Metal filtration

Aluminium oxide or alumina is a naturally occurring compound of aluminium and oxygen made from bauxite, a dull and earthy rock with high aluminium content. Bauxite is the most common ore of aluminium and you can find it in tropical areas Most of the bauxite mined end up producing aluminium with specific aluminium oxide equipment. Statistics have shown that Australia and Guinea have the largest bauxite deposits in the world. Countries like China, Brazil, and India also have a large amount of the rock.

Landline telephones in the 1980s were minimalist gadgets that kept getting slimmer in the 1990s. In contrast, cell phones in the same period were bulky and cumbersome. And once they lost their charge, they turned into a giant paperweight. Then came a revolution in batteries and automation with lithium-ion battery manufacturing equipment. Mobile phones packed more power, recharged faster, and endured more recharge cycles. Above all, they were light and small, making cell phones the inseparable companions they are today. But Lithium-ion batteries power much more than phones. As a result, the world is seeing steady growth in battery manufacturing equipment and lithium-ion production lines.

Forged metal objects appear seamless, simple items. But as the use of metals changed over time and constructions became more intricate with additive manufacturing, a new way of processing materials surfaced. Metal powder manufacturing replaces the classic blacksmithing techniques, reducing scrap waste in the meantime. The final metal products, however, retain that shiny allure of the archetypal metal pieces.

Brewers' grain, also known as brewers' spent grain or BSG, is the residue of malt and beer production. This brewing by-product is sometimes wasted causing an important environmental impact, nevertheless, with the circular economy in mind, brewers' grain processing can turn waste into value mainly for the feed and food industry, tackling some of the sustainable development goals (SDGs).

Growing populations and intensive farming in the last centuries reduced soil nitrate levels. Aware of the risks to food security, chemists Fritz Haber and Carl Bosch developed a way to industrialize synthetic nitrogen fertilizer production. They created the Haber-Bosch process for ammonia synthesis which is still used today. Manufacturers produce over a hundred million metric tons of nitrogenous fertilizers every year.

You can separate liquids and solids in semifluid materials with a filter press. This machine may be automatic or manual, and passes the viscous substance through a series of filter chambers that press against one another to squeeze out the liquids, draining them in a channel at the base of the structure. The liquids are extracted using pressurized air, leaving only the solids to be collected from between the movable plates.

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 processing equipment.

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 processing 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.

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.

The inventor of the lithium-ion battery predicted that solid-state batteries would become commercially available by the mid-2020s, making them an attractive option for energy storage in a wide range of applications, including electric vehicles. This battery type promises a marked improvement in safety, power, and environmental impact compared to current battery packs that use a liquid electrolyte. 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, especially for the automotive industry.

The battery revolution is as old as the industrial revolution. But batteries only emerged as a viable power source with lithium-ion solutions in the last quarter of the 20<sup>th</sup> century. Today, anything from power tools to automobiles runs on batteries, but advances in battery making equipment are eyeing more ambitious undertakings. Will we ever see battery-powered container ships? Will Battery Energy Storage Systems grow grid-scale successfully? Production technology is steadily moving towards this vision.

Colors present an enduring philosophical problem that generates lofty debates about subjectivism and consciousness. Meanwhile, ink manufacturing equipment turns colors into physical objects. Perhaps paradoxically, digitalization keeps fueling the use of printing ink. From custom clothing to secondary packaging to aircraft livery, inks are everywhere. Indeed, philosophical discussions are also primarily conducted in ink on paper.

Dyes lend color to the things we consume. The foods we eat, the clothes we wear, and even the keyrings that separate your bunch all have a splash of dye added. Historically, colors were extracted from the natural world, but that process has been replaced by processing technology. Dye manufacturing equipment produces colors that are high in definition and consistency.

Despite only one letter difference, silicon and silicone are two different things. While silicon is the 14th chemical element on the periodic table, silicone is a synthetic material that, among other chemical elements, contains silicon. Although commonly observed as plastic, technically silicone is rubber. Among others, silicone processing equipment mainly involves several high-temperature machines, mixers and molds.

Vitamin C is an essential nutrient, but the human species lost the ability to produce it biologically during the course of evolution. Instead, we source the substance either from whole foods or vitamin C manufacturing. The chemical characteristics of the natural nutrient and processed compound are the same, but supplements offer higher concentrations, especially to persons with nutrient deficiencies.

As traced back to the first half of the 19th century, attempts at synthetic rubber production were simply to reproduce the original material due to the rubber shortage following World War II. Synthetic rubber production processes differentiate between producing the rubber, which can be done via solution polymerization and emulsion polymerization and creating the final product with the help of techniques such as molding and vulcanization.

Meat and bone meal production is used in pet food and animal feed, but the risks of mad cow disease make it unsuitable for ruminant feed. Bone meal and meat meal are by-products from slaughterhouses and livestock farms. They can come as separate meals or mixed into meat and bone meal (MBM) which offers more nutrients and increases amino acids in animal feed formulations. But besides feed, MBM can also be used as fertilizer and fuel.

Ceramics are defined as inorganic and non-metallic materials. Tthey 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.

<h3>Reduce the metal ore with a reactive agent to separate it from impurities</h3>
Smelting is an ancient craft that has continued to develop with new metal manufacturing equipment. Treat the ore to high thermal pressure in a blast furnace until the heat exceeds the melting point of the metal.

Add a reducing agent such as coke to strip away the oxides in materials and separate the metals from rock and gangue. The coke <a href="https://www.sciencedirect.com/science/article/pii/B9780080450513000075" target="_blank" rel="noopener">reacts with oxide</a> and splits it into carbon dioxide and metallic content.

The molten metal is channeled out of the furnace and deposited in molds. Allow the material to cool down and solidify into casts.

The <a href="https://sites.esm.psu.edu/courses/emch13d/design/design-tech/manufacturing/manuf_2.html" target="_blank" rel="noopener">two main types of mold casting</a> are expendable casts and permanent casts. The former class needs to be broken to release the cast metal, while the latter type is fabricated out of ductile material and can be reused.

Cast the molten metal to form an ingot

Metal deformation <a href="https://www.doitpoms.ac.uk/tlplib/metal-forming-2/printall.php#:~:text=A%20forming%20operation%20is%20one,yield%20stress%20of%20the%20material." target="_blank" rel="noopener">prepares the material</a> for the intended industrial application. One method for bulk deformation is rolling the metal to reduce it to a uniform thickness and smoothen the surface.

Extrusion and drawing are more suitable for alloys. The blend of metals is moved through a die opening by a ram. In the case of extrusion, no tensile forces are exerted, and the material is pushed out. On the contrary, drawing applies tensile force and pulls the metal out of the opening.

Finish metals for bulk manufacturing with the deformation process

<h3>Manufacturing metal powder from the ore</h3>
An alternative way to finish metal for further production is to <a href="https://making.com/metal-powder" target="_blank" rel="noopener">process it into powder</a>. The atomization technique passes the molten metal through a narrow opening against a jet of air or liquid.

The pressure causes the liquid metal to split into droplets, quickly turning into solids as the temperature decreases.
