[post_content] => The Alpine UPZ Ultraplex Fine Impact Mill are truly flexible. Designed with ultimate versatility in mind, this one unit can accomplish a multitude of size reduction tasks. A wide variety of grinding inserts are available through the entire line of mills. The mill is also offered with a counter-rotating (Contraplex) set of pins for added shear for difficult to mill products. The pharmaceutical version of this work horse has been designed specifically for cGMP compliance from the ground up. Size reduction of soft to medium soft material can be accomplished at rates from 3 to 700 Kg/hr depending on feed material and final size requirements.
Alpine UPZ Ultraplex Fine Impact Mill can also be integrated into Stott Isolators. This arrangement provides a completely integrated system capable of containment levels as low as 1 micro-gram/cubic meter.
Operation of the mill is simple. Material is introduced to the mill via feed device such as a rotary air lock or volumetric/gravimetric feeder through the mill's inlet. The inlet directs the material to the grinding chambers center. The grinding toll rotates at high speed, creating centrifugal force that will accelerate the pharma-powder outwards. The particles outward flow hurls them at high speed against the pins or other grinding media where the impact will cause the particles to fracture.

[post_content] =>
The grinding air is injected tangentially via Laval nozzles in the nozzle ring into the machine. This causes a spiral jet of air to form in the grinding zone, from which the mill derives its name. A high pressure forms in the mill as a result of the spiral flow of air that can rise to 1 bar overpressure in operation without product. The integrated injector is charged with compressed air which ensures that the product is conveyed into the machine against the overpressure present in the machine. This, however, is associated with a considerable compressed air consumption, which can be as much as 30% of the total grinding air requirement.
The feed product circulates close to the nozzle ring and is thus intercepted repeatedly by the air jets exiting the nozzles. Comminution is the result of inter-particle collision caused by the particles flowing at different speeds in the nozzle jet. Comminuted material is conveyed along with the air to the discharge, the spiral flow subjects the particles to a classification: only fine particles are discharged, coarse particles remain in the mill.
Alpine® AS Spiral Jet Mills are characterized by a special geometry of the mill housing in the area of the discharge, which contributes towards a finer classification effect and a sharp top cut.
The product also has an effect on the air flow within the machine: the more product there is in the machine, the more the spiral flow is braked and the lower is the centrifugal force and the coarser the end product. The relationship of the product to the classifying air flow rate is therefore the most significant parameter for setting the fineness of the spiral jet mill. In principle, different nozzle angles can also be used to achieve the required fineness values, whereby the complete nozzle ring must be exchanged in this case.

Benefits
- Continuous drying, milling and classifying in a single compact system
- Safe drying of temperature-sensitive products — even at elevated temperatures
- Produces ultra-fine, uniform powders in just seconds
- Handles moist solids with up to 80% moisture content — including slurries, pastes, doughs, filter cakes and wet powders
- High evaporation capacity and fast thermal transfer
- 30–40% lower energy consumption per kg of evaporated water compared to conventional drying technologies
- Small footprint and excellent accessibility for inspection and cleaning
Rotor Types
Hosokawa Flash Dryers are available with a choice of three rotor types, selected according to product characteristics and specific process goals. Each rotor offers distinct advantages to suit a wide range of applications:
- DMR Rotor
A high-speed multi-blade rotor designed for strong dispersion, generating a powerful air vortex with tip speeds of up to 110 m/s. Ideal for maximum dispersing performance.
- MDH Rotor
A horizontally driven rotor with swinging hammers for intensive grinding. Recommended for processing slurries and pastes requiring strong milling.
- MDV Rotor
A vertically driven grinding rotor that gently disperses wet agglomerates and solids. Suited for mild dispersion and grinding of heat-sensitive products.
