The rod mill is substantially the same as the ball mill, but there are three distinctive differences:
1. The rod mill is used as a steel rod having a diameter of 50-100 mm as a grinding medium, and the ball mill is used as a grinding medium. SteelThe rod length is 25-50 mm shorter than the cylinder, which is often used with a carbon 0.8% -1% high carbon steel; the amount of the rod is approximately 35% -45% of the effective volume of the rod mill, and when observed with the naked eye, the stickThe horizontal plane is about 100-200 m below the centerline of the cylinder.
2. The ratio of the length of the rod mill body and the diameter is generally 1.5-2.0, and the inner surface of the lining plate on the end cover should be a vertical plane. The purpose is to prevent and reduce the steel rod in the cylinderGenerate confusion, bending, and breaking to ensure that the steel rods are regularly moved.The length of the ball mill is smaller than the diameter, and the ratio in most cases is only slightly greater than 1.
3. The rod mill does not have a plaid mine, and an overflow type, open-shaped mine; the diameter of the hollow journal in the mineral end is generally larger than the same specification ball mill.The rod mill cylinder speed should be lower than the working speed of the same specification ball mill, so that the medium in which the medium is in the laxative state.
