Description

Double-Layer Vibrating Grain Gravity Destoner is an efficient cleaning equipment specially designed for the grain processing industry. It is widely used in flour mills, moulins à riz, feed processing companies and seed selection and processing scenarios. This equipment uses the difference in specific gravity between grains and impurities, combined with vibration and airflow, to efficiently remove high-density impurities such as stones, glass, and metal mixed in raw grains. The double-layer screen structure combined with the vibration motor drive system allows it to maintain excellent stone removal effects while operating stably, with low noise and easy to operate. It is an ideal stone removal equipment in the modern food processing industry.

Grain Gravity Destoner Working Principle

This equipment operates based on the combined principles of gravity separation and suspension velocity difference.

The material is evenly distributed on the upper pre-separation screen surface via the feeding device. Under the combined action of the reciprocating oscillation motion of the double-layer vibrating screen and the airflow passing through the material layer from bottom to top, the material layer undergoes fluidization and stratification due to density differences—lighter grains float on the upper layer, while heavier impurities such as stones settle to the bottom layer and come into contact with the screen surface. Subsequently, the lower layer of material rich in impurities is conveyed to the lower destoning screen surface, where the stones and grains are finally separated by reverse airflow. The cleaned grains after destoning flow slowly towards the discharge port on the airflow cushion layer. To achieve the best separation effect, the screen inclination angle, airflow, and air pressure can all be flexibly adjusted according to the material characteristics.

Gravity Destoner Features

Double-layer vibrating screen structure:

The equipment is equipped with upper and lower screen layers—the upper pre-separation screen removes large impurities such as straw, while the lower destoning screen is specifically for stone separation.

Vibrating motor drive system:

Utilizing a vibrating motor as the driving force, the system features a compact structure, stable mechanical performance, and smooth and reliable operation.

Fully enclosed negative pressure suction system:

The equipment adopts a suction design and is equipped with a wind pressure display device, allowing for flexible adjustment of airflow and pressure within a wide range.

Adjustable screen tilt angle design:

The screen tilt angle can be adjusted within the range of 7-9 degrees to adapt to different materials and working conditions.

Gravity Grading Destoner Advantages

Exceptional destoning efficiency: Effectively removes stones similar in size to the grain, achieving a removal rate of over 99.5% and ensuring product purity.
