[post_content] => The Vitomix is equipped with two symmetrical ribbon screws mounted on an orbital arm that transports the product from the bottom of the vessel to the surface. The material flows downwards through the center of the vessel by gravity whilst the high rotational speed of the agitator ensures mid-shear mixing in very short batch times.
A distinctive factor about the Vitomix is the double ribbon screw which enables a transport capacity of up to eight times that of standard conical screw mixers. The result is a substantial improvement in mixing efficiency and a much more efficient and faster mixing process even at lower speeds.
The design of the two conical screws creates a fluidized bed in the upper part of the mixer cone that is perfect for adding liquids. A liquid spraying system can be fitted through the hollow axle, providing flexibility in the location and the number of nozzles and lances you choose; without influencing mixing properties or spraying on metal parts.
The Hosokawa Vitomix can be tailored for use in a wide variety of applications, these include:
- Fast mixing of powders, pastes and slurries
- Addition of liquids and fats without the use of lumpbreakers
- Gentle mixing combined with mid shear mixing in one machine
- Coating powders with powders
- Granulating
- Flavoring
- Coloring
- Heating / cooling

The Alpine AFG Fluidized Bed Jet Mill is suitable for fine and ultrafine size reduction of any material up to a Moh's hardness of 10 that can be fluidized by the expanded compressed gas in the grinding chamber. The addition of an internal forced vortex classifier is capable of controlling particle top sizes (D97) as low as 3 microns.
The key to maintaining a consistent particle size distribution is the integral air classifier. Air classification is defined as the separation of bulk material according to the settling velocity in a gas. In this type of jet mill two opposing forces act on the particle, the mass force and the drag force. The particle size at which the mass force and the drag force act equally on the particle is defined as the cut point. If the mass force (or weight of the particle) exerts a greater influence on the particles coarser than the cut point, they are returned to the grinding zone of the jet mill and reduced further. If the drag force (or airflow through the classifier) acts upon particles finer than the cut size, they are carried through the classifier wheel and recovered as product.
By changing the parameter of classifier wheel speed, airflow, and grind pressure, a wide variety of particle size cut points can be achieved. Achievable particle size ranges include D97 as low as 3 microns to as high as 60 microns.

The
Model E is unique in that it has an external coarse recycle system which
extracts oversize material and returns it to the grinding chamber for
additional processing. The feed design of the Model E introduces product from
under the main rotor; ensuring that 100% of the feed material comes in contact
with the impact rotor for optimal grinding efficiency.
The
Model E can also be used for grit reduction applications when tight particle
top size control is required, such as in the case of Carbon Black, Iron Oxides,
and Clays.
The
processing of light density materials may become problematic as the lighter
material will float in the classifier zone and will not easily be recycled to
the impact zone of the mill. The external recirculation system of the Model E
and the bottom feed ensure that all the product is returned to the grinding
chamber for more efficient size reduction.
Cohesive
materials can in some instances stick and build up in the standard Mikro ACM®
- Air Classifying Mill, due to the expanded surface area of shroud
and baffle assembly and the reduced tangential air velocity. The Model E has no
internal shroud and baffle and therefore no internal components to assist in
accumulation of product. Also the internal airflow is allowed to develop
maximum velocity thereby keeping the mill chamber walls free from accumulation.

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.

The Alpine CW Contraplex Wide Chamber Impact Milis a fine impact mill with two driven pin discs. In counter-rotating mode, much higher relative speeds are possible than with the UPZ fine impact mill with only one driven pin disc. The highest relative speed develops at the outermost pin rows and can be up to 250 m/s. The feed material should be brittle with a maximum Mohs hardness of 3.
The fineness can be adjusted by altering the pin disc speeds. The centrifugal forces acting on both discs ensure that even moist, greasy and sticky products can be processed. The design with the wide-chamber housing is ideal for processing these kinds of products. The feed material is often embrittled by intensive mixing with liquid nitrogen.
The mill door can be hinged opened wide to permit easy cleaning. Dependent on the machine size, product feed is either from the front via the machine door or from the rear of the mill housing.

