TBDS-7 Destoner

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.

Stones removing rate above 99%;

Destoner can be used for all kinds of different grain and seeds,like sesame,soybean,beans,wheat,maize etc.

Unlike ordinary screening machines that separate seeds by size, the de-stoner separates stones and seeds by weight. After the pre-cleaner ( air screen cleaner or air screen cleaner with gravity table ) , The most of the dust , light impurities , big and small impurities have been removed . then left the seeds almost same size . and the stone /sand almost same size .

Given the same volume, the volumes of seeds and stones are different. There are several fans at the bottom of the de-stoner,  which blow strong air upwards when it is working. The de-stoner table have Stainless steel woven mesh on the top , which will let the air go through but stop the seeds drop .  When the air comes , it will blow the seeds up . because the seeds is light , it will be blow to higher position . The stone is heavy , it will stay on the destoner table .

Due to the combined effects of friction and vibration, the stones will be transported to the higher end of the de-stoner . The seeds at high places will automatically flow to the lower end of the destoner because they are in a suspended state.

According to the above working principle, the de-stoner can separate stones, sand and other impurities from seeds very well. However, it is worth noting that impurities such as soil lumps, cement lumps, etc. that are similar in weight to seeds cannot be removed well.

Our de-stoner has the characteristics of large capacity, high purity, stable operation and simple operation. In addition, the stainless steel table makes it very durable , Can be used for a variety of different seeds.

Structures

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.
