China Rod Mill for Mineral Processing - Efficient Suppliers and Factory Solutions
Performance characteristics
The rod mill produced by Minjie Company is different from conventional mining ball mills in that it uses a V-belt drive, and the cylinder belt position is processed into a V-belt groove through a large CNC floor lathe, which can save energy and reduce costs.
Comparison of Belt Drive and Traditional Ring Gear Drive for Minjie Mechanical Mining Ball Mills
| Agile machinery | Transmission form | Comparative analysis | |
|---|---|---|---|
| Transmission structure | Belt drive | Ring gear transmission | Ring gear transmission has high noise and maintenance costs |
| Lubrication form | Belt does not require lubrication | Dip-feed Lubrication | The gear ring guard is prone to oil leakage and there is a lot of oil contamination on site |

Frequently Asked Questions (FAQ)
1. How does Minjie's rod mill differ from traditional mining ball mills?
Minjie's rod mill features a V-belt drive instead of a conventional ring gear drive. The cylinder belt position is precision-processed into a V-belt groove using a large CNC floor lathe, which enhances energy efficiency and lowers operational costs.
2. What are the main benefits of the V-belt drive compared to a ring gear transmission?
The V-belt drive eliminates the high noise levels and heavy maintenance costs associated with traditional ring gear transmissions. Additionally, it does not require lubrication, preventing site oil contamination.
3. Does the belt drive system require regular lubrication?
No, the belt system does not require any lubrication. This is a significant advantage over traditional dip-feed lubrication systems which are prone to oil leakage.
4. Can the technical specifications of the ball mills be customized?
Yes, corresponding models can be customized and designed to meet specific customer requirements. High-power motors can also be configured using medium voltage motors.
5. What is the maximum production capacity available for these models?
The production capacity varies by model, ranging from 40-150 t/h for the QCZ2736Z model up to 80-280 t/h for the high-capacity QCZ3254Z model.
