Classifying technologies 

Agitated media mills stir the grinding media to break down the target material into ultra-fine particles. The grinding media generally consists of spherical metallic or ceramic beads that are stirred into action by the agitator. Agitated media mills are designed in both vertical and horizontal configurations. The choice of a suitable mill depends on the properties of the material to be processed, the particle size required, the production volume, and the desired grinding time.

Agitated media mills

Classifier mills combine a grinding/milling system with a particle size classifier which continuously recirculates over-sized particles back into the grinding zone. The classifying action ensures a uniform final product with a narrow particle size distribution. Important considerations for choosing a classifier mill include the desired particle size, the maximum particle size variance allowed, and the physical properties of the material.

Tumbler sieve for classifying and dedusting granular materials

Dedusting is the process of removing dust particles and other undesirable particles from products. Certain products, especially those in the food and pharma industry need to meet strict quality standards. And therefore, fine dust needs to be effectively removed to meet those standards. In order to get started, you will need specific dedusting systems. You can almost think of dedusting as a sort of vacuum cleaning process. Dedusting equipment generally uses compressed air to create a suction that is able to separate the dust from the product. For example, pharmaceutical tablets needs to be dedusted in order for the product to be safe for consumption. Pellets are another common product that require dedusting.

Dedusting

Industrial filtration equipment separates solid matter from liquid by using a filter medium. The filter allows only the fluid to pass through but retains the solid matter. The choice of filtration equipment depends on the particle size, the consistency of the mixture, and the nature of your product.

Filtration

Industrial separation equipment encapsulates the separation process which is to separate components of a liquid mixture, for recovering dissolved solids from liquids. The choice of a suitable technology depends on the identification of the key physical or chemical property, such as size, mass, density, or boiling point, which sets the product of interest apart from the rest of the components. Separation technology is widely used in the pharmaceutical and chemical industries for the isolation of active ingredients and high-purity chemicals. As well as in waste management and recycling industries.

Separation

Sieving machines are available in various designs such as linear sieves, tumbler sieves, and vibrating sieves each employing a different sieving action. The choice of a suitable sieving machine depends on the desired particle size distribution, required amplitude and frequency of vibrations, and the physical state of the mixture. Sieving machines are used for removing dust from granular products and for grading grains. They are also used for the classification of granular material and the separation of solids from a slurry mix in the food processing industries.

As the particles get smaller, they move to the center of the chamber and pass through a classifier going to the cyclone where a filter separates the gas stream and micronized powder.  The unit is easy to clean and assemble and it is constructed of high-grade materials such as AISI 316L stainless steel or Hastelloy.

Laboratory jet mill

Seeds coming from the same plant might have different sizes and shapes. The germination percentage of small seeds is lower than large(r) seeds. Larger seeds often have a higher germination speed than small seeds. For this reason, seeds have to be sorted according to their diameter before processing. For this, a seed sizing machine is needed

<h2>Accurately classifying seeds by diameter using an unbalanced calibration machine</h2>
The CCM-4900 Seed Calibration Machine sorts fine seeds according to their diameter size. The technology is designed by Seed Processing Holland and reaches a size accuracy degree of up to &lt; 3%, making it especially suited for breeding and seed foundation stations. The system separates all kinds of seeds uniformly into anti-static bins and calibrated seeds are separated into four fractions: three lower sizes and one upper size. This machine is slightly different to a gravity separator because it focuses on size/shape instead of weight.

The screen boat of the CCM-4900 holds two screens using a pneumatic clamping system with screen, while its unbalanced motors ensure silent operation throughout. The adjustable vibration function can operate at different time intervals. Meanwhile, integrated dampers prevent the transmission of vibrations to the frame. It is recommended to utilise this piece of equipment on a smooth and flat surface to further reduce any vibrations. Having said that, the dampeners do a great job at absorbing unwanted loud noises.

If you're running a processing plant and looking to maximise the output of any crop you might be growing then this will most help you achieve that. Furthermore, that applies to all crops that are grown from seeds including various types of vegetables, crops and hemp.

If you're growing crops in rows, then using the CCM-4900 will drastically improve the sorting process and allow you to use only the best seeds to ensure a successful harvest.

