High-efficient Destoner Machine Manufacturer and Supplier

destoner

The gravity classify destoner is a gravity separator used in the oil material cleaning of the seed processing plant. A high efficient and multi-functional seed cleaning equipment. Under the synthetic action of vibrating, sifting and the air -flow, it removes stones from the oil material. Our destoner designs with two layer of screen, which separate the heavy impurities and light impurities complete and efficiently. It features the optimized designing of the simple cleaning procedures and high clearing efficiency with double vibra-motors driving, balanced running.

Destoner

Destoner

The machine is designed for separating stones from a continuous product stream. On the basis of differences in specific gravity, reliable removal of high-density impurities such as stones and pieces of metal and glass is achieved. Versatile application in flour mills, rice mills, feed mils and seeds selection processing.

Features of the Destoner Machine

- Advanced design and excellent fabricating
- Reliable and excellent stone separation and efficient cleaning
- High specific capacity
- Easy operation and maintenance
- Two options: with or without air-recycling system.
- A fan is equipped on the air-recycling type and a special separator is installed ahead of the fan. The separator deflects the aspirated air through a lamellar system so that dust and chaff are separated from the air and discharged by an airlock valve while the cleaned air is recycled by the fan in the air return pipe to the destoner.

Working Principle of the Destoner Machine

- The sieve box which is normally equipped with two-layer sieves is supported by hollow rubber springs and is caused to oscillate by one or two vibrators depending on machine execution.
- The grain is spread by a feeder across the entire width of the machine, and then the product stream is stratified on the pre-separation screen according to its specific gravity by the oscillating motion of the screen and by the air flowing through the product from bottom to top. The light particles collect at the top, and the heavy ones including the stones at the bottom.
- The lower layer with the heavy particles flows upward and is fed to the final separation zone of the bottom de-stoning screen. Final separation of the stones from the grain is accomplished by a countercurrent of air.
- The stone-free product streams on the two screens float on cushions of air, flowing slowly toward the product outlet, and then are discharged through the squeezed rubber valves.
- To achieve the optimum degree of separation, the inclination of the screens, the air volume and final separation can be adjusted accordingly.
