A Multitude Of Mixers
The main purpose of an industrial mixer is to serve as a
catalyst for combining different substances or stirring settled materials. Most
products that consumers utilize for everyday purposes, such as food or
shampoos, are manufactured through the use of a mixer. Mixing devices are also
commonly employed in laboratory settings for agitating chemicals and creating
fused solutions. One of the biggest advantages regarding industrial mixers is the
consistency of output. Mixer design has improved over the years to ensure that
materials are thoroughly combined. Some mixers are designed with the blades to
be the one of the only moving parts while other mixers use stationary blades
while the whole container rotates. Manufacturers have even created different styles
of blades that have higher performances based on the material it is mixing.
Mixers range from as small as portable food processors to as
large as mixers that stir 55-gallon barrels. There are several types of
industrial mixers including: ribbon, high sheer, paddle and more. Certain
mixers are specialized for particular applications. These applications usually
have broken down their processes into an exact science based on required ingredients.
High shear mixers are ideal for industries such as pharmaceuticals, paper
manufacturing, food preparation, cosmetic manufacturing and more. This style of
mixer is known for processes called homogenization, emulsification,
disintegration and dispersion. Manufacturers create mixers with various
features that allow for different speeds which results in higher levels of
versatility. Drum mixers are great for blending compounds that consist of very
different particle sizes such as cement. Since there is so much customizability
in the mixing industry, manufacturers will assist customers with determining
which mixers are best for the situation.
Mixers are machines that blend, homogenize, emulsify or otherwise mix
materials and substances into a single substance. They thoroughly
combine virtually any solid or liquid that is necessary to form a final
product. Though mixers vary by size and design, the majority consists of
large tanks or vats with motorized blades or paddles that rotate on a
Mixers, depending on the application, may have sharp blades or large flat paddles. The attachments or heads are generally removable to maximize the mixer's effectiveness with different materials. Mixers are most commonly constructed out of stainless steel because of its desirable sanitary and corrosion-resistant properties. Some mixers are made from thermoplastic, titanium, steel, cast iron or aluminum. Mixers are used throughout many industries during the manufacturing or processing period. Their powerful motors and blades allow mixers to work with a wide range of materials. These machines are widely used across many industries including the cosmetic, pharmaceutical, chemical, agricultural, pulp and paper, automotive, water treatment, adhesive and sealant industries to process toothpaste, glue, petroleum products, cement, biodiesel, dry and wet chemicals, medicines, syrups, beverages such as milk, medical ointment, lotions, creams, vitamins, shampoos, detergents, toothpaste, hair dye, petroleum products, silicone, adhesives, polyurethane and many other products or ingredients.
When a mixer is used for large-scale commercial production, it is most likely an industrial mixer because these mixers can process large amounts of materials. They usually have large tanks or vats to hold the substances as they are being mixed by mixing blades, the part of the agitator that imparts force to the material being mixed. Within the category of industrial mixers there are many variations. Paddle mixers are constructed around a horizontal rotating axis with broad shearing paddles radiating from spokes around the axis. Ribbon shaped mixing blades are flat and thin and are used in static mixers. These mixers do not have any moving parts and instead use carefully designed obstructions to force the flow of material to mix and blend together. Because of the simple arrangement of stationary blades inside, static mixers are sanitary and easy to clean. High shear mixers are quite the opposite; these high-speed machines offer homogenization, emulsification, disintegration, particle size reduction and dispersion for many different solid and liquid materials. Another variation of mixers is drum mixers, gallon drums that use the drum's rotation to mix materials. Drum mixers are generally used to blend mixtures of low to medium viscosities such as cement or adhesive slurries; this particular kind of mixer is capable of mixing substances of very different particle sizes.
There are also very specific kinds of mixers that are used with certain materials or to product a certain effect. Food mixers blend, mix, fold, whip, beat or knead multiple edible ingredients in food manufacturing processes. These mixers must meet certain regulations and be completely sanitary. For a breakdown and complete blending of a material, a homogenizer is used. Homogenizers have been used for a number of years in many industries, including science and technology, food processing and in some industrial mixing processes. A pair of common products that are homogenized is milk and cream. By using a perforated screen and high velocities, emulsifiers are able are able to thoroughly mix substances that are generally unblendable. For substances with low viscosities, agitators are used. Agitators are basically process aids because their main functions are secondary to the larger process. Agitators are used mainly in liquids, as agitation is not as effective with thick, highly viscous materials. For material that requires variable lengths of mixing, batch mixers are commonly used. These mixers work with a single load of material at a time before being refilled with another. When materials need to be broken down into smaller pieces, blenders are chosen for their sharp blades and high speeds. The terms "blender" and "mixer" are frequently used interchangeably.
Mixers are an integral part of many industries. Many companies rely on their correct function because mixing is often a first step for products that require further processing. These essential machines must be reliable and durable because certain materials may take a long time to be mixed thoroughly. Improvements in the manufacturing process help mixers perform better for longer periods of time. Because the parts of a mixer can be machined and assembled with precision and with quality materials, they tend to perform better and last longer. The materials that are used to construct mixers are chosen for certain attributes such as corrosion resistance or near-frictionless surfaces. Customized mixers are available though they are not widely offered. Specialty machines are able to perform to exact specifications which allows operators to better control the mixing process without causing excess wear and tear on other general models. The engineering of the mixer also has a role. The placement of the paddles, the design of the blades or the power of the motor are important factors for the engineer to consider. Additionally, companies must determine what additional characteristics they require. For example, some mixers are used to provide significant pressure drops while others are capable of handling large particles moving at high velocities.
