JCF Series Hammer Mill
Equipment Specifications
The JCF series hammer mill is a new concept in air
classified milling, utilizing a horizontal rotor disc and liner
with separate classifier, complete with a dosing and air
transport system, all in a single compact machine.
The degree of fineness of the end product ranges between
8 and 150µm starting with a maximum material inlet
particle size of 15 mm and a maximum hardness of around
4 Mohs, but can be adapted for materials with a hardness
of 7 Mohs with specific anti-wear materials.
The mill housing can be easily opened with the built-in pneumatic cylinder for inspection, cleaning and maintenance.
Operating Principle
The milled material is conveyed via an extraction fan to
the high-efficiency dynamic classifier. In the classifier, the
oversize material is sent back into the mill chamber and
subjected to an additional milling cycle. Only the product
with the correct fineness is allowed into the transport
tube, resulting in high milling efficiency.
This arrangement avoids overheating of milled particles
that could destroy their physical characteristics
The product is dosed with a weigh feeder and fed onto the
rotor disc with a rotary valve. Here the particles smash
against each other and against the milling mechanism; to
maximize the efficiency of the grinding action, the material
is subjected to collision, friction and cutting in the space
between the hammer plates on the rotor disc and the mill
liner.

* Data Reference: Calcium Carbonate
A flexible and modular filtration system can be fitted
downstream of the mill, making it possible for a variety of
dosing arrangements or injection points to be integrated
using a single mill.
