The mill is a type of machine designed for grinding hard materials into small pieces. There are various types of mills that are used to grind various types of materials. Previously, the mills were controlled manually, animals, water and wind. Currently, they are also powered by electricity. Below are the different types of mills.
Ball mill
Ball mill is a common type of mill. It has a horizontal, slightly folded cylinder filled with balls of metal or stone. These balls crush materials by blows and friction with rolling balls. Ball mills have a large length and small diameter and have a length of from 1.5 to 2.5 diameters. Often, ball mills are used to produce cement and process minerals. The diameter of industrial ball mills is 24 feet, and the motors are 22 MW. However, small versions can be seen in laboratories.
Kernel
In rod mills, a rotating drum causes loss and friction between the ore particles and the steel rods. Ball mills are more often used than rod mills for grinding minerals.
The rods installed in the machine are made of high carbon steel, and these rods have a diameter and length. If the machine has small grinding rods, it will have a large surface area, which will increase efficiency.
Autogenous mill
Autogenous mills are characterized by self-cleaning ore. In this machine, the drum rotates and throws large ore rocks into a cascade movement, which causes the breakage of large stones and the grinding of small particles. This type of machine does not have steel balls.
SAG Mill
SAG means semi-autogenous grinding. Like ball mills, these machines also have grinding balls in them. In fact, the SAG mill is used as a basic grinding solution. It comes with a 28 MW motor and a diameter of 44 inches. In fact, these machines are used in platinum, copper and gold mines. In addition, they are also used in various industries, such as lead, nickel, alumina, zinc and silver, and these are just some of them.
Pebble mill
In pebble mills, the drum spins rapidly and causes loss and friction between the ore particles and the stone stones. They are used to avoid contamination of products with iron from steel balls. Silica and quartz are commonly used because of their low cost.
Thus, it was an introduction to various types of mills. You can buy it based on your grinding needs. I hope the article will facilitate your choice.
