The origin of semi-autogenous mills
Thread Content
The use of semi-autogenous mills: These mills originated from autogenous mills. They generally have a relatively large diameter. Initially, the material itself was used to crush itself through collisions as the mill rotated; however, the impact forces in this process were low, resulting in poor crushing efficiency. Later, to improve the efficiency of semi-autogenous mills, a small amount of large-diameter steel balls (usually 120–150 MM in diameter) were added to enhance the crushing effect. Experiments have shown that a filling rate of 7–15% for these steel balls yields the best results. Depending on the actual size of the mill, the hardness of the material, and primarily the degree of oxidation of the material, the filling rate should be adjusted. It’s not true that the more the better, nor that the less the better; it should be determined based on the actual production conditions and requirements. Over the past 15 years, our company (Shandong Jinchi Steel Ball Heavy Industry Co., Ltd.) has been dedicated to providing customers with high-quality, cost-effective grinding products, ranging from steel balls to grinding materials such as grinding rods. Our company always adheres to the principle of serving every customer by creating value for them, solving their problems, and reducing the workload for their workers. Whether it’s bag wear or tonnage consumption, and regardless of whether it’s large or small clients, we put in 100% effort to serve our customers, and have earned their praise over the past 15 years. We welcome end-users and trading clients to visit our company for inspections and guidance.

This font is too large; everything is packed together, which looks unpleasant. Could it be changed?
