Product Detail

Product Tags


Professional machine for removing stones from grains and rice and sesame seeds.
TBDS-7 / TBDS-10 blowing type gravity de stoner is to separate stones through adjusting wind, Larger proportion material stone will be moved from bottom to upper position on the gravity table, the final products such as grains, sesame seeds and beans will flow to the bottom of the gravity table.

Cleaning result

It consists of Bucket Elevator,  Air Screen, Vibrating box , Gravity Table and Back Half Screen .

Raw materialwith stones

Raw soya beans with stones

Final soyabeans

  Final soya beans without stones

Whole Structure of the Machine

It combines low speed no broken bucket elevator and stainless steel gravity table, wood frame, wind box, transducer, vibration motor and fans motor, Frequency converter for different grains, beans, sesame seed.
Bucket Elevator: Loading the cleaner, without any broken.
Stainless steel gravity table:Used for food processing.
Wood frame of gravity table : for supporting long time using and high efficient vibrating.
Wind box: for blowing the material to separate the stones and grains become two layers.
Frequency converter :Adjusting the vibrating frequency for suitable different material.

Questions from clients

What is the main function from gravity de-stoner machine ?
As we known in the agro grains processing flied, all the cleaner it is belong to pre-cleaning function, All the grains cleaner can remove 99% dust, light impurities and large impurities from the sesame and pulses, after cleaning there are still some stones existing in the material (stones which it is same size as the sesame and beans), It is very hard to remove them out from the raw material, so we need to use the especially stones remover machine to clean it.

The principle of gravity destoner, it is depend on the different weight between grains and stones, When the gravity destoner working the stones will go to high position on the gravity table, the grains, such as sesame, pulses will go to low position on the gravity table. That’s why they can be separated.
