Industrial Vibro Destoner Machine

Industrial Vibro Destoner Machine

An Industrial Vibro Destoner Machine is a high-efficiency grain cleaning and separation machine used in agro-processing units to remove stones, sand, glass, metal particles, and other heavier impurities from grains, seeds, pulses, spices, coffee, and other agro-products. It works on the principle of vibration and density difference, separating heavier contaminants from the lighter material as they pass over a perforated vibrating deck.

Indian manufacturers offer a wide range of vibrodestoners suited for small-scale mills to large industrial food processing plants. These machines are robust, energy-efficient, easy to maintain, and built for continuous operation in harsh conditions. They are critical in ensuring food safety, improving end-product quality, and protecting downstream machinery from damage.

Top 10 FAQs About Vibro Destoner Machines

What is the working principle of a vibro destoner?

It uses vibration and air suction to separate heavy contaminants based on density differences.

Which products can be cleaned using a destoner?

Rice, wheat, pulses, coffee beans, maize, millet, seeds, spices, and more.

What is the typical capacity range?

Ranges from 1 TPH to 15+ TPH, depending on model and grain type.

Can it remove both large stones and fine sand?

Yes, it efficiently removes large and fine heavy impurities.

What is the power requirement?

Usually between 0.5 HP to 5 HP, based on size and deck configuration.

Does it require compressed air or vacuum?

Most models use a built-in blower or suction fan—no external air supply required.

Can it be integrated into a modern grain cleaning line?

Yes, it is commonly installed before or after pre-cleaners and graders.

How do you adjust it for different grains?

Adjustable deck inclination, vibration frequency, and airflow settings allow customization.

Is it suitable for dusty environments?

Yes, with dust-free operation when connected to aspiration systems.

Is after-sales service available in India?

Most reputed Indian manufacturers offer full support including installation, AMC, and spares.
