When selecting a baler you need to review the full selection of
materials the you want to bale, the physical size and density of the
material and the amount of material that you need to bale. This
information will help set up the criteria for the proper baler for your
application. Balers are typically rated by through-put (tonnes per hour
capacity) and bale chamber size. For instance, if you want to bale a
high volume of cardboard you would need a wide mouth baler with enough
displacement "under load" to keep up with your volume. If you want to
bale paper trim fed from an air handling system, you would only require
a less expensive narrow chamber horizontal baler that has ample
displacement under load to keep up with your production.
