Stirrers, mixers, agitators and a variety of other mixing equipment are used to process and manufacture chemicals and various pharmaceuticals. These devices can be designed to handle anything from minute amounts of ingredients or to agitate and mix large tanks, drums and vats. The type of chemical mixer necessary depends on the numerous factors, such as the materials being mixed, the amount of material being processed, the temperatures and consistencies involved, and the desired end product.

Types of mixing equipment include impelling devices, handheld mixers, portable mixers, lab stirrers, dispersion blades, tank mixers, static mixers and agitators. Impelling devices are typically used for a wide range of liquids, and use a rotating propeller, turbine, hydrofoil or similar impeller to create various flow levels in the processed liquid. Handheld mixers generally employ an impeller, as well, although it is often a more complex shape than a standard propeller or hydrofoil. Dispersion blades, which are resemble modified circular saw blades, cut through the solution being mixed, dispersing large particles, clumps and sludge. Bulk agitators are regularly employed for viscous fluids and custom mixing applications. Lab stirrers are used for precision mixing operations, often for research, experimentation and production purposes. Tank mixers are designed to handle a large volume of liquid for prolonged periods. Mixing devices are generally powered by an electric, hydraulic or pneumatic source.

Various continuous mixing machines are also employed by manufacturers. These devices are used to produce a wide range of chemical solutions, including adhesives, sealants, battery paste, coatings and pigments. Continuous mixers are also used in numerous food processing applications, from candy and cheese production to the kneading of dough. Generally, these devices include a feed inlet, a discharge outlet, and a motor. The motor propels the processing blades or screw and drives the solution through the machine, eventually ejecting it in the desired form.
