Frequently Asked Questions (FAQ)
How does Minjie's rod mill differ from traditional mining ball mills?
Unlike conventional mining ball mills that use a ring gear drive, Minjie's rod mill features a V-belt drive. The cylinder belt position is precisely machined into a V-belt groove using a large CNC floor lathe, which effectively saves energy and reduces overall costs.
What are the main benefits of a V-belt drive over traditional ring gear transmission?
Traditional ring gear transmission is associated with high noise and high maintenance costs. In contrast, the V-belt drive operates with much lower noise, requires no lubrication (eliminating oil leakage and contamination on site), and reduces maintenance expenses.
Can the technical parameters of the ball mills be customized?
Yes, while standard models are readily available, customized models can be fully designed according to specific customer requirements. This includes the integration of high-power motors using medium voltage configurations.
What is the production capacity and discharge particle size of these mills?
Based on our standard models (from QCZ2736Z to QCZ3254Z), the production capacity ranges from 40 to 280 tons per hour (t/h), and the standard ore discharge particle size ranges from 0.15 mm to 3 mm.
Why does the V-belt drive improve site cleanliness?
The V-belt drive requires no lubrication. In comparison, traditional ring gear systems rely on dip-feed lubrication, where the gear ring guard is prone to oil leakage, leading to significant oil contamination on the work site.
