Gravity grade destoner is mainly used for grading wheat, rice, peanuts, corn, soybean, etc., and removing stones, which can also be used for seed selecting. The machine has the characteristics of removing stones and sands according to classification, less energy consumption, no dust, lower noise, which can be operated and maintained conveniently. Use it together with independent ventilation system for better efficacy.

A1: This machine is mainly designed for grading and removing stones from wheat, rice, peanuts, corn, soybeans, and other similar grains. It can also be utilized for sorting seeds.
A2: The machine utilizes the differences in specific gravity between grains and stones. Through optimized vibration frequency, screen obliquity, and air flow pressure, it separates dense stones from lighter grains cleanly.
A3: The four corners are supported by high-quality imported rubber springs. This structure ensures stable and balanced vibration, reduces mechanical noise, minimizes wear and tear, and extends the overall service life of the machine.
A4: No, this destoner is designed to run with lower noise and generates minimal dust. For the best efficiency and clean environment, it is highly recommended to operate it together with an independent ventilation system.
A5: Yes, the vibration amplitude can be adjusted between 3-5mm, and the screen obliquity can be set between 5 to 9 degrees to match different grain types and production capacities.
