China Suppliers Minjie Rod Mill for Mineral Processing - High Efficiency Factory Equipment
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)
What makes Minjie's rod mill different from conventional mining ball mills?
Minjie's rod mill uses a V-belt drive instead of the traditional ring gear transmission. The cylinder belt position is precisely processed into a V-belt groove using a large CNC floor lathe, which significantly saves energy and reduces operational costs.
What are the main advantages of a belt drive over a traditional ring gear drive?
Traditional ring gear drives generate high noise levels, require complex dip-feed lubrication, and are prone to oil leakage from the gear ring guard. Minjie's belt drive system operates quietly, does not require lubrication, eliminates site oil contamination, and lowers maintenance costs.
Does the belt drive system on the mining mill require lubrication?
No, the belt drive system does not require any lubrication, which helps keep the working site clean and free of oil contamination.
Can Minjie customize the rod mill specifications and motor power?
Yes. While we provide standard technical models, corresponding models can be customized and designed according to specific customer requirements. Additionally, high-power motors can be designed utilizing medium voltage motors.
What is the production capacity and ore discharge particle size of these mills?
Depending on the model, the production capacity ranges from 40 t/h to 280 t/h, and the ore discharge particle size ranges between 0.15 mm and 3 mm.
