A conical mill is a machine for reducing the particle size of material, to create a consistent and uniform finished product.  The conical mill benefits from low noise, minimal heat, reduced dust, higher throughput and a more uniform finished particle size.

Material is fed into the conical mill via the in-feed chute, this can either be via gravity feed or by vacuum.  Once the material has passed through the in-feed chute, it the reaches a rotating impeller which forces the material through the holes in the screen.

With a conical mill it is possible to alter the particle size, particle shape and other characteristics, simply by changing the screen.  For example, the hole size will determine the particle size, so a larger hole will produce a larger particle.  Once the material has passed through the screen, the finished product exits through the milling chamber into a receptacle beneath.

Hanningfield offer the conical mill in a range of different sizes.  From table-top sized mills, to full-scale production models, a conical mill can be used to satisfy a wide range of requirements, most notably in the pharmaceutical, food, chemical and cosmetic industries.

Typical applications for a conical mill include:

• Reclaiming broken tablets, biscuits or other material
• Sizing wet granulated particles before drying
• Sizing dry granulated particles before tabletting
• Deagglomerating dried fruits or other clumped material
