Mini Cyclomix

Perfect for laboratory-scale use, the standalone Mini Cyclomix is based on the technology and processing principles of the full size Cyclomix range. Ideal for accurately blending DPI formulations for the highly regulated pharmaceuticals industry, the comparatively diminutive Mini Cyclomix features exchangeable processing bowls (100mls, 1 litre and 2 litres) and offers reproducible processing results, accurate temperature control (using a heating/cooling jacket), single layer coating of materials, rounding off and densification of particles, as well as high-quality homogenous and lump-free mixtures.

As with the standard version, most of the energy used to facilitate the processing is generated by the configuration and close positioning of the internal paddles in relation to the conical vessel wall, the high-speed rotation of the paddles and the addition of a high-quality blade, making it a very efficient high-shear blender. Full discharge is achieved by our unique, centrally located, ISEM ball segment valve.

For the handling of hazardous or potent materials, off-line filling and discharge can be achieved by the integration of a Hosokawa Micron Ltd containment isolator. Sterile/aseptic and CIP/SIP designs are also available.

We would be delighted to advise and support your projects that may require reproduceable process up-scaling from the Mini Cyclomix to a production-scale Cyclomix.

*Mini Cyclomix – 100ml, 1 litre and 2 litre exchangeable bowls

The highly regarded Hosokawa Micron Cyclomix offers high-speed, intensive batch processing of challenging cohesive powders and heat-sensitive materials with a low melting point, and can effortlessly mix powders with liquids, mix wet powders together and mix and disperse pastes and slurries. Additional processing capabilities include coating, spherization, particle design, heating and cooling materials, vacuum drying and de-agglomeration.

The Cyclomix’s versatility is underpinned by its uniquely engineered, patented processing technology, including a conical-shaped mixing vessel, featuring specially designed and configured paddles, an impact blade and a domed cover for highly efficient homogenisation of materials in the quickest time possible.

Product enters the widest part of the domed mixing cone from the top and drops downwards to the narrowest part of the cone. The Cyclomix’s cantilevered central rotor is driven from the top and operates a series of paddles that are specially positioned inside the cone, close to the vessel wall, to create an upward and downward flow in sequence.

The uppermost paddle is the largest and has a tip speed of up to 30 metres per second. This paddle configuration allows for optimal acceleration of the processing material, which centrifugal forces move upward and outwards against the interior of the vessel wall in a spiral movement. As the rotor is driven from the top, no seals or bearings come into direct contact with the product zone.

Strong frictional forces are generated by the paddles, assisted by the increasing rotor diameter as the cone widens. When the material reaches the top of the Cyclomix’s mixing vessel, it enters the vessel’s domed area, which deaccelerates the material and drops it downwards towards the centre of the cone, where a rotating blade, positioned just below the domed area, provides additional impact and shear forces, dispersing and agglomerating the cohesive powder (and any other material) as it falls and continues to circulate and quickly blend.

The combination of the Cyclomix’s unique engineering, the processes of accelerating and deaccelerating the material while it moves up and down in the cone, the shearing forces created by the paddles and the particles themselves and the very efficient blade ensure super-quick, high-impact mixing, resulting in perfectly homogenised, high-quality end products.

An optional heating/cooling jacket is available for intensive thermal mixing, with temperature-controlled heat transfer between the jacket and product, enabling accurate and effective heating and cooling of products including melt binders and wet agglomerates.

Discharge of the blended product is effortless, impressively thorough and quick, thanks to the centrally located outlet and our unique ISEM ball segment valve, positioned at the narrowest point of the conical vessel’s cone, which also ensures a maximum yield can be consistently achieved.

Hosokawa Micron’s Cyclomix high impact batch mixer can be supplied as an individual piece of equipment but can also be supplied as part of a larger, Hosokawa Micron-designed, process system, combining multiple ancillary equipment.

Depending on the application and requirements of the material, ancillary components for a process system might include a pump, flow sensor, dosing pump, retractable cleaning nozzle, charging hopper, contained filling drum, split valve, end product drum filling, mixer lift, HEPA filter, electric air heater, pressure sensor, powder and liquid dosing, sampler and a control system with cabinet, all of which Hosokawa Micron can supply and fit.

Conveniently, the Cyclomix is available in a comprehensive range of sizes and bespoke designs to address the requirements and concerns of highly regulated sectors, such as the food, chemical and pharmaceutical industries. As such, we can offer hygienic, vacuum/pressure, sterile/aseptic and wear/corrosion options, along with high-performance containment equipment, such as a tailor-made isolator, which can be designed, engineered and built in-house by Hosokawa Micron Ltd.

The Cyclomix is the high-impact batch mixer of choice for high-profile cosmetics companies the world over. Perfect for efficiently manufacturing premium-quality face powders with complex formulations that meet the demands of the industry and the end user, the Cyclomix produces perfectly blended, lump-free batches of consistently coloured and textured fine powder by continuously spraying liquid from its central spray nozzle into the conical mixing vessel. The colour pigments are thoroughly dispersed in the vessel without over-wetted the powder mixture, which overcomes any need for further milling of the powdered material.

Pressed metal powders are used extensively for products such as automotive gear wheels, power tools, small domestic appliances, locks and pumps. The Cyclomix is the ideal solution for introducing a binder to a metal powder mixture prior to pressing or sintering. The batch mixer also excels when creating uniform coatings on metal powder particles, including coatings of oil for preventing oxidisation and coatings of wax to ease the release of metal ingredients from moulds.

Dry powder inhalers (DPIs) containing very fine active pharmaceutical ingredient powders are increasingly popular for delivering respiratory drugs to help treat illnesses such as asthma and even diabetes. Fast absorption of the medicine can be critical, particularly in the case of asthma, so formulation quality is key.

Active ingredients are mixed with an excipient, such as lactose, which provides cohesion in the inhaler and separation of the API and excipient when it reaches and is absorbed by the lungs. These exact characteristics require highly specialist processing for the inhaler to perform to optimal levels.

This is where the Cyclomix is a particularly useful solution, as it can exactly blend the small amounts of APIs and large amounts of excipients so that the active ingredients in the dry powder mixture are successfully and fully released when inhaled. Low mixing energy is required for this purpose, which the Cyclomix can achieve, eliminating the risk of particle erosion and a poor-quality product. The Cyclomix can also densify APIs prior to them being made into pills.

When making high-quality printer toner, the Cyclomix blends dried cohesive toner powder with flow-adding and charge-controlling agents, using high-shear forces to coat the toner particles with the additives and provide powder with excellent flow properties and optimal conductivity behaviour for the printer. A cooling jacket prevents the mixture from heating up as it is blended. Similarly, the Cyclomix is often chosen to coat various chemicals used in fire extinguisher powder.
