Energy consumption of 1530 grid ball mill: 80kW

Processing capacity of 1530 grid ball mill: 2.8~9t/h

Main parameters of 1530 grid ball mill: motor model-JR117-8, effective volume-5m³, ball loading-10t, weight-21425kg

1530 grid ball mill is widely used in many small and medium-sized metal and non-metallic ore dressing plants. The grid ball mill runs smoothly, the discharge particle size is uniform, and the overall frame design is adopted, which is convenient for civil construction and equipment installation. In addition, the 1530 grid ball mill has the advantages of energy saving, large processing capacity and reasonable parameters. Let's analyze them one by one.

Compared with ordinary grid-type ball mills of the same model, the 1530 energy-saving grid-type ball mill can save about 30% of energy, mainly because of the following changes:

1. Selection of bearings
We know that the grid-type ball mill is large in size and heavy in weight, and consumes a lot of power when starting. If the power consumption of the grid-type ball mill can be reduced when starting, energy saving can be achieved. The energy-saving grid-type ball mill produced by Yingkuang adopts large double-row spherical roller bearings. Compared with traditional sliding bearings, this bearing greatly reduces friction, making the grid-type ball mill easier to start and saving 20%~30% of energy.

2. The shape of the liner is particular
The main function of the liner is to protect the cylinder of the grid-type ball mill to prevent the inner wall of the cylinder from being continuously hit by steel balls and materials, causing the cylinder to deform or even leak.

The energy-saving 1530 grid ball mill of Yingkuang makes full use of the role of the liner. The corrugated liner not only protects the inner wall of the cylinder, but also fits the spherical surface of the steel ball, driving the steel ball to rise upward. When it is lifted to the highest point of the cylinder, the steel ball falls rapidly downward under the action of gravity.

3. Increase the diameter of the discharge port

Increasing the diameter of the discharge port of the 1530 grid ball mill can prevent large pieces of ore from blocking the discharge port. Not only can large pieces of ore not come out, but small pieces of ore inside are also blocked and difficult to discharge. The result is that the grid ball mill swells. The solution to the swell is to stop the machine, clear it, and then restart it, which will increase energy consumption and even delay the construction period.

4. Reliable oil mist lubrication device

The 1530 energy-saving grid ball mill is equipped with a reliable oil mist lubrication device to ensure reliable lubrication of large and small gears. The mutual bite between the gear teeth of the large and small gears accelerates the rotation of the grid ball mill barrel, which is also a key factor that makes the 1530 grid ball mill more energy-efficient than ordinary grid ball mills.

Compared with ordinary 1530 grid ball mills, the grid ball mills produced by Ying Mine have a larger processing capacity. The processing capacity of a single 1530 grid ball mill can reach 9t/h. Calculated based on 20 hours of continuous work per day, the daily processing capacity is about 180 tons.

PS: The processing capacity of the grid ball mill is affected by many factors, including but not limited to the feed and discharge particle size, the nature of the ore, the slurry concentration, whether the steel ball grading is reasonable, the temperature in the barrel, etc. Therefore, the above processing capacity is for reference only and needs to be considered comprehensively in combination with the actual situation of each project.

The above introduces the parameters and processing capacity of the 1530 grid ball mill, and deeply analyzes the key factors that make Yingkuang 1530 more energy-efficient. If you are looking for suitable equipment, please contact us!
