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.

The Mikro Pulverizer® consists of a high speed rotor assembly fitted with hammers. The grinding chamber is fitted with a cover containing a multiple deflector liner and a retaining screen at the point of mill discharge.
A screw mechanism is often used to introduce feed material into the grinding chamber. The grinding process is affected by three basic variables: the type of hammers, the rotor speed, and the size and shape of the screen opening.
There are two types of hammers: the “stirrup,” recommended where a fine particle size is desired; and the “bar,” which generates a coarser grind with a minimum of fines. Both types are tipped at the wearing edge with various abrasion resistant alloys. Rotor speed affects the fineness of the grind as follows: low speeds result in a coarse grind and high speeds produce a fine grind. Size and shape of the retaining screen openings also affect the product. In general, a finer screen opening will result in a finer grind. The retaining screen does not function as a sifting screen, except in coarse granulations.
Controlled Particle Size
Optimum particle size reduction can greatly affect chemical reaction speeds, solubility, weight, color, volume, appearance and strength of ground products. Mikro-Pulverizers® provide accuracy in particle size control because the grinding action is entirely mechanical. Once a mill is set to deliver a certain product, it will continue to produce exactly the same result without adjustment.
Grind, Blend and Disperse
Mikro Pulverizers® grind, blend and disperse in a single operation. Intensive action thoroughly mixes dissimilar ingredients into a finished product. Heat sensitive materials are handled by adjustment of mill speed, hammers, screen and discharge air relief, as well as with pneumatic conveying. Conditioned air may be bled into a grinding chamber, or the feed may be pre-conditioned or chilled. The Mikro Pulverizers® comes in many model sizes from small pilot scale to massive production models.

With Alpine High Pressure Roller Mill products are produced with a precipitous granule distribution. The high pressure roller crusher is also called roller crusher or roller press.
The significant difference of high pressure roller grinding compared with compaction is that the press forces between the rollers are lower because no new adhesive forces need to be created.
The mill feed is transported to the most narrow gap by the counter rotating rollers through friction effects. Both rollers are pressed against each other using hydraulics. This milling force is transferred to the mill feed. Through selective contact of the individual granules are created at extremely high inner tensions which lead to fractures.
The use of the optimal milling force leads to compact mills with extremely low energy requirements. Because only the outer particles of the material bed have contact with the surface of the rollers, milling that is almost contamination-free is possible.
High Pressure Roller Mills are used in the cases of medium-fine crushing of hard materials such as ceramics, minerals from 5 up to 9 on the Moh's hardness scale, metals and metal alloys. High Pressure Roller Mills are used in continuous operation or in a closed circuit with screening machines or classifiers.

Shurfeed™ cutting chamber design allows material to
fall directly in front of the rotating knives and to be pulled quickly
through the cutting action for fast, complete granulation without piece
bounce and flyback. Three steep angle rotor knives and two bed knives
mounted in Double Angle Cut™ configurations reduce energy consumption, noise, heat and fines, while increasing throughput.
Shurfeed® cutting chamber design allows material to fall directly in
front of rotating knives to be pulled quickly through the cutting
action for fast, complete granulation without piece bounce and
flyback. Only Polymer Systems gives a clear, unobstructed feed opening
equal to rotor diameter for maximum performance through every inch of
the cutting circle. This unique design maximizes granulator capacity,
eliminates bottlenecks at the entrance to the cutting chamber and
dramatically increases effective screen area for fast throughput. Ask
for a comparison!

Mikro ACM® Air Classifying Mills were invented by HMPS in the late 1960’s and are one of the most versatile types of size reduction equipment available in the market. These units while being capable of producing fine, medium and coarse grinds for a wide variety of materials for Food, Pharmaceutical, Chemical and Mineral industries, require very little maintenance over their life span. The basic design of these mills is the impact size reduction that is coupled with an internal dynamic classifier which controls the outlet (product) particle size via recirculating the coarse particles back into the grinding zone.
There are seven main factors which determine particle size distribution for the Mikro ACM® Air Classifying Mill. When varied, the rotor type and speed combined with the liner and hammer count affects the production of fines. The separator type and speed affects the top size of the product. And lastly, the airflow governs the throughput as well as top size and fines generation. With the endless available options a machine can be configured to process just about any material that is below MOH’s hardness of 5.

The Mikro Atomizer® Air Classifying Mill uses air flow to convey materials to the grinding zone. Size reduction occurs when hammers fitted to the rotor impact particles at 4,000 to 8,000 RPMs. A deflective liner returns oversized particles to the hammer impact zone for further reduction. The ground materials are then conveyed to the classifier wheels which are mounted to the grinding rotor. Larger particles are rejected for regrinding as the desired particles are air conveyed by internal fan blades and exit the mill for collection.

