SEED DESILTING GRAVITY SEPARATOR MACHINE

Introduction

Gravity separation is an industrial method of separating two components, either a suspension, or dry granular mixture where separating the components with gravity is sufficiently practical: i.e. the components of the mixture have different specific weight. All of the gravitational methods are common in the sense that they all use gravity as the dominant force.

Gravity Separation tables are used for the removal of impurities, admixture, insect damage and immature kernels from the following examples: Wheat, Barley, Oilseed Rape, Peas, Beans, Cocoa Beans, Linseed. They can be used to separate and standardize coffee beans, cocoa beans, peanuts, corn, peas, rice, wheat, sesame and other food grains.

Literature review

Gravity separation is one of the oldest techniues used by humans for separation process. It is mostly common in field of  minerals processing and purifying.

Gravity separation works on the fact of difference in density between various materials. Gravity separators, or air tables, separate particles with very close specific gravities. The materials with different specific gravity settles at different level in a mixture. That fact can be utilized to separate various mixtures of agricultural products along with wastes.

The particles are fed onto a large, slotted deck that is tilted slightly, as shown here. The deck vibrates and fans force air upward. Denser particles travel to the high side of the deck, while lighter particles roll off the low side
