Sand roller, also known as rice grinding wheel or sand grinding roller, is an important part of grain processing machinery, especially in the rice milling process plays a key role. It uses the friction on the surface of the sand roller to grind rice or rice to achieve the purpose of processing into refined rice.

The main material of the sand roller is usually high-hardness abrasive materials, such as special ceramics, quartz, cemented carbide, etc. These materials are wear-resistant and high-temperature resistant, which can ensure that the sand roller maintains a stable grinding effect during long-term and high-strength use. The surface of the sand roller is specially treated and has a fine grinding texture, which can uniformly and efficiently grind rice or rice to ensure the quality of the processed rice grains.

The working principle of the sand roller is mainly driven by a motor to make the sand roller rotate at a certain speed. When the rice or rice enters the grinding area of the sand roller, it is gradually ground and separated by the friction and extrusion of the sand roller. After grinding by the sand roller, the rice can be processed into refined rice, and the rice can be further refined to improve the taste and quality.

The performance and life of the sand roller have an important influence on the processing efficiency and product quality of the rice mill. High-quality sand rollers should have good wear resistance, impact resistance and stability, and can maintain stable grinding performance during long-term use. In addition, the maintenance and maintenance of the sand roller is also very important. Regular inspection and replacement of the severely worn sand roller can ensure the normal operation and processing effect of the rice mill.

In general, the sand roller is an indispensable part of grain processing machinery, and its quality and performance are directly related to the processing efficiency and product quality of the rice mill. Choosing the right sand roller and using and maintaining it correctly is of great significance to improve the efficiency of grain processing and product quality.
