JCF Mill
Impact Mill

The JCF series of machines can be combined to give maximum flexibility and modularity for diverse industries, and, to this end, as well as the simple mechanical construction of machinery, we provide an overall system which complements and completes the excellent mechanics with the very latest electronic systems, user friendly and simple to interface

Construction specifications

The JCF series grinding mill is a new combined system, consisting of a horizontal grinding unit and a dynamic classifier, in a single compact machine.

The maximum particle size for entry of materials is 15 mm, and the degree of fineness of the end product ranges from 8 to 150 μ.

This system is universally suitable for most products with a maximum hardness of around 3.5 Mohs.

It can also be adapted for materials with a hardness of 7 Mohs if constructed with suitably hard-wearing materials.

The machine can be opened easily for checking, cleaning and maintenance, as it is fitted with a pneumatic mechanism which allows the grinding and classification chamber to be opened.

Operational principle

The product to be milled is introduced into the grinding chamber from above, via a screw feed with variable capacity, and then by star valves which insert the product directly into the centre of the impact chamber.

Here the particles smash against each other and against the grinding parts; for a more efficient grinding action, the material is subjected to collision, friction and cutting in the space between the grinding mechanism and the toothed lining of the chamber.

The milled material is conveyed via an extraction fan to the ultra-fine classifier, adjustable by rotation speed, passing through the selected sieve.

By passing through the selection sieve, the material which has not yet reached the desired fineness is sent back into the chamber for a further cycle of grinding, while the product which is sucked into the transport tube is exactly the correct fineness, without waste or loss of material.
