The ball mill is a tumbling mill that uses steel balls as grinding media. Ball mills can be used in wet or dry systems for bulk and continuous milling, and are most widely used in small or large-scale beneficiation plant.The feed can be dry with a water content of less than 3% to minimize the coverage of the ball, or it can be a slurry with a water content of 20-40%. The ball mill can be used for primary or secondary grinding applications. In the primary application, they receive feed from the crusher, and in the secondary application, they receive feed from the rod mill, autogenous mill or semi-autogenous mill.
Main partsThe mill includes motor, reducer, slow drive, power distribution control cabinet, feeding device, main bearing, rotary part, discharging device, transmission part, lubrication system (mainly including high-pressure pump station and low-pressure thin oil station) and other parts.The main working part of the ball mill is a rotary cylinder mounted on two large bearings and placed horizontally. The cylinder body is divided into several compartments by a partition plate, and a certain shape and size of grinding body is installed in each compartment. The grinding bodies are generally steel balls, steel forgings, steel rods, pebbles, gravel and porcelain balls. In order to prevent the barrel from being worn, a liner is installed on the wall of the barrel. The length of a cylindrical shell is usually 11.5 times the diameter of the shell.The grinding elements including grinding media and material in the ball mill move at different speeds. Therefore, the collision force, direction and kinetic energy between two or more elements vary greatly in the ball charge. Friction and wear or friction and collision energy all act on the particles. These forces come from the rotating motion of the ball and the particle motion in the mill and the contact area of the collision ball.

Since most of the gold mines contain impurities, we only can obtain the gold concentrate after a series of steps such as crushing, grinding, and sieving. The ball mill plays an important role in the gold ore grinding process, as a kind of high-efficiency fine grinding equipment, it has been widely used in fine grinding and ultra-fine grinding operations in mining, chemical, new materials, building materials and other fields. In the gold mining plant, the ball mill usually set after the jaw crusher, in a second-stage grinding, process sulfur-containing arsenic-containing refractory gold ore, and tailings treatment. The outstanding advantages of gold ball mill are low energy consumption, ultra-fine grinding, simple foundation, low noise and vibration, and has been regarded as an efficient new fine grinding equipment.
The main parts of the gold ore ball mill includes the feeding, the supporting device, the rotating part, the unloading device and the transmission device. Working principle: gold ore ball mill is a low-speed rotary cylinder horizontally mounted on the bearing. In the rotary cylinder, there are heavy steel balls. Along the motor and gear rotates the cylinder, generating centrifugal force to bring the steel ball to a certain height and then falling. The ore material are gradually crushed and ground by the steel ball impact force. The material is subjected to impact crushing and grinding, and the material is slowly flowed from the feeding end to the discharging end by the material level difference, until the material is discharged. That is the overflow ball mill.
Gold ore ball mill is especially suitable for two-stage grinding or ultra-fine grinding because of its advantages of ultra-fine grinding, high efficiency and energy-saving, low installation cost and low wear.
A gold mine used the JXSC gold ore ball mill for the second stage grinding to technically transform the original process, and achieved good results. After the transformation, the production capacity reached 130~140t/d. The production results show that the JXSC gold mine ball mill has low electromechanical consumption, high grinding efficiency, low wear of wearing parts and vibration noise less than 85dB.
There are rich sulfur-bearing and arsenic-containing refractory gold ore resources, but due to the lack of practical technology, these gold resources are not fully utilized. The JXSC Gold Mining Ball Mill has two basic characteristics of ultra-fine grinding and enhanced chemical leaching. The use of ultra-fine grinding of the JXSC gold ore ball mill can strengthen the alkali leaching, which may provide a technically feasible and economically reasonable treatment process for some sulfur-containing and arsenic-containing refractory gold ores.
Ball mill superfine grinding for secondary utilization of gold-bearing tailings in which gold was not fully recovered in the old days due to the technique limitation. In some gold tailings, the gold content is as high as 2~8g/t, if using the JXSC gold ore ball mill to retreat and recover gold, its potential economic benefits are huge.
