Three types of grinding mills for gold ore

26/07/13 Tags: business

Gold ore grinding unit refers to grinding mills used in the grinding process of gold ore. Usually, grinding is finished after crushing, and makes a preparation for gold extraction. Since the foundation day of our company, Shanghai Hongxing has made a great contribution to global gold mining industry. We can design and produce every machine needed in the gold processing line. Here we focus on main types of gold ore grinding unit in China, also called gold ore grinding facility.

In China, gold ore grinding units have varied types, such as ball mill, rod mill, and vertical mill. The following are details of them.

Ball Mill

In China, ball mill is widely used as the gold ore grinding unit. Typically, ball mill has two warehouses. When it works, gold ore enters spirally and evenly the first warehouse of the milling machine along the input material hollow axis by input material device. In this warehouse, there is a ladder scale board, and different specifications of steel balls are installed on the scale board, when the barrel body rotates and then produces centrifugal force, at this time, the steel ball is carried to a certain height and falls to make the material grinding and striking. As for Hong’s ball mill, it features simple operation, low energy consumption and high capacity.

Rod Mill

Besides the ball mill, rod mill performs as another common type of gold ore grinding unit in China. The motor of rod mill drives through the reducer and peripheral big gear, or the low-speed synchronous motor directly drives the rod mill through big gear around rod milling machine to drive the cylinder body rotation. The cylinder body is filled with appropriate grinding medium – steel bar. In the function of centrifugal force and friction force, the grinding medium is promoted to a certain height, and then is thrown or relief in the falling state.

Vertical Mill

Vertical mill is an advanced gold ore grinding unit. Compared with other types of gold ore grinding unit, it integrates the function of drying, milling, grading and transporting into one set. It is the high standard mill which can meet the high capacity of powder producing request. From crushing of raw material to grinding and packing is an independent production system. Compared with other milling plants, its passing ratio achieves 99%, this is what other mill cannot reach.

Practice has proved that the gold grinding unit designed by Hongxing can bring rich returns to your investment. If you have a great interest in our gold grinding units, please contact us, and we will make a big difference to your gold mining business!
