Hammer Mills

Hammer mills can be custom-designed according to your operation and required specifications and will vary according to the raw material/product used. The construction of each mill is of the highest quality, ensuring durability and strength to withstand general vibration. Hammer mills are available in a General/Basic and Blower Option. General/Basic- the milled product passes through the mill and straight into a bag. “Blower” – the milled product passes through the mill and is moved via a blower into a cyclone where it is bagged off from a two-way bagging attachment. Typical hammer mill designs operate at 2800rpm with various screen sizes available.
