The stone remover, also known as the grain destoner or impurity separator, is a device used to remove impurities such as stones and mud from grains. Its working principle mainly uses the difference in specific gravity between the material and the impurities to separate the impurities through the screen and water flow. The following is a detailed introduction to the working principle and structure of the stone remover:
Working principle
The material enters the stone remover from the feed port, and the impurities such as stones and mud are separated by the filtration of the screen. The specific gravity adjustment device controls the size and direction of the water flow to keep the material suspended in the water so as to better separate the impurities. The separated impurities are discharged through the discharge port, and the material is discharged from the other side of the stone remover.
Structural composition
Feed port: used to introduce materials into the stone remover, usually with an adjustable feed hopper to control the feed amount.
Screen: It is the core component of the stone remover, used to separate impurities in the material. The screen is usually made of materials such as stainless steel or nylon, and has a certain elasticity and wear resistance.
Specific gravity adjustment device: used to control the size and direction of water flow so that the material remains suspended in the water. The specific gravity adjustment device is usually implemented by solenoid valves or manual valves.
Discharge port: used to discharge the separated impurities, usually with an adjustable discharge hopper to control the discharge amount.
Drive device: used to drive the destoner to operate, usually with an electric motor or hydraulic motor. The drive device is usually installed at the bottom of the destoner and drives the screen to rotate through a belt or chain.
Use and maintenance
When using the rice destoner, regular inspection and maintenance are required to ensure the destoner effect and the normal operation of the equipment. At the same time, according to different materials and destoner requirements, the working parameters of the destoner need to be appropriately adjusted to achieve the best destoner effect.
By understanding the working principle and structure of the destoner, you can better use and maintain this equipment, thereby improving work efficiency and destoner effect.
