Rice Destoning Machine

The stone remover, also known as the grain stone remover or impurity separator, is a machine used to remove impurities such as stones and mud from grains. Its working principle is to use the difference in specific gravity between the material and the impurities to separate the impurities through the action of the screen. The main structure of the rice destoning machine includes the feed port, screen, specific gravity adjustment device, discharge port, drive device, etc.

The material enters the rice destoning machine from the feed port, and the impurities such as stones and mud in the material are separated by the filtering action of the screen. The specific gravity adjustment device can better separate the impurities, and the separated impurities are discharged through the discharge port, and the material is discharged from the other side of the stone remover.

The main structure of the rice destoning machine includes the feed port, screen, specific gravity adjustment device, discharge port, drive device, etc.

1. Feed port used to introduce the material into the rice destoning machine, usually with an adjustable feed hopper to control the feed amount.
2. Screen: It is the core component of the stone remover and is used to separate impurities from the material. The screen is usually made of stainless steel or nylon, which has certain elasticity and wear resistance.
3. Specific gravity adjustment device used to control the size and direction flow to keep the material suspended in the water. The specific gravity adjustment device is usually implemented by solenoid valves or manual valves.
4. Discharge port used to discharge the separated impurities, usually with an adjustable discharge hopper to control the discharge amount.
5. Drive device used to drive the destoner to operate, usually by electric motors or hydraulic motors. The drive device is usually installed at the bottom of the rice destoning machine, and drives the screen to rotate by belts or chains.