Machine For Sizing Seeds

Industrial measurement equipment is used as a crucial step before products leave the production line. These measuring instruments check for correct dosage and standards. Equipment for measurement and control employs a wide range of technologies to detect inconsistencies in volumes, sizes, weights, and fill levels as well as to inspect goods for quality against a set of criteria. Specialized measuring tools allow you to minimize the probability for error to its lowest possible, ensuring that both products and packaging meet your benchmarks.

Measurement &amp; Control

Widely used in the construction industry as filling materials, calcium carbonate is usually made from pulverized limestones.

<h2>Mill for fine grinding and drying of soft to medium-hard minerals</h2>
The Pendulum Mill PM by NEUMAN &amp; ESSER is a roller mill used for fine grinding and drying soft to medium-hard materials such as clay, bentonite, limestone, and many other minerals. It is a robust and durable design of combined grinding, de-agglomeration, drying, and classifying system.

The mill consists of a sturdy cast, mill housing, and a rotor with a crosshead. The grinding roller travels on the rings, whose centrifugal action against the grinding ring reduces the minerals into finer sizes. Rotating shovels guide the particles from the mill bottom to the grinding zone. The air system then transports the ground particles to the classifier, where it rejects coarse particles and sends them back to the mill for further grinding. The speed of the classifier can be adjusted to meet the required particle size and distribution. Finally, a downstream collector receives the particles with the necessary final degree of fineness.

The Pendulum Mill PM can achieve narrow particle size distribution with an upper particle size ranging from 10 μm to 1,000 μm (1,250 to 18 mesh). The mill capacity ranges from 0.5 t/h to 150 t/h and can process up to 35% humidity material.

Grinding and drying of CaCO3

After crushing and drying mined bentonite, this clay mineral is usually processed through a grinding mill into powder form. To maximize the capability of bentonite powder in hydration and water absorption, a combined milling and drying system with a higher lifetime of wearing parts is required to achieve desired fineness and product quality.


<h2>Mill for grinding and drying soft to medium minerals</h2>
The Pendulum Mill PM by NEUMAN &amp; ESSER is a roller mill used for fine grinding and drying minerals such as bentonite, clay, limestone, and others. It combines grinding, de-agglomeration, drying and classifying, making it an extremely robust and durable design.

The mill consists of a sturdy cast, mill housing, and a rotor with a crosshead and pendulums whose rollers run against a grinding ring crushing the bentonite material into fine sizes. Air transports the materials to the grinding zone through channels and rotating shovels. Both fine and coarse particles enter the classifier, where it separates coarse particles and sends them back to the mill for further grinding. The classifier speed can be adjusted to meet the requirements that come with the desired particle size distribution. Finally, the downstream collector receives the particles with the required final degree of fineness.

The Pendulum Mill PM can achieve upper particle sizes ranging from 10 μm to 1,000 μm (1,250 to 18 mesh). The various mill capacities can receive input quantities ranging from 0.5 t/h to 150 t/h and process feed material moisture of up to 35%.

Grinding and drying of bentonite

Industrial drying machines are designed to remove moisture from your product. But the drying process must cater to variations in the state of matter and molecular structure of the input material. Industrial dryer technology exploits the modes of heat transfer (convection, conduction, radiation, evaporative cooling) to control the moisture content.

Drying

Drying and grinding can be an important feature when trying to process products such as raw and refined minerals, organic and inorganic chemicals, food ingredients and waste streams. It is crucial to maintain particle size and consistent quality of the finished product during such processes. You will need an efficient and abrasion resistant attrition solution to pulverise and dry your product into your required particle size.


<h2>A simplified process while drying and grinding ensuring high product quality</h2>
Atritor’s Dryer-Pulveriser is able to grind and dry the product simultaneously. It is an air-swept mill that uses an air stream to efficiently process the product and controls the final particle size. It is able to process feedstocks of up to 50+mm and production capacities from 100kg/h up to 30t/h with evaporation rates up to 6,000 kilograms per hour.

The mill acts as an efficient dryer when the process air is heated using a hot air generator or waste heat from another process. It can reach an inlet temperature of up to 550ºC. Heat energy from the process can be recovered from the heated air stream. After flash drying, the product is kept cool due to evaporative cooling. The output temperature of the product is maintained accordingly to control the moisture content of the product.

