Sand roller, also known as grinding wheel or sand grinding roller, is a rice milling tool that uses the friction of the mortar surface to grind rice grains. Its main material is usually made of natural mineral stone such as granite and quartz, so the surface is fine and smooth and has a long service life. The sand roller is characterized by smooth grinding surface, slow speed, low temperature, and less damage to rice nutrients and fragrance. The rice grains milled by the sand roller have good taste and are not easy to deteriorate, which is suitable for the production of high quality rice and rice flour products.

The working principle of the sand roller rice mill is to use pressure and friction to grind rice into rice flour. When the motor is started, the sand roller is driven to rotate by the belt, and the grindstone or grinding head on the surface of the sand roller grinds the rice. Due to the small gap inside the sand roller, the rice grains are constantly pinched and rubbed inside the sand roller, and gradually ground into rice flour under the action of friction. Rice flour with different particle sizes is screened through a special screen and divided into different specifications for subsequent processing.

In addition, the sand roller rice mill is also equipped with a grain breaking device for breaking or separating rice husk, and a molecular sieve and a bran tube for separating broken rice and unbroken rice husk, respectively, and collecting and discharging the separated rice husk. The motor and transmission system are used to drive the sand roller and control the entire rice milling process. The control panel is used to control the start and stop of the motor, adjust the speed of the sand roller and other parameters of the rice milling process.

For users, the correct adjustment of the sand roller spacing is also the key to ensure the effect of rice milling. The distance between the grinding rollers can be adjusted according to the rice species and the degree of processing. The smaller the distance, the finer the processed rice grains. At the same time, cleaning the machine in time after use can extend the service life of the machine and ensure the quality of the rice.

In general, sand rollers are an important tool in food processing, especially in the production of high quality rice and rice flour products. For more information on sand rollers, it is recommended to consult the technical manuals of the relevant food processing equipment or consult a professional.
