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 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 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

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.

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 m³ 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.

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.

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.

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.

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.

Kaolin

 

Kaolin or kaolinite mineral is alumina silicate clay that was formed from the weathering of igneous rocks in moist and warm climate regions.

Kaolin is used in paper filler and coatings, in cosmetics, in ceramics as well as ceramic proppants, in addition to many filler or absorbent applications.

Pure kaolin is a relatively soft mineral, with a Mohs hardness of 2 – 2.5.  However, mined kaolinite may have a minor portion of abrasive impurities such as quartz / sand.  Upon heat treatment, kaolin will transform into various stages of hardness until it reaches a ceramic stage.

One of the standard methods of milling kaolin is with the Hosokawa Mikro ACM Air Classifying Mill.  The ACM has a rotating rotor disc with hammers which rotates with speeds up to 23,000 feet per minute.  The particle size is controlled by the internal air classifier, to provide sharp particle size distributions.  Various classifier designs are available, to produce from coarse (100 mesh) product down to a fineness of 400 mesh product or a D50 of less than 5 microns.  Abrasion Resistant options are available, including tungsten carbide tipping, Ni-Hard or Ceramic liners to assist with abrasive impurities and to assist with long life of mill components.  Warm air can also be used to dry the product while milling.

An alternate to the Hosokawa ACM for coarser grade Kaolin is the Hosokawa Mikro Pulverizer Hammer & Screen Mill.  The Mikro Pulverizer uses swing-hammers with interchangeable screen liners to produce a variety of products from 50 mesh to 150 mesh products.  The Mikro Pulverizer needs less air (less ancillary equipment) than the ACM and is a lower cost options for the coarser grind Kaolin products.

For ulta-fine (D50 < 5 microns) milling, the Hosokawa Alpine Super Orion Ball Mill  and Air Classifier are the best option.  These units come in a variety of sizes to meet your application needs.
