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

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 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.

Talc Compaction

Compaction of Talc:

Talc is used in diverse sectors. Among those diverse sectors, the plastics industry plays a major roll with using talc as an additive for polypropylene. Those polypropylenes are applied in the automotive industry for improving the mechanical properties of bumpers, for improving the shape accuracy of the interior and for extending the temperature range in the technical area.

High bulk weight combined with good dispersibility are the most important characteristics for the implementation of talc in the plastics industry. Furthermore, the granulating procedure should possibly work without water because otherwise the material would have to be degassed in a complex way for further processing it in extruders.

The compaction of talc on roller presses meets those demands. Due to the relative low bulk weight of fine talc, the roller presses must be equipped with a vacuum de-aeration for this purpose. Depending on the feeding material and its grain size, different throughput capacities can be achieved with a roll press of the ARC MS series.

Process:

The KOMPAKTOR  is designed for the de-aeration of talc (densification). A high bulk density without creation of hard spots will be achieved during the densification process.

The powder will be fed into a large silo above a horizontal screw. An agitator or vibration nozzles above the screw prevent any bridging of the light talc powder. The horizontal screw has a vacuum de aeration system for increasing the efficiency of the screw and increasing the throughput of the Compactor.

The material will be fed with multiple screws into the gap of the compaction rolls. In the conical hopper of the multiple screw feeding unit there will be also a vacuum de-aeration system.

The talc will be compacted to soft flakes in the roller gap of the Compactor ARC MS series.  After compaction the material is normally packed into super sacks or normal bags.


During the compaction/granulation process this fine dust will be granulated to dust free granules with a bulk density of more than 500 g/l.

Example for ARC-MS 60

– Feeding bulk weight:  g/l = 12.5 lb/ftÂł

– Final bulk weight:  min. 600 g/l = 37.5 lb/ftÂł

– Throughput:  approx. 4 Mtons/h

– Feeding bulk weight:  280 g/l = 17.5 lb/ftÂł

– Final bulk weight:  min. 600 g/l = 37.5 lb/ftÂł

– Throughput:  approx. 6 Mtons/h

With this process, bulk weights up to 800 g/l = 50 lb/ftÂł can be obtained, irrespective of the feeding material. However, this results in a reduced throughput capacity.

With talc qualities as being used in the paper industry (feeding bulk weight approx. 300 g/l = 20 lb/ftÂł), bulk weights of approx. 1.000 g/l (= 62 lb/ftÂł) can be gained. The throughput of an ARC MS 75 machine ranges in this case between approx. 5 – 6 Mtons/h.
