Industrial Mixer: Essential Mixing and Blending Equipment

Industrial mixer is a modern machine that mixes different materials and components to create the desired paste, solution, or mixture. It is used in popular industries involving chemicals, food, and drugs. Vital parts of this equipment are blades of different grades that produce mixtures of different levels of homogeneity.

Modern mixers perform industrial and chemical processes; like dry blending, paste mixing of viscous products, and emulsifying and homogenizing purposes. When it comes to scale, they are available from laboratory level to mass-production capacity.

Advantages of using Industrial Mixers

1. Work at the precise temperature and pressure

A major advantage of these industrial devices is that they mix and produce solutions while attaining the necessary temperature and pressure. Correct temperature is attained because of the presence of built-in heating systems.

2. Possess built-in features and options

Important options and features are also present in modern mixers, such as electric or pneumatic systems, CIP, spray nozzles, PLC systems. They are equipped with either hydraulic or electronic mechanism that ensures smooth start-and-stop operation.

3. Assure continuous mixing operation

Especially in the case of the latest models, mixing operations are done smoothly and continuously. Typical mixing equipment that produces smooth and consistent mixture is the Continuous Processor. With this machine, all ingredients are correctly measured and metered, with the desired solution being produced at the end of the process.

Most industries opt for machines that perform continuous mixing mainly for the following reasons; low consumption of electricity, greater control of operation, wider versatility, among many others. Another widely used continuous mixer is the twin-screw processor. This equipment has the capacity to deal with high mixture viscosity.

Different types of industrial mixers

1. Planetary mixer

Planetary type is used in mixing various commercial and industrial products such as food items, pharmaceutical products, adhesives, plastic, and pigments. Industries that require mixture of viscous-paste consistency achieved within a vacuum condition utilize this type of mixer. Paste production capacity varies, ranging from less than a pint to a maximum of 750 gallons.

2. Static mixer

This type of mixer, as the name implies, does not move. It possesses no movable components. The static type utilizes a specific chemical property of materials that’s necessary for mixing without the use of any pressure or force. Basically, as fluids are mixed in the machine, the right amount of air pressure is sealed within the unit. In effect, it creates a contained system that produces specific amount of pressure necessary in an environment. Such air pressure forces components and fluids to move and mix inside the machine.

Static mixers are used in gas refining and energy production, creation of fibers, blending of different chemical fluids, and proper management and disposal of wastewater materials.

3. High Viscosity Paste Mixer

A common industrial mixer is the high-viscosity paste mixer, which effectively combines solid and liquid materials. The end-product can be as little as a hundred thousand centipoise or as voluminous as a few million centipoise. Two important processes that involve this machine are vacuum and jacket, both of which are necessary steps in removing existing air and controlling the overall temperature of the mixture.

Metal Fabrication Processes and Equipment for Production of High Performance Products

Metal fabrication refers to the process of combined operations that are used to make something out of metal. The equipment used to perform the operations are: metal shears, laser cutting machines, water-jets, turret punches, machining centers, press brakes, rollers, and welding machines.The most commonly used types of metals are carbon steel, stainless steel, and aluminum. Most metal fabricators buy metal in the shapes of sheet, bar, and tubing to begin the fabrication process.

Metal sheets are used as a starting basis for a very large variety of metal products and can be purchased in a variety of gauges or thicknesses. When the thickness of the sheet is 3/16″ or greater, it is then referred to “plate”. Sheets are fabricated into thousands of different types of items such as industrial machinery, augers, conveyors, electronic enclosures, brackets, machine components, appliances, food processing equipment, just to name a few.

The first process of sheet metal fabrication is often to either shear, laser cut, or punch shapes into it. The equipment used to perform these steps is a metal shear, a laser, and a turret punch. Sometimes all three of these operations may be used while the metal is still in a flat shape. Once the basic flat shape is achieved, the metal goes to the press brake machines to make the bends. This process is called forming. Dies in a variety of shapes are used in the press brake to make one bend or a series of bends to form the metal as specified on the prints. At this point, some projects may be complete and can then be shipped to its end use, but often it goes to the welding tables next.

Welding is a true art in itself. It is the job of the welder to take a pile of cut and formed shapes, read the prints, then weld the metal pieces together for the final product. There is a plethora of welding techniques that can be used and it is important for the welder to use the appropriate procedure in order to get a good penetrating weld that will not fail. Welders must know how to deal with the expansion and shrinking of metal as it is heated during the welding process, then cools. Many metal fabrications, especially machine parts, have narrow tolerances that must be met. Fixtures are widely used by welders to help them quickly put the pieces together and hold them in the right place while they are welding them together.

Metal tubing and barstock is another common item purchased by metal fabricators. Railings and machine frames are two very common places that metal tubing and bar is used. Tubing is made in square, round, or rectangular shapes with a common wall thickness of about 1/8″, referred to by the industry as 10 or 11 gauge, or schedule 40 pipe. The reason metal tubing is commonly used is because it provides a lot strength with less metal than solid bar. Large tubing, 2-4 inches in diameter is used to fabricate railings that are installed along highway bridges where a very strong railing is needed should a vehicle crash into it. Using tubing as opposed to solid bar translates to less weight and lower cost, both desirable to the end user of metal fabrications. However, there are still many cases where solid bar is preferred. One case would be the shaft of a screw conveyor. There is extreme pressure applied by a motor to turn the auger and solid metal is necessary for successful operation of the screw conveyor. Many railings are also made of bar stock or made of a combination of bar and tubing. Bar is used on applications where the railing doesn’t have to be super heavy duty and thinner bars are desired.One half to 1 inch bar is widely used for railings in both residential and commercial purposes. Metal railings when made out of galvanized, painted, or stainless steel fabrication can be expected to last a lifetime with little to no maintenance.

Strength, low to no maintenance.Long lasting. That’s the beauty of metal. That’s why so many products are made with metal. Metal fabricators have the machinery and knowledge of how to take base metals that are melted and manufactured by steel factories, and turn them in to very useful products that can last a lifetime.
