<h3>Use a rotary kiln calcium carbonate processing of limestone stock smaller than 40 millimeters</h3>
<p>Limestone is subjected to high temperatures to strip carbon dioxide and produce calcium oxide. This calcination process is performed in a kiln, but the type of technology depends on the <a href="https://www.eula.eu/about-lime-and-applications/production/kiln-types/" target="_blank" rel="noopener">feed size</a> of your raw material.</p>
<p>A shaft kiln typically handles limestone between 20 mm and 175 mm in size. Stones go through preheating, heating, and cooling as they travel down the shaft to discharge quicklime. A rotary kiln employs the same principle but is set at a horizontal position and tipped at an angle of around 4°. This structure accommodates finer stones in the 15 mm to 40 mm range.</p>


<p>Calcium oxide is hydrated to produce calcium hydroxide. Also known as slaked lime, this compound treats industrial wastewater and neutralizes gases.</p>
<p>Slaking temperature is critical to the structure of particles. If you heat the slurry to around the boiling point of water forms <a href="https://vessco.com/wp-content/uploads/2012/12/lime-slaking-process-hassibi-2009.pdf" target="_blank" rel="noopener">finer particles sizes</a> with a smaller specific surface. But unless mixed well, the particles will crystallize and agglomerate in the slurry.</p>


Mix calcium slurry constantly to avoid crystallization of particles

<p>Precipitated calcium carbonate (PPC) is synthetically produced from the chemical reaction between carbon dioxide and “milk-of-lime” slurry. The material is a refined form of limestone using calcium carbonate processing techniques.</p>
<p>The white material serves as a filler in different applications such as paints, papers, and pharmaceutical products. The grain size can be <a href="https://www.mineralstech.com/business-segments/specialty-minerals/paper-pcc/paper/precipitated-calcium-carbonate-(pcc)-pigments#:~:text=Albacar%C2%AE%20PCC%20ranges%20in,6%20to%2012%20m%C2%B2%2Fg." target="_blank" rel="noopener">controlled</a> from submicron to more than 10 microns, and the purity can be increased to 99.9%.</p>


Precipitated calcium carbonate can achieve 99.9% purity

<h3>Spongy form of calcium carbonate could open up new applications</h3>
<p>Researchers <a href="https://www.eurekalert.org/news-releases/658131" target="_blank" rel="noopener">stumbled upon</a> a spongy form of calcium carbonate occurring naturally in mussels.  Ground shells of the mollusc reacted to acetic acid to form a highly absorbent type of calcium carbonate.</p>
<p>The porous material can <a href="https://www.eurekalert.org/news-releases/658131" target="_blank" rel="noopener">soak up contaminants</a> like oils or dyes and is an object of interest for a range of biomedical applications.</p>

Let's make calcium carbonate

Calcium carbonate makes up almost one-twentieth of the earth’s crust. But the abundant mineral is found in many living things, including the human body. However, calcium carbonate processing extracts the multi-purpose material from inorganic sediments, namely limestone, chalk, and marble.

Calcium carbonate

The inventor of the lithium-ion battery predicted that solid-state batteries would become commercially available by the mid-2020s. This battery type promises a marked improvement in safety, power, and environmental impact compared to current battery packs. However, recent breakthroughs in the lab don’t automatically translate into mass production. The complex processing requires specially-designed manufacturing technology to make solid-state batteries a real solution.

Process

A ball mill uses the impact of metal or ceramic balls, falling from near the top of a horizontal shell to crush the material into fine particles. The outer cylindrical shell rotates to lift the grinding balls to the top from where they fall; grinding and blending the materials at the same time. Ball mills are typically used in the ceramic, glass, paint, pyrotechnics, and porcelain industries and are also often used in food and chocolate production. By choosing the right combination of rotational speed, ball material, size, and weight it is possible to process a wide range of materials to produce ultra-fine products

Ball mills

Continuous milling is a flow production method used to grind materials without interruption. It is often used in the production of foods, cosmetics, pharmaceuticals, chemicals, and minerals. The material to be processed flows in at one end and the milled output flows out at the other in a continuous process. By choosing the right combination of milling technology and processing power you can obtain the desired particle size distribution in an uninterrupted stream.

Separation process to separate components of a liquid mixture, for recovering dissolved solids from liquids. 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 are widely used in the pharmaceutical and chemical industries for the isolation of active ingredients and high purity chemicals.

Ceramics are defined as inorganic and non-metallic materials. In general, they are typically brittle, hard, and elastic as well as resistant to heat and corrosion; in fact, after shaping them into the desired shape, they are heated in an oven called kiln at very high temperatures (1,000 °C to 1,600 °C). Kaolinite and aluminum oxide are the best-known examples of ceramics.

