Baichy large ball mill 2400x4500 for gold ore delivers to Indonesia

Gold ore ball mill is a kind of equipment that grinds gold ore into powder. It is one of the indispensable equipment for pre-selection operation in the ore dressing plant. Only after grinding, the gold ore reaches the required particle size, it can enter the selection stage and obtain high-grade gold concentrate.

Baichy ball mill QMJ2400X4500 is a large grid-type ball mill used for the first stage of grinding in gold mines. Indonesian customers visited several ball mill factories in China, fully understood the materials, related supporting configurations and services of our Baichy ball mill, and finally chose to cooperate with us.

Characteristics of Baichy ball mill 2400x4500 features

1. The ball mill is mainly composed of a feeding device, a rotating cylinder, a grinding media , a transmission device and a discharge device.
2. The transmission device consists of a small gear unit, a main motor, a main reducer, a slow transmission device (auxiliary motor + reducer), a coupling, a clutch operating mechanism, a base and a coupling shield.
3. There is a discharge grid at the ball mill discharge end, and the grid plate has a discharge hole. The ore is forced to be discharged by the grid plate. The ore slurry surface in the cylinder is low, which reduces the over-grinding of the ore and prevents the discharge of the steel ball. Rolling bearings are used at both ends of the cylinder. The grid type ball mill is suitable for processing gold ore with a coarse particle size due to its special structural design. In gold mines, it is generally used for coarse grinding in one stage of grinding.
4. The manganese steel liner of the ball mill 2400x4500 is ZGMn13-4, and the steel ball is a high-chromium cast steel balls.
5. Large ball mills use slip ring motors, which have high overload capacity, smooth acceleration under heavy load, and no abnormal heating during startup. Compared with squirrel cage motors, slip ring motors can achieve maximum startup by inserting external resistors in each phase of the rotor circuit and cutting off the resistors during startup.
6. Adopt liquid resistance starter cabinet(LRS), high/low voltage switch cabinet and static phase advancer.

The ball mill has now been successfully delivered to Indonesia on time. The ball mill will be shipped to the customer site by sea, and we will send engineers to the site to guide the installation.

People Also Frequently Asked For - FAQ

1. What is the principle of ball mill?

It works on the principle of impact and attrition. Impact occurs when the balls are lifted by the rotating mill and then drop onto the material to be ground. The force of the impact breaks the material into smaller pieces. Attrition occurs when the balls rub against each other and against the material to be ground.

2.How do you calculate ball mill capacity?

The volume of a ball mill is typically calculated by multiplying the total volume of the mill, including the void spaces between the balls and the material being milled, by the fraction of the mill volume filled by the balls. This fraction is typically between 30% and 50%.

3.Why different size balls are used in ball mill?

The ball size is one of the critical factors for determining the mill performance of ball mills. It is well known that larger balls are needed for the effective breakage of large-size particles, whereas smaller balls are more effective for the breakage of fine particles.