In the case of jet milling, one takes advantage of the fact that as compressed gas exits a nozzle, it is accelerated to extremely high speeds. In expanding, the energy contained in the compressed gas in the form of heat is converted to kinetic energy. The speed of sound is initially a natural limit for the exit velocity.
But by using Laval nozzles, the exit velocity can be increased to above the speed of sound. Laval nozzles are characterized by their hourglass shape, which widens downstream of the narrowest cross-sectional point, the nozzle throat. The length of the divergent part of the nozzle is adapted to suit the operating pressure. Compressed air of 20°C and 6 bar overpressure is frequently used as the grinding gas, and delivers nozzle exit speeds of around 500 m/s.
As a result of drawing in gas and product from the fluidized bed, the speed of the gas jets sinks extremely rapidly after exiting the nozzles. Comminution is a result of inter-particle collision in the jets of air and also in the core area, i.e. the point where the opposing jets intersect. Jet mills are impact mills which are used to achieve maximum fineness values. Such particle sizes can only be obtained in connection with an air classifying step. Spiral jet mills have a static air classifier integrated into the mill housing, whereas fluidized bed opposed jet mills are equipped with a dynamic deflector-wheel classifier.
The fineness is set as a function of the classifying wheel speed. All-important is a high product loading of the nozzle jets in order to achieve a high concentration of particles and thus high impact probabilities. The patented Megajet nozzles were developed with this in mind. They consist of four small nozzles which as a result of their close proximity generate an under-pressure at their common center, and thus draw particles from the fluidized bed direct into the center of the nozzle jet. The product level in the machine is controlled by means of load cells or by monitoring the current loading of the classifier drive.

Ball mills are giant drums that are filled to between 30 and 40% of their volume with freely moving grinding media - in this case balls. The diameter of the balls is between one and several centimetres to suit the application - smaller balls for fine milling results and larger ones for coarser milling tasks.
The drive sets the milling drum into slow rotation and the bed of milling media is thus activated, i.e. the balls are lifted and then impact back against the bed. Ball mills are usually operated at 75% of the critical speed. The critical speed is the speed where, mathematically calculated, the grinding media would centrifuge out. Mills of 2 m in diameter therefore rotate in operation at about 23 revolutions per minute, which corresponds to a peripheral speed of 2.4 m/s.
A mill of this size equipped with steel grinding media converts approx. 50 kW per mÂł of feedstock. The feed product is fed continuously through the trunnion and is discharged through slots on the opposite side. The discharge rate can be adjusted as a function of the number of open slots. The ground product is transported - often pneumatically - and is charged to a downstream classifier. The coarse material is returned to the mill together with the feed product.

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.

[post_content] => The Mikro® Classifier is characterized by its optimized cyclone-classifier principle. Because of the optimized flow pattern and the use of a high-efficiency classifying wheel, the Mikro® Classifier is especially suitable for ultrafine classifying operations in in-line mode.
The feed product is fed tangentially to the top of the classifier. The classifying wheel separates the feed product into a coarse fraction and a fines fraction. The classifying air and the fines pass through the
classifier wheel, whereas the coarse material settles on the housing wall. A flow of secondary air introduced tangentially above the product discharge recirculates any unclassified material to the classifying wheel for renewed classification, whereby agglomerates are dispersed and the material is then distributed uniformly in the classifying zone. The optimized classifying wheel geometry results in a high product yield at an extremely high precision of cut. In addition, the low pressure drops result in low energy consumption and correspondingly lower operating costs.
The Mikro® Classifier was designed for all types of fine to medium-fine products. It is especially suitable for powder coating classification aimed at reducing the ultrafine portion under 5 – 10 µm.

[post_content] =>
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.
