Agglomeration is also commonly referred to as particle size enlargement. While powder agglomeration results in particles that look visibly different, chemically speaking, the solid particles are the same as before they were agglomerated. The only difference is that agglomerated particles are held together by binding mechanisms that leave voids between the particles. These voids add porosity to the product, making agglomerated materials more soluble and permeable than loose powders.
Depending on the material to be agglomerated, different powder agglomerating techniques and equipment can be used. Pelletizers, granulators, briquetters, and compactors are all examples of industrial agglomerating equipment for powders.
amixon® engineers a range of industrial mixing machines capable of agglomerating dispersive goods during the mixing process. Particularly suited for powder agglomeration is the RMG continuous granulator, a pin mixer model that operates at high rotational speeds to fling materials towards the walls of the horizontal mixing chamber, thereby creating a ring layer in which powdery particles aggregate into uniform granules.
There are three basic categories of industrial particle agglomeration techniques: pressure agglomeration, sintering, and tumble-growth agglomeration.
In pressure agglomeration, powders or other dry particles are mechanically compressed into the desired solid form. The applied force can vary in its intensity, from low-pressure extrusion to high-pressure rollers or punch compacting. Pressure agglomeration is typically a dry process requiring no moisture or binding agents. Some common household products that are manufactured via pressure agglomeration include charcoal briquettes and cat litter.
Sintering, also known as frittage, is a thermal agglomeration process during which the atoms within the materials diffuse and form bridges across distinct particles, joining them together. Sintering involves heating products without melting them, and as such is particularly well-suited for materials with very high melting points. For this reason, sintering is often used in powder metallurgy.
Tumble-growth agglomeration, also known as agitation agglomeration, is the most versatile method of agglomeration that is typically used in creating consumer products. This method uses a high-speed rolling action that causes powdery particles to come together as larger, denser particles.
As the rotary motion of the mixing chamber forces the powders to the edges, the particles move along the same path and gradually build up like a snowball rolling down a hill. Tumble-growth agglomeration is typically a wet process involving added moisture or binding agents.
Granulation, pelletizing, micro-pelletizing, and conditioning are all examples of common tumble-growth agglomeration techniques. Each process differs from the others in terms of the size, shape, distribution, and uniformity of the agglomerated particles produced. The RMG pin mixer from amixon®, for example, can be used as a wet granulator or pelletizer and customized to produce agglomerates with a wide range of diameters.

It was founded in 1880. The association develops technical guidelines and standards, particularly for pressure vessels. In addition it promotes science and engineering technology and offers professional training. In many areas the Association of German Engineers (VDI) has a similar function as ASME. ASME standards are used in many countries around the world. Knowledge and application of these standards is therefore also important for many companies based in Germany involved in exporting products and services.
The ATEX directive consists of two EU directives describing what equipment and work environment is allowed in an environment with an explosive atmosphere.

Procedure for automated cleaning of process engineering equipment. The definition and aims of CIP can be described as follows: Creating clean interior surfaces in production plants without significant modification of the fixtures required for production runs. Depending on the water pressure during cleaning a distinction is made between low-pressure cleaning (up to 10 bar) and high-pressure cleaning (25-65 bar).
Cleaned water is compressed to about 4,000 bar and directed onto the material to be cut by a sapphire nozzle. Sand can be optionally added to the water. The cutting jet acts as a thin diamond saw blade. CNC command data guide the cutting jet three-dimensionally over the workpiece.
The combination of the production of ideal mixed goods and the subsequent discharge of the mixed product maximizes the efficiency of the production process.
In many cases this results in undesirable agglomerates which have to be destroyed (deagglomerated) using shear dispersers or smizers (grinding-mixing). Examples of applications: For enhanced development of flavours, spices are separated, liquids distributed very finely, agglutinated materials are pulverised, lecithins are distributed in baking agents, and block grease and block lecithin are broken down.
Primary particles, which have a tendency towards agglomeration or aggregation in smaller grain sizes, can be de-agglomerated by rubbing and crushing. In practice, the deagglomeration takes place by shearing, impact loading and friction (cutting rotors, HighShearBlades, dissolver, milling machines).
amixon® guarantees technically ideal mixing quality, which cannot be improved in practice!
The EHEDG is devoted to the advancement of hygienic design and food engineering. EHEDG is a consortium of equipment manufacturers, food industries, research institutes and public health authorities, founded in 1989 with the aim to promote hygiene during the processing and packing of food products.

An emulsion is a more or less distributed mixture of the two liquids. A surfactant (= emulsifier) can be used to avoid subsequent phase separation. Emulsification can usually only be carried out under the influence of very high shear energies.
It was founded in 1927 and is based in Rockville (Maryland). It defines which raw materials may be used for gaskets, lubricating oils etc. in the production of food and drugs.

Compliance with the guidelines is intended to ensure long-term product quality and compliance with the requirements of the health authorities.
Distributive mixing means the distribution or adsorption of one component in/ beside another component.
Dispersive mixing is random and results from the flowing and swirling of the mix.

Ideally this qualification should be carried out by the equipment manufacturer, or the manufacturer should at least provide the associated documents.
The commonly used roughness parameter "Ra" is the arithmetic mean of the deviations from the centre line.
The downward movement of the goods takes place in the centre of the vessel. This type of rearrangement works quick, reliably and without any dead space at different filling levels. On demand choppers can enhance the liquid incorporation and homogeneity. The patented SinConvex® system enables particularly effective mixing and discharge. With SinConvex® mixing tools you achieve technically ideal mixing qualities that cannot be improved any further in practice – within minimum mixing times and
with maximum protection of the products. https://trademarks.justia.com/777/41/sinconvex-77741244.html
e.g. in the pharmaceutical industry, by definition the product-contacting surfaces of the equipment are cleaned without disassembly. Comparable with CIP – Cleaning in Place, although in addition superheated steam (via overpressure or carrier gases) or chemicals are used for sterilisation.
Such areas should be avoided in a mixer. The aim is to initiate total mixing across the whole volume with no dead space, in order to achieve an ideal mix of the whole mixer volume within a short time.
Using vacuum pumps, the pressure and humidity within the chamber are reduced. By lowering the atmospheric pressure within the chamber, the materials inside dry more quickly and at lower temperatures than in other types of industrial dryers. Because the temperatures are lower, vacuum drying is especially well-suited for drying heat-sensitive materials.
amixon® vacuum dryer models AMT and VMT dry their contents through contact with the indirectly heated walls. In this sense, vacuum drying is essentially contact drying in a vacuum.
Learn more about the vacuum drying process, its applications, and its advantages over other industrial drying techniques.
The system empties and dries itself completely and seals itself pressure-tight and vacuum-tight. It offers simple control, requires only one linear drive, takes up little in- stallation space and has a low weight. For the drying process large quantities of warm air can be put into the mixing chamber through the system. Installation positions: horizontal, vertical or inclined.