The Flash drying grinder for powders is configured with a combination of variable speed rotor, hammer arrangement and fixed pins. Turbulence inside the grinding area creates attrition to reduce the particle size, which can be controlled for simple deagglomeration of the product. An internal classifier configuration can also be used to further control particle size.

The ‘A’-series is constructed with internals that are resistant to abrasion for applications that can cause high amounts of wearing to the equipment. Where the desired amount of evaporation required far exceeds the grinding duty, the ‘B’-series machine of a lighter weight, fully fabricated configuration permitting higher airflows can be used for non-wearing product or duties, as well as for for applications in which stainless steel contact parts may be necessary.

Flash drying grinder for powders

Grinders use a spinning blade or rotating abrasive elements to reduce the size of various materials. The specifications, RPM and grit of the engineered grinder, will result in various particle sizes. As a result, what you want to make will determine the type of grinder you need. Grinding is used for improving the texture and flow properties of various products and to enhance the flavor of food products such as coffee, spices, sugar, nuts, sesame, poppy seeds, lentils, wheat, and rice. Choosing the right rotational speed, grinding elements, and processing power allow the grinding and shredding of a wide range of materials into coarse or fine powders. Popular types of heavy duty grinders in food processing include angle grinders, bench grinders and meat grinders.

Grinding

When you need to produce ultra-fine powders, the milling and drying process employed is what ensures the consistency of your product. To process minerals and chemicals, you need a machine which is powerful, flexible, simple to maintain.


<h2>Versatile and highly efficient milling and drying</h2>
Atritor’s cell mill has been constructed to produce ultra-fine powders. It is able to grind, flash dry, classify and surface coat powders at the same time. Its capacity ranges from 50 kilograms per hour to 15 tonnes per hour, with evaporation rates up to 3,000 kilograms per hour.

The feed can be dosed directly into the machine via a screw feeder or via the inlet air duct. It is then ground in a vertically mounted, multi-stage rotating rotor. Each of the rotor sections is constructed with up to 200 quick-change blades. There is also the possibility for a classifier which is mounted at the discharge section to ensure that oversized feed particles are either discarded or recirculated.

The mill acts as an efficient dryer when the process air is heated using a hot air generator or even waste heat from another process. It can reach an inlet temperature of up to 450ºC. Heat energy from the process can be recovered from the heated air stream and utilized to preheat the intake air. After flash drying, the product is kept cool due to evaporative cooling via the constant exposure of new surface areas of the product created during attrition.

In the case of minerals that require surface treatment, the cell mill provides a range of coatings and surface modifiers that can be added on the side of the machine during the milling process. It has a wide range of applications, from minerals like GCC, clay and limestone to chemicals, dyes, pigments and a wide range of food ingredients and by-products.

Pelleting equipment transforms powdered, mashed, or grounded material into a denser cylindrical shape. Pellet processing compresses the fine material against a perforated die, where it will be shaped and cut. Although granulating and extrusion also produce pellet-like products, manufacturing pellets is a distinct process.

Pelleting

Coffee bean separation is one of the important steps during bulk coffee production. In order to ensure that the coffee is pure, manufacturers must use industrial vibrating sieves to filter out the contamination. You need vibrating sieves, to remove various types of foreign and unwanted particles from their coffee so that when it reaches the final stage in the process line, all of the impurities have been removed, ensuring high quality.


<h2>Reduce product waste with a state-of-the-art sieve to filter your coffee beans</h2>

Dosing systems are a line of hoppers, feeders, filling machines, and checkweighers that operate in sync to dispense materials accurately. Dosing is an essential feature of the packaging process, whether you’re filling shampoo bottles or tea bags. But dosing equipment is critical for formulations, too, particularly in the pharmaceutical and chemical industries. Imprecise dosing may cause quality degradation in the best-case scenario. In the worst scenario, it creates serious health risks.

Dosing

For large scale production processes in the chemicals or food industries that require the coarse or fine screening of difficult materials, traditional sieves do not provide sufficient throughput. A high volume rectangular sieve can process large quantities consistently, and the addition of multifrequency vibration makes them capable of extremely high efficiency.


<h2>Specialist heavy-duty sieve for large scale industrial processes</h2>
