Product Detail

Product Tags


Professional machine for removing bad and injured grains and seeds from good grains and good seeds.
The 5TB Gravity Separator it can remove blighted grains and seeds, budding grains and seed, damaged seed, injured seed, rotten seed, deteriorated seed, moldy seed, non-viable seed and shell from good grain, good pulses, good seeds, good sesame good wheat, barely, maize, all kinds of seeds.

By adjusting the wind pressure form bottom of gravity table and  the gravity table’s Vibration frequency it can work for different material.In the vibration and wind the bad seeds and broken seeds will move to bottom, Meanwhile the good seeds and grains will move from bottom to upper position, that’s why the gravity separator can separate the bad grains and seeds from the good grains and seeds.

Whole Structure of the Machine

It combines low speed no broken slope elevator, Stainless steel Gravity table, grain vibrating box, Frequency converter, brand motors, Japan Bearing
Low speed no broken slope elevator: Loading grains and seeds and beans to the gravity separator without any broken, Meanwhile it can recycling the mixed beans and grains to feed the gravity separator again
Stainless steel sieves: Used for food processing
Wood frame of gravity table : for supporting long time using and high efficient vibrating
Vibrating box :Increasing the output capacity
Frequency converter :Adjusting the vibrating frequency for suitable different material

Questions from clients

Why we need the gravity separator for cleaning ?

Nowadays, Every countries have higher and higher requirements for food exports.Some countries need to have a purity of 99.9%, In the other hand, If the sesame seeds and grains, and beans has higher purity, they will get higher price for selling in their market.As we known, the current situation is that We used the sample cleaning machine to clean up, but after cleaning, there are still some damaged seed, injured seed, rotten seed, deteriorated seed, moldy seed, non-viable seed existing in the grains and seeds.So we need to use the gravity separator to remove these impurities from the grain to improve the purity.

In generally, we will install the gravity separator after the pre-cleaner and Destoner, so that to get the high performance.
