Before pelletizing, we need to grind the raw material to small particle which has to be smaller than the hole of the die, which is an important stage in a mature wood pellet mill plans. The particle can be generated through the small hole of the screen with a diameter from 1mm to 10mm. Owning to wide range for the size of the screen in the hammer mill, it can produce the particles in different sizes. For this reason, hammer mill is widely used in pellet plant. But there are some components of hammer mill you may not have a clear idea.
Reversing starter
A reversing starter essentially doubles lifespan of the hammers by allowing them to wear in both directions. This item of equipment is essential to low operating costs.
Magnetic protection
Magnetic protection should be installed above or before the product enters the hammer mill. This can collect any rogue pieces of metal before the product enters the hammer mill.
Air assist system
An air assist system is vital for an efficient production process. Air assist systems draw air into the hammer mill with the product to be ground. Systems are designed to provide reduced pressure on the exit side of the screen, drawing particles through the exit screen holes. Some full circle hammer mills are designed so the screen is in two pieces. It is possible to use a larger hole size on the upward arc of the hammers to further reduce the amount of material on the face of the screen.
