Elutriator

An Elutriator is vertical tube through which a fluid passes upwardly at a specific  velocity while a solid mixture, whose separation is desired, is fed into the top of the column. The large particles, which settle at a velocity higher than that of the rising fluid, are collected at the bottom of the column, and the smaller particles are carried out of the top of the column with the fluid. Several columns of different diameters in series may be used to bring about a further separation

Experimentation:

• To determine the velocity of water for the separation of equal sized particles of different densities.
• To determine the velocity of water for separating the given solid mixture of the same density on the basis of size

Utilities Required :

• Material for Feed.
• Water Supply and Drain.
• Electric Supply : Single phase, 220 V AC, 0.5 kW.
• Dryer
• Weighing Balance.
• Floor Area 1.5 m x 1 m.
