Large ball mills are widely used in many large-scale ore dressing plants. Compared to multiple small and medium-sized ball mills working simultaneously, choosing a large ball mill with suitable models and parameters can undoubtedly save a lot in investment costs. Now, let's take a look at Xin Hai's large ball mills.
What kind of ball mill can be considered a large ball mill? According to the classification based on the cylinder diameter, we define a ball mill with a cylinder diameter greater than 3 meters as a large ball mill. Xin Hai's production of large ball mills mainly includes two series: the 3.2 series and the 3.6 series, representing models with cylinder diameters of 3.2 meters and 3.6 meters, respectively.
Why doesn't Xin Hai produce ball mills with a diameter of more than 4 meters? This is because, if the cylinder diameter of the ball mill is ≥4 meters, there will be some drawbacks, such as reduced operational flexibility, poor motor starting performance, excessively high internal temperature, high power consumption, low rotation speed, low working efficiency, and transportation difficulties, among a series of other problems.
These are all issues summarized by Xin Hai through hundreds of project experiences over more than 20 years. From the establishment of Xin Hai to the present, our ball mill products are constantly updated and iterated. We introduce advanced production processes from both domestic and international sources and use cost-effective materials and components to ensure a high-quality experience for our customers. Ultimately, Xin Hai defines the models of large ball mills as those with cylinder diameters ranging from 3 to 3.6 meters.
For the 3.2 series, the large ball mill includes three models: MQG 3231, MQG 3236, and MQG 3245. For the 3.6 series, there are four models: MQG 3639, MQG 3645, MQG 3650, and MQG 3660. The listed models here are grid-type ball mills, and Xin Hai also produces large overflow-type ball mills with equivalent specifications.
Parameters for large ball mills are also a significant concern for many friends. Parameters describe a set of data about the equipment from various aspects, including volume, power, ball loading, weight, processing capacity, and a series of other data, providing customers with a more intuitive and detailed understanding of each piece of equipment.
Xin Hai's production process for large ball mills is advanced, and the parameter design is reasonable. Summarizing, it has the following advantages:
1.Large discharge opening design: Large discharge volume, strong production capacity.
2.Selection of domestic advanced large double-row self-aligning roller bearings: Even for large ball mills, starting is very easy, reducing friction and saving energy.
3.Motor power is matched with the ball mill model: The power is not too small to drive the cylinder to rotate at a constant speed, and not too large to waste resources.
4.Reasonable upper limit of ball loading: The upper limit of ball loading is set at around 40% of the cylinder volume, ensuring the grinding effect of large ball mills.
The table below shows the detailed parameters of Xin Hai's large ball mills:
| Model | Motor Model | Motor Power (kW) | Length (mm) | Width (mm) | Height (mm) | Effective Volume (m3) | Max. Ball Load (t) | Weight (kg) |
|---|---|---|---|---|---|---|---|---|
| MQG 3231 | TDMK630-36 | 630 | 12750 | 6750 | 5152.5 | 22.5 | 45 | 115103 |
| MQG 3236 | TDMK630-36 | 630 | 14300 | 6760 | 5200 | 24.8 | 58 | 119012 |
| MQG 3245 | TDMK800-36 | 800 | 13896 | 7200 | 5152.5 | 32.8 | 65 | 137589 |
| MQG 3639 | TDMK1000-36/3600 | 1000 | 15000 | 7200 | 6300 | 36.2 | 75 | 145000 |
| MQG 3645 | TDMK1250-40 | 1250 | 15200 | 7750 | 6300 | 41.8 | 90 | 159700 |
| MQG 3650 | TDMK1400-40 | 1400 | 17600 | 7750 | 6300 | 46.4 | 96 | 158000 |
| MQG 3660 | TDMK1600-40 | 1600 | 17000 | 8800 | 6500 | 55.7 | 120 | 189000 |
Through the above parameters, I believe you have gained a certain understanding of large ball mills. Do you find the model you need? If not, it's okay. Xin Hai can provide customized services for customers. If you provide the design drawings, we can manufacture according to your requirements. Even if you don't have design drawings, our professional mechanical equipment engineers can provide design services based on the data you provide. After finalizing the design drawings, we can produce large ball mill equipment that meets your needs.
In summary, we introduced the specifications and specific parameters of large ball mills. With the continuous expansion of the ore product market, the demand for large ball mills is gradually increasing. In the future, Xin Hai will continuously develop new technologies and processes, optimize product performance, make our equipment more powerful in production capacity, and achieve higher grinding efficiency, becoming more competitive in the market.