Ceramics

Due to their potential hazardous nature, chemicals are classified for proper identification and safety during production. Chemical classification depends on their properties, structures and functions. In the chemical industry, you can regard them as basic chemicals such as acids, chemical products to produce plastic materials and finished chemicals for use in cosmetology. As a manufacturer or engineer, you want to know their reactivity when using chemical process equipment.

Chemicals

We carry dozens of metals around every day. The ubiquitous smartphone is built with no less than 20 metals, each with specific behaviors and purposes. Metals are a pervasive class of materials that have defined entire eras of human development. It is no exaggeration to say that metal production equipment is the core of our metallic world. But, paradoxically, this manufacturing technology itself is mainly made of metal.

The nearly 5,000 known minerals on earth share some characteristics to be classified as minerals – they are inorganic, solid, naturally occurring elements and have a particular chemical formula and an ordered internal geometric structure. However, minerals are not all the same. One way to divide them is based on their physical characteristics such as hardness, luster, color, and shape. For example, the diamonds we use to make jewelry are very hard minerals while talc is a soft mineral; gold is a shiny mineral while others are less so.

Minerals

solid

Bentonite is a clay derived from the alteration of volcanic ash. Bentonite is solid, so after extracting it from the deposits, it has to be crushed and dried to reduce its moisture content up to 15%.

Bentonite

Kaolin, also called china clay, is made from natural rock composed of aluminosilicate clay or kaolinite. Kaolin has wide applications in different industries. Moreover, their classification depends on their industrial use, which includes film formation, fiber extension, polymer extension and chemical composition. Choose a kaolin processing machine to help you make kaolin for beauty products, paper filler, coating, ceramics and even medicine.

Constant product quality and superior particle size distribution

High energy efficiency

High utilization and minimal downtime

Widely used in the construction industry as filling materials, calcium carbonate is usually made from pulverized limestones. As a result, vibration and noise are typical issues during CaCO3 powder production processes, especially during grinding. Therefore, it is essential to have a classifier milling system to ensure low noise and low vibration while achieving the maximum particle fineness required in CaCO3 powder production.


<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

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.

Classifier mills

Milling &amp; grinding technologies are used to reduce the particle size of your product while preserving its essential properties. The choice of a suitable solution depends on your product feed, desired particle size distribution as well as your production volume.

With consumerism comes great responsibility. More and more are switching their diet towards vegan and vegetarian alternatives, varying from dairy to meat. As more plant-based meat technologies are being invented, the production is rising in popularity. Ever wondered which challenges come with that?

Plant-based meat

Cheese is the most demanding food in the entire dairy family to emulate using non-animal ingredients. The complex physical and taste profiles of animal-derived milk products make plant-based cheese manufacturing challenging to pull off. But the growing appetite for lactose-free and non-dairy products is serving alternative platters of cheese.

There are two misconceptions about floating pellets. The first one is that they are made with a pellet mill, when the proper floating pellets-making machines are extruders. The second misconception is that floating feed is only used for fish. However, many other species consume feed on the water, such as crocodiles and birds.

Floating pellets

In aquafeed, you can find three types of pellets: floating pellets, sinking pellets, and slow-sinking pellets, because not all aquatic species eat at the same height of the water column. In the case of bottom feeders such as shrimp, river crab, sea bass, and some species of catfish, they eat sinking pellets. Contrary to tilapia and carp that feeds from the surface with floating pellets. Sinking pellets production must control water stability to preserve the quality and form of the pellets, avoiding nutrients' dissolution in the water.

Sinking pellets

When it comes to aquafeed, you can find three types of pellets: floating pellets, sinking pellets, and slow-sinking pellets. Not all aquatic species eat at the same height of the water column. For example, tilapia and carp eat at the surface (floating pellets) while shrimp and sea bass eat at the bottom (sinking pellets). Slow-sinking pellets are ideal for species that eat along the water column such as salmon and cod.  To get the pellets to sink at the right rate, slow sinking pellets production must control water stability in the products.

Crushing is the process of applying an amplified force to a material to break it down into smaller pieces. A crusher is a machine designed to crush large chunks of material into smaller bits or a powder. They are used to reduce mineral rocks to smaller rocks, gravel, or dust. They are also used to reduce the size of waste materials for easier disposal/recycling or to reduce the size of a solid mix of raw materials. Crusher selection depends on the physical properties of the material to be processed, the in-feed size, and the desired output particle size.
