            [post_content] => 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.

 	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.

            [post_content] => 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.

            [post_content] => The Flexomix agglomeration system is a powerful combination of a number of functions:

 	Powder handling system
 	Powder dosing system
 	Binder dosing system(s): water, steam, and other liquids
 	Flexomix mixer and agglomerator (FX),
 	Fluid Bed Dryer and Cooler (FBD)
 	Air system including blower and heating/cooling equipment
 	Air exhaust system including cyclone and filter
 	Product classification and size crusher (if necessary)
 	State-of-the-art integrated control system

This combination means that base powders can be fed as a mixture or as multiple powders in parallel. An accurate, gravity fed system ensures a constant powder/liquid ratio and a liquid dosing skid ensures accurate flow control and a constant powder/liquid ratio in the agglomerator. This liquid skid can be equipped with a stirrer or a heated tank for example, or in the case of solution binders, a preparation tank.

Powders and liquids can be fed into the unit through top inlet(s) using air atomizers which combine with turbulent air flow inside the mixer’s vertical chamber, mixes powdery and liquid particles intensively and instantaneously.

The Flexomix has been designed to be compact whilst allowing for homogeneous mixing of powders and liquids at capacities of up to 40 000 kg/h. To achieve this, the Flexomix has a flexible mixing chamber and a shaft with pitch-adjustable mixing blades that rotate at high speed. The resulting granulates have a porous, raspberry like structure in particle sizes of 0.1 to 1.2 mm and with a D50 between 300 and 700 micron at low to medium density.

The wet granulates from the Flexomix are then processed in the Fluid Bed Dryer which is divided into several compartments. The front end compartments are used for drying; the rear for cooling. Product height in the bed can be altered from between 100 and about 500 mm (average 300 mm), and depending on the application, variable residence times can be achieved by adjusting the bi height.

The Flexomix agglomeration system has an air system and air exhaust system including cyclone and filter, as well as a one or two-deck sieve and an oversize crusher for product classification.

In the food industry, Corn Starch is used either as a food product itself or as an additive for thickening, preservation and quality enhancer in baked foods, confectioneries, pastas, soups and sauces, and mayonnaises. Starch is a polysaccharide of glucose made of two types of α-d-glucan chains, amylose, and amylopectin.

The making of corn starch is comprised of the steeping of ground corn in a mixture of ammonium hydroxide and water. After a set period of time, the material will be at the required pH level and the material will be dewatered and dried. This dried material will be milled to various end particle sizes dependent upon specific use/application.

Hosokawa’s technology and roll is in the size reduction of the dried material. The desired end sizes range from coarse grinds of less than 80 mesh to finer grinds of top sizes below 200 mesh. There are even requested end particle sizes of less than 35 µm.

To achieve the above-mentioned particle sizes, Hosokawa equipment would include the Mikro-Pulverizer^® Hammer and Screen Mill and the Mikro-ACM^® Air Classifying Mill.

An additional application is the Modification of Starch to achieve a homogeneous product with exactly the specified moisture content. In addition, another end result is to produce an agglomerate with optimal flow properties, minimal dust, and optimal dispersion characteristics.

To achieve this modification, the equipment would include the Hosokawa continuous agglomeration system, comprising a Flexomix mixer/agglomerator and a fluid bed dryer/cooler.

Corn Starch is an organic material, and therefore has a potential for explosion. As with all organic materials, the system must be designed to safely handle the potential for a dust explosion. System protection can be obtained by incorporating any of the following basic design possibilities:

Designing the entire system for over-pressure and containment of the explosion as shown in this picture
Venting of the system to safely relieve the over-pressure
Operation under an inert atmosphere to remove the explosion potential
Utilizing a suppression system to quench the explosion before it propagates
