High-Performance Cone Milling
The Hanningfield ‘Uni-Mill’ cone mill is a high-performance machine for the sizing and deagglomeration of bulk materials in the pharmaceutical, food, chemical, cosmetic and associated industries.
Manufactured from stainless steel, the ‘Uni-Mill’ is hygienically constructed and boasts an ‘easy-clean’ design, allowing the system to be quickly stripped down for maintenance. Various special requirements such as ATEX, height adjustability, mobile frames etc. can all be accommodated.
The ‘Uni-Mill’ is designed and manufactured by Hanningfield in the United Kingdom
How Does it Work?
Material is fed into the cone mill via the in-feed chute, using hand-feed, gravity-feed or vacuum-feed. The material passes into the milling chamber, where the centrifugal force of the rotating impeller pushes material through the apertures of the screen (this process ensures that material will not pass through the screen until the particle is the desired size).
Once the material has passed through the screen, the finished product falls from the bottom of the mill to a receptacle beneath. Alternatively this can be integrated with various systems (such as vacuum transfer), such that milled product automatically passes to a downstream process.
‘Low Dust, Low Heat, Low Noise’ – Why is this important?
Low Dust: Minimal dust generation is important as excess powder escaping to the atmosphere can be harmful for operators and potentially hazardous to the operating environment. The ‘Uni-Mill’ cone mill produces comparatively little dust compared with many alternative milling processes. Moreover, the Uni-Mill can be integrated with various other pieces of equipment to create a totally-contained, dust-free milling process.
Low Heat: Ideally, a machine is used to process a material, not to change its core characteristics. The low heat generated by the Hanningfield ‘Uni-Mill’ means that the milled product is not altered by the temperature created during grinding. Moreover, many hygroscopic products do not fare well under high temperature conditions. By keeping the temperature optimised, the mill does not negatively affect the product.
Low Noise: Minimising noise is desirable to help comply with Health and Safety requirements for maintaining a safe working process environment.
What are the Typical Applications?
Typically cone mills are used for the size reduction and deagglomeration of powders, granules, tablets, foodstuffs etc across a wide variety of industries. A cone mill is generally used for reducing material to a particle size as low as 180µm (80 mesh).
Below are some common example applications:
Pharmaceutical: Milling powder, reclaiming tablets, sizing wet granulated particles before drying, sizing dry granulated particles before tabletting and more.
Food: Milling powder and spices etc., milling foodstuffs, deagglomerating dried fruits or other clumped material, reclaiming biscuits, reclaiming granola bars, reclaiming cereal and more.
Chemical: Milling powder, de-lumping raw material, wet granulation, reclaiming off-specification product.
Cosmetic: Milling powder, reclaiming off-specification product, de-lumping raw material.
Other: A cone mill can be used for size reduction of many different types of material, and for many different purposes. For more information and to discuss your specific requirements with our technical team, please contact us.
