Commercial Automatic Stone Grinding Mill CE Certified Traditional Stone Mill for Grain and Flour Production

A stone mill is an ancient yet timeless milling device that utilizes a pair of circular millstones to process whole grains, nuts, and seeds into flour or pastes through a crushing and shearing action. Its fundamental principle has remained largely unchanged for millennia, prized for its ability to produce exceptionally high-quality, nutritious, and flavorful products. The core components of a stone mill are the millstones. Traditionally, these are carved from natural materials like granite or basalt, chosen for their hardness and natural, slightly porous texture. One stone is fixed (the bedstone), while the other rotates above it (the runner stone). The facing sides of both stones are engraved with a patterned series of grooves called furrows and flat areas called lands. These patterns are critical: they act as channels to draw raw grain into the center and distribute it evenly across the grinding surface, while the sharp edges of the lands perform the actual cutting and crushing. The process begins when whole grain is fed into the eye, a central hole in the runner stone. As the runner stone rotates—either by hand, water power, or in modern applications, an electric motor—the centrifugal force moves the grain outward between the stones. The grain is progressively ground finer and finer as it travels from the center to the periphery. The final product—flour—exits from the circumference of the stones. A critical feature of adjustable stone mills is the ability to precisely control the gap between the stones, allowing the operator to produce everything from coarse cracked grain to extremely fine flour in a single pass. They are engineered for commercial use, with robust frames, hoppers, and motors, making them a versatile tool that marries ancient wisdom with modern reliability for both small-scale artisans and large-scale commercial producers.
