The C. S. Bell multipurpose cast iron grinder is also referred to as a burr mill.
A hammermill is an invaluable tool when processing seed. It is used to break up the shell or pod, liberating the seeds from the pods. This improves the planting process but separating seeds and improving seed to soil contact.
The seed is not damaged because the hammers are not circulating in unison. They are alternating to allow seeds and debris (aka chaff) to move through the screen holes without damage.
You can change the screen and change the speed to fit the size of each seed. For example, if you want a very fine product use a high speed and a small hole size for the screen.
This is a unit we rebuilt for a customer in the past. Please contact us for current availability.
