Concrete pan mixers are power-operated machines to blend raw materials such as sand, cement, grit, fly ash, aggregates, etc. to prepare a homogeneous concrete. They contain rotating blades or rollers within a stationary pan-like container to mix the raw material.
Cement mixers with a mixing volume of 110 litres will take half a bag of cement per mix; those with a mixing volume of 140–180 litres will take one bag, and so on.
Laboratory mixers are commonly used for the purpose of mixing or agitating lab samples.A magnetic stirrer involves a rotating magnetic field resulting in liquid to spin rapidly causing a stirring action.
Concrete mixers are devices capable of preparing concrete mixtures of varying strength precisely as well as quickly. Some concrete mixers are even capable of dispensing the concrete mixture directly on the location of the construction
