Gravity Destoner
Product Type: Airflow-Based Density Separation & Destoning Equipment
When stones and heavy impurities are similar in size to your grains, standard cleaning equipment cannot remove them effectively. These contaminants can damage downstream equipment and reduce product quality.
This gravity destoner is designed to remove high-density impurities such as stones, sand, and mud lumps while also grading materials. It ensures cleaner output and safer processing across grains like wheat, corn, rice, soybeans, and seeds.
Product Features:
Removes same-size stones with high precision.
Dual-layer design for grading and destoning.
Stable airflow control for consistent performance.
Overview
In grain processing, removing stones—especially those with similar size to grains—is one of the most challenging tasks. Ineffective destoning leads to equipment wear, product contamination, and higher operational risks.
Shangke Machinery’s gravity destoner combines classification and destoning in one system, using controlled airflow and optimized screen design to achieve precise separation. With stable operation and easy adjustment, it helps you improve product quality while reducing maintenance issues.
Accurate removal of high-density and same-size impurities.
Dual-function system for grading and destoning.
Stable airflow with adjustable control.
