From the banks of the Yangtze River to the Gulf of Guinea, Liyuanheng is forging a new era of mining together with African partners

Date: August 1, 2025

Client: Technical delegation from a large bauxite mining company in Cameroon

Purpose: To evaluate the performance of the LYH1750 Raymond mill in grinding high-viscosity bauxite ore in Africa and its localization support capability

1. At 9:30 AM, the delegation arrived at Liyuanheng Raymond Mill Nantong Intelligent Factory. General Manager Mr. Ding personally welcomed them and warmly shook hands with the Procurement Director of the Cameroonian mining company. The Cameroonian client expressed, "Our project at Kribi Port urgently needs to solve the clay clogging problem. We look forward to Liyuanheng’s solution!"

Technical Engineer Wang presented via tablet:

• Successful African case: Raymond mill at Ghana manganese mine ran continuously for 12 months without major repairs;

• Cameroon adaptation design: Customized duct heating anti-clogging system tailored for the high moisture and high viscosity characteristics of bauxite.

2. Company Presentation: China-made commitment to Africa

3. Technical Seminar
   The meeting room’s large screen played the French version of the promotional video. General Manager Mr. Zhou opened with a speech: "Liyuanheng has served clients in 17 African countries. We deeply understand that stability and power fluctuations are core pain points." Then the Technical Director explained:

• Power adaptation: Wide voltage design (380V±20%), optional diesel generator module;

• Anti-clogging revolution: Patented vortex air sorting technology, increasing clay throughput rate by 50%;

• Localization commitment: Spare parts center established in Douala, Cameroon, with 90% of fault parts delivered within 24 hours.

2. Key Q&A
   Client sharply asked, "How do you handle the muddy problem of bauxite containing 35% moisture during the rainy season?"
   Technical response:

3. Added microwave moisture evaporator at feed inlet

4. Embedded ceramic heating plates on the mill chamber walls, with intelligent temperature control

5. On-site playback of Cameroon ore test video: 35% moisture material still maintains 98% throughput rate

3. Factory Tour: Manufacturing DNA customized for Africa

4. Wear-resistant parts production line

• High-chrome alloy grinding roller casting: Showcased Cr20Mo bimetal composite rollers specially designed for high quartz African ores (tested life: twice that of ordinary rollers)

• On-site test: Clients conducted wear comparison tests with their own Cameroonian ore samples, showing Liyuanheng rollers had 41% less wear

2. Final assembly workshop

• Africa special models: Yellow paint (for sand and dust environment), rodent-proof cables, anti-salt spray coating

• Power test: Simulated African grid fluctuation (voltage drop to 300V), equipment operated smoothly

3. Intelligent operation & maintenance center

• AR glasses demonstration: French interface guided roller replacement, client personally operated and praised, "Smarter than the equipment we purchased in France!"

4. Business Negotiations: Solving operational difficulties in Africa

Pain point attacks

Signing results
Both parties signed:

1. Purchase agreement for 2 sets of LYH1750 Raymond mills (including rainy season special anti-clogging package)

2. "Africa Operation & Maintenance Alliance" plan: Liyuanheng trains Cameroonian technicians to jointly serve the China-Africa market

5. Cultural Resonance: From the Yangtze to the Sanaga River

The banquet was held by Nantong’s Zilang Lake, featuring:

• Taste diplomacy: Steamed clam egg custard paired with Cameroonian spicy bean sauce; chef taught the Chinese “Fu Fu” (cassava dough) live

• Technical celebration: When demonstrating the mobile app’s remote start/stop function, the delegation stood and applauded

• Meaningful gifts: Mr. Ding presented a Shen embroidery “Wolf Mountain Scenic View,” the client returned a replica of a Cameroonian chief’s staff, saying, "May it become Liyuanheng’s staff of authority in West Africa!"

6. Africa Strategic Upgrade Plan

Based on this visit, Liyuanheng announced:

1. Localization in Cameroon: Assembly plant to be established in Douala by 2026 (reducing tariff costs by 40%)

2. Climate laboratory: Equipment testing simulating equatorial rainforest environment (40°C temperature + 95% humidity)
