Henan Hongke Heavy Machinery Co., Ltd. has delivered a Φ 3×16m ball mill for cement grinding to a customer in Russia. The mill is part of a cement production line and is used for clinker grinding. This article covers the full project: customer background, the original problem, equipment configuration, delivery timeline, commissioning results, and customer feedback.
1. Customer Background
Location: Russia (Central Federal District)
Industry: Cement / building materials
Russia has a well-established cement industry, with production concentrated in regions with access to limestone, clay, and fuel resources. Cement plants in the Central Federal District supply construction projects across European Russia, where demand for consistent-quality cement remains steady.
Our customer is a cement producer in this region. They operate a grinding station that processes clinker into finished cement. Their existing grinding equipment was aging and could not consistently meet product fineness targets or throughput requirements.
2. The Original Problem
Before approaching Henan Hongke Machinery, the customer faced several practical issues:
| Problem | Impact |
|---|---|
| Inconsistent cement fineness | Blaine surface area varied; downstream concrete quality affected |
| Low grinding capacity | Unable to meet market demand during peak season |
| High specific energy consumption | kWh per ton above competitive levels |
| Frequent liner and media replacement | Maintenance costs and downtime |
| Bearing temperature issues | Occasional unplanned stops |
| Dust leakage | Environmental and workplace concerns |
| Aging drive system | Reliability issues, difficult spare parts availability |
The customer needed a new mill—not a rebuilt or refurbished unit. Their goal: consistent fineness, higher throughput, lower energy cost, and reliable continuous operation.
3. Why the Customer Chose Henan Hongke Machinery
After evaluating several suppliers, the customer selected us for specific, practical reasons:
a) Grinding circuit discussion, not just mill dimensions
Cement grinding performance depends on the interaction of clinker grindability, feed size, media gradation, liner profile, mill speed, and separator efficiency. We discussed these parameters during technical exchange—not just diameter, length, and price.
b) Design matched to their clinker and target fineness
Clinker from different kilns behaves differently. We reviewed the customer's clinker characteristics and target Blaine surface area before finalizing the mill configuration, liner profile, and media gradation.
c) Complete grinding system supply
We supplied the mill shell, liners, grinding media, drive system (motor, reducer, girth gear), main bearings, lubrication system, and control panel—so the customer did not have to coordinate multiple vendors.
d) Cold-climate engineering
Russian winters impose additional requirements on lubrication, bearing clearances, and startup procedures. These were considered in the design.
e) Factory inspection and reference review
The customer reviewed our manufacturing facility and similar ball mill projects before signing.
f) Post-delivery support commitment
The customer wanted a supplier available for commissioning, media charging advice, and spare parts after handover.
