Remember these three points, let you simply distinguish between rod mill and ball mill

A lot of people come to our company to buy ball mill equipment, some of them do their homework in advance, basically need to know clearly have a certain knowledge and understanding, and some of them are professionals in the field, but there is also a small part of the customer is not particularly knowledgeable, this time in order to avoid being deceived, but also to find a way to find a professional accompanied by the purchase. But after all, we know ourselves, to be able to solve the fundamental, here we will give you a brief summary of the difference between rod mill and ball mill.

1, rod mill general diameter of about 50-100mm steel rods for grinding media, and ball mill steel balls for grinding media. The length of the steel ball is 25-50mm shorter than the cylinder, using high carbon steel manufacturing technology with a carbon content of 0.8%-1%; steel rods are loaded with about 35%-45% of the effective volume of the rod mill, observed with the naked eye, the level of the rod in the cylinder below the center line of the center line of about 100-200m.

2, rod mill cylinder length to diameter ratio of about 1.5-2.0, and the end cover of the inner surface of the liner should be vertical plane. The purpose is to reduce the steel rods in the cylinder body to produce chaotic movement, bending and breaking, to ensure that the steel rods have regular movement. The length and diameter of the cylinder of the ball mill are relatively small, and in most cases the ratio is only slightly more than 1.

3, the rod mill is not lattice plate discharge, but the overflow type, open type discharge; discharge end hollow journal diameter than the same specifications of the ball mill is larger. The rotational speed of rod mill cylinder is lower than that of ball mill of the same specification, so that the medium inside is working in a cascading state.
