When materials need to be broken down, manufacturers use mixers. A mixer can be any machine that can blend, homogenize, or emulsify a various types of materials into a single substance. Mixers—also known as blenders—are capable of thoroughly combining any liquid or solid that a final product requires. The standard features of a mixer are a main chamber—which is usually a large vat or tank—with a motorized set of paddles or blades that rotate on an axis.
Depending on the application for which the mixer is used, it may have either a set of flat paddles or sharp blades. These attachments are usually removable in order to enable the mixer to work with as wide a variety of materials as possible. Most mixers are made from stainless steel, due to the material’s sanitary and corrosion-resistant nature. Other materials that may be used are aluminum, cast iron, steel, titanium, or thermoplastic. Mixers can be found most often during the processing or manufacturing stages of production, utilizing their powerful motorized blades to mix a variety of materials.
Industries such as adhesive and sealant, water treatment, automotive, pulp and paper, agricultural, chemical, pharmaceutical, and cosmetic use mixers to make their products. These products include polyurethane, silicone, petroleum products, toothpaste, hair products, detergent, shampoos, vitamins, lotions, creams, ointment, milk, syrups, medicines, dry and wet chemicals, biodiesel, and cement.
Industries that involve large-scale commercial production will most likely use industrial mixers, as they are capable of processing materials in large volumes. Industrial mixers consist of a large vat or tank to hold the materials, and blades that agitate the materials using force. One type of mixer is known as a paddle mixer, which is built with large paddles that rotate around a horizontal rotating axis.
Another type of mixer is a static mixer, which uses flat, thin, ribbon-shaped blades. These mixers get their name because they contain no moving parts. Instead, they contain strategically-designed blockages that forcefully blend the materials together. Static mixers are sanitary and easy to clean and maintain because of the simple arrangement of their blades. Read More…
In contrast to static mixers, high shear mixers are machines that operate at a high speed, and are designed to apply emulsification, disintegration, particle size reduction, dispersion, and homogenization to a variety of solid and liquid materials.
Drum mixers are a type of mixer that is built to blend low-to-medium-viscosity materials such as adhesives or cement. Drum mixers consist of gallon drums that rotate to mix the materials, and are capable or mixing substances of greatly varying particle sizes.
Certain mixers are used to give the final product a particular effect or appearance once mixed with certain materials. Food mixers are one example. They are commonly used to beat, knead, whip, blend, mix, or fold edible ingredients. Because of strict food and health regulations, these mixers must be sanitary.
Homogenizers are used to completely blend and break down materials. Industries such as science, technology and food processing have been using homogenizers for years. Milk and cream are familiar examples of edible products that are processed by homogenizers.
Emulsifiers are a high-velocity type of mixer that uses a perforated screen to mix materials that are otherwise highly difficult to blend.
Agitators are used to process substances with low viscosities such as liquids. The agitation process is mainly a process aid, acting as a secondary procedure in the overall process. and is not ideal to use for thicker, more viscous materials.
Batch mixers are used mainly to blend materials with varying lengths of mixing. To carry out this process, the mixers blend a single load of material, and are then refilled with the next material, or batch.
In many industries, mixers are crucial machines. Since mixing is often the first step in making a variety of products, they can be found in numerous businesses. Mixers are used very extensively in these processes, and deal with materials that must be thoroughly broken down and blended. Thus, they must be reliable and have an exceptional amount of durability.
Mixers must be assembled with precision and with high-quality materials in order for them to last as long as possible. Therefore, a high-quality manufacturing process must be implemented to ensure correct assembly of the machine. The materials used to construct the mixers must be carefully considered. Recommended materials are corrosion resistant and have a frictionless surface. It is possible to customize blenders, but they are not as commonly offered.
Custom-built and specialized machines enable their operators to have more control over the mixing process, which would wear down standard models more quickly. The design of the mixer is essential in ensuring optimal performance in the machine. Important factors to consider in engineering a mixer are the design of the blades and the power level of the motor. There are multiple companies that either recommend or require additional features for the mixer, including using high velocities to mix multiple materials, and ability to handle drastic drops in pressure.
