood waste, bark, grain, and various other products.

In practice a Fowlerex Hammer Mill has achieved a 3-fold increase in bulk density (35 kg/m3 to 105 kg/m3) on dried Pinus Radiata shavings; however this is dependent on the application and will vary.

The Fowlerex Hammermill consists of hammers positioned about a rotor, spinning at high speed, breaking the shavings up as they pass through the mill.

Due to the regenerative turbulence, the larger particles generally do not pass through the mill until they have been shattered into smaller particles. Different size reduction screens on the outlet can also improve the reduction as required.

Installation
Normally the hammermill is fed via a conveying duct, hopper, screw or belt conveyor with a centrifugal fan extracting the milled shavings away, minimising any possible blockages. In certain circumstances, the hammermill can be directly installed under a suitable cyclone.

Fowlerex is happy to assist with a system design suitable to your requirements.

Benefits
Saves on storage requirements (because of increased density).
Reduced handling equipment and costs (smaller feed screws required).
Improved consistency for boiler fuel (gives more controlled combustion).
