MCQ on Industrial centrifuge


An industrial centrifuge is a machine used to separate liquids and solids by spinning them at high speeds. Industrial centrifuges are used in a variety of industries, including chemical, pharmaceutical, food processing, and oil and gas, to separate and purify substances.

There are many different types of industrial centrifuges, including decanter centrifuges, basket centrifuges, disk centrifuges, and sedimenting centrifuges. These centrifuges vary in size, design, and function, and can be used to separate a wide range of materials, including liquids, gases, and solids.

Industrial centrifuges work by spinning the material being separated at high speeds, using centrifugal force to separate the different components. The heavier components will tend to settle to the bottom of the centrifuge, while the lighter components will remain suspended in the liquid. The separated components can then be collected and further processed or purified as needed.


Industrial centrifuges are an important tool in many industries, and are used to improve the efficiency and purity of processes and products.
