Our Disc Mill is the crucial first step in your starch production line, expertly engineered for the wet milling process. This machine precisely crushes steeped corn kernels to efficiently release starch, gluten, and germ. Designed with robust, corrosion-resistant materials and precision-engineered milling discs, our Disc Mill guarantees exceptional grinding efficiency. This ensures you achieve optimal particle size, which is critical for maximizing your starch yield and ensuring the seamless operation of subsequent separation and purification systems.

The steeped corn kernels are fed into the center of the mill, where they are caught between the two discs. The high-speed rotation of the moving disc causes the kernels to be repeatedly impacted, crushed, and sheared against the stationary disc. This action breaks the kernels apart and grinds them into a fine, uniform slurry.
The gap between the discs is precisely adjustable. A wider gap results in a coarser grind, while a narrower gap produces a finer slurry. This control is crucial for optimizing the release of starch while minimizing damage to the corn germ, which is a valuable by-product. The resulting slurry, a mixture of starch, gluten, germ, and fiber, then flows out of the mill to be separated in subsequent stages.