[post_content] => Prior to the development of the Mikro LGM
® Long Gap Mill, materials had to be dried and de-agglomerated in two separate operations. For example, a rotary drum dryer was used to dry materials that had been wet milled. A separate grinding/de-agglomeration process followed the drying operation. The Mikro LGM® Long Gap Mill is Hosokawa's solution for streamlining these two operations into one continuous process. This type of dryer is commonly referred to as a "gap" type mill. It is called a "long" gap mill because of the long annular gap path the process material takes from the inlet to the discharge. By combining several operations such as flash drying, de-agglomeration and surface coating into one operation, a Mikro LGM® Long Gap Mill eliminates the need for multiple material handling systems which subsequently increases process efficiencies. The dried powders often do not require any further size reduction. Both slurries and wet cake can be handled.
The Mikro LGM® Long Gap Mill modular design expands its range of applications beyond drying and deagglomeration. For dry grinding, modular options include: direct and independent drive classifiers; pre-grind rotor stage; an integrated jet mill and variable stage rotor design. The smaller size Mikro LGM® Long Gap Mills are engineered with a split body housing for easy maintenance and cleaning. The LGM processes high moisture materials in wet cake form as well as dry solid feed stocks up to one inch. Finished product particle sizes of D97 < 10 microns can be achieved.
The Mikro LGM® Long Gap Mill has demonstrated superior performance over all other mechanical mills in reducing grit from pre-sized and agglomerated powders. Typical results are less than 1 part per million (ppm) residue on a 44 micron sieve starting from a feed stock with a residue of 120 ppm.
This performance is achieved with a powerful grinding mechanism coupled with a precision internal air classifier. The air classifier is designed for a theoretical cut point of 2-5 microns, depending on the particle density. Rejected particles are forced away from the classifier wheel and redirected outside of the mill back to the material inlet using a patented re-circulation system.

As requirements in the pharmaceutical industry continue to ask for tighter particle distributions, additional steps such as on-line classification may be required. The Mikro® Acucut Air Classifier utilizes dual stage operating controls to ensure sharp cuts and narrow band particle size distributions typically below the 10 micron range. This permits control of maximum and minimum particle size diameters with unparalleled accuracy. With precise control of the air flow and rotor speeds this unit will produce the same sharp cuts each time, every time. The high energy dispersion also ensures that the maximum percentage of fines is reclaimed. Easily operated, cleaned and maintained, the Mikro® Acucut Air Classifierr keeps downtime to a minimum.
Options are available for effective control of product contamination, protection against corrosion, handling abrasive materials and classifying adhesive powders. The Mikro® Acucut Air Classifier is ideal for chromatography materials, alumina, silica, toner and metal powders. Extremely high dispersive energy applied to the process material ensures unparalleled yields even with sticky and difficult to disperse products.
The Mikro® Acucut Air Classifier is a forced vortex unit designed to disperse, then classify fine particles into coarse and fine fractions. High energy dispersing air enters the rotor radially around the entire outer edge. Feed material enters this dispersion air zone through an inlet in the rotor ring. Particles are acted upon by centrifugal and drag forces. Air carries the dispersed fines inward to the central fractions outlet, coarse move outward to the rotor periphery. Cut points are adjusted by airflow, rotor speed or both.

The wet material is fed through customized feeding systems into the grinding and drying section of the dryer's main body. The grinding rotor disperses the wet material into very fine particles and the fine particles are fluidized in the grinding chamber by temperature-controlled, hot gas coming in from the air heater.
The hot air (or inert gas) can be heated up to 650 °C and as the wet product is dispersed, it is reduced in size in the bottom section of the dryer. The system is kept under a negative pressure by the exhaust fan and the surface area of the product is increased enormously so that water (or other solvents) is evaporated instantaneously.
The dry and fine particles are conveyed with the gas stream to the top section of the dryer where a separator classifies the particles by size. Then the particles pass the classifier at the set cut point and are conveyed with the exhaust air to a powder air separating system like the cyclone, cyclone filter or cyclone scrubbers.
The Micron Dryer flash dryer retains a fluidized bed of product in the drying chamber to ensure a low level of adhesion of wet material on the inside wall of the drying chamber. Moreover, process parameters like classifier speed and outlet temperature can be adapted to control moisture content and particle size of the end product.
- Ultra fine regular end product - Due to its specially designed dispersion rotor, our flash dryers are able to produce ultra-fine powders in one step from suspensions, slurries, pastes and dough, filter cakes or wet powders.
- High evaporation capacity - Due to the combination of high ?T with a good dispersion of the wet product in the air, our flash dryers can evaporate large quantities of liquids.
- Compact design - Compared to other direct drying technologies, the flash dryer requires up to 50% less space.
- Multi-purpose - Filter cake or slurry, in the same machine. Therefore with the Drymeister-H unlimited mechanical dewatering is possible previous to the final drying stage.
- Easy access - Either for cleaning, inspection or maintenance inside the dryer, our flash dryers offers the best accessibility from the market, regardless which size.
- Various systems available - Open, closed- and recycle system concepts.
