Vietnam 200 TPD Ball Mill – Shipped and Delivering Results

Henan Hongke Heavy Machinery Co., Ltd. recently completed shipment of a 200-ton-per-day ball mill line to a mining customer in Vietnam. Here's the real story—what they struggled with, what we built, and what actually happened after startup.

The Problem: Their Old Mill Was Killing Their Bottom Line

Our customer runs a medium-scale mineral processing plant in Vietnam. Before they came to us, their existing ball mill was a constant headache:

• Throughput was stuck around 145 TPD – well below their 200 TPD target

• Energy bills were through the roof – over 35 kWh per ton

• Particle size was all over the place – bad for their flotation recovery

• Breakdowns were routine – bearings failed, liners wore out fast, and they lost hours every day to unplanned stops

• Dust was everywhere – operators hated it, and regulators were starting to notice

• Maintenance ate up too much time and labor – daily manual fixes that shouldn't have been necessary

The old mill wasn't designed for their ore. It was a generic machine, and it showed.

What They Asked For

When they put out their requirements, they were very specific:

• 200 TPD – no excuses, no "almost"

• Under 28 kWh per ton – energy cost was a major driver

• P80 under 74 microns – tight particle distribution for better flotation

• 95% uptime – they couldn't afford daily breakdowns

• Dust collection that actually works – to meet local environmental rules

• Less hands-on maintenance – they wanted to free up their crew

"We don't want promises. We want a mill that runs, hits the numbers, and doesn't need babysitting." — Their production manager, straight up.

What We Built for Them

We don't sell standard machines off a shelf. Every mill we make is matched to the material, the site, and the target.

For this job, we delivered a Φ1.83×3.6m grid-type ball mill with:

• High-manganese steel wave liners – custom profile to lift the charge just right

• A carefully calculated ball charge – size mix optimized for their ore hardness

• Heavy-duty edge drive – reliable, easier to maintain than center drive

• Roller bearings instead of Babbitt bearings – less friction, less power draw

• Labyrinth seals – keeps dust in, keeps contamination out

• A pulse-jet bag filter – emissions under 20 mg/m³

We also supplied the full system around it: feeder, classifier, slurry pump, control panel, and all ducting. It was all pre-assembled and test-run at our factory before shipment.

Why This Mill Is Different

A few things set this machine apart from what they had before:

• The shell runs cooler and lasts longer – proper material selection and welding processes

• The bearing design cuts energy loss – rolling bearings save roughly 15–20% in friction vs. old-school plain bearings

• The liner shape keeps grinding efficient – no dead zones, no wasted impacts

• The control panel gives real-time feedback – amp load, bearing temps, lube status – all at a glance

• The sealing system keeps dust contained – cleaner plant, happier operators, safer compliance

We didn't just ship a drum with a motor. We shipped a grinding system that's built for their feed size (up to 25mm), their hardness, and their 24/7 schedule.

The Numbers That Matter

Here's what changed after they switched to our mill:

Bottom line: They're saving around $185,000 per year on energy, maintenance, and downtime combined.

Just the energy savings alone are over $130,000 a year – and that's before counting the extra tonnage they're now selling.

What the Customer Says

Six months in, their production director told us:

"This mill delivered everything we asked for – and more. The energy savings alone paid for a big chunk of the investment in year one. We're finally hitting our contract volumes consistently. Henan Hongke didn't just sell us a machine – they gave us a solution that fits our ore, our people, and our business."

Support That Doesn't Stop at Delivery

We don't disappear after the container leaves the port. For this project, we provided:

• On-site installation supervision

• Operator training (in Vietnamese, through our local agent)

• A 12-month warranty on major components

• Spare parts stocked and ready to ship

• Remote support via video call – quick, practical, no runaround

Quick Takeaway

If your grinding circuit is underperforming – low tonnage, high power draw, inconsistent size, constant repairs – you don't need a "machine." You need a solution that's engineered for your specific ore and production goals.

That's exactly what we delivered to Vietnam. And we can do the same for you.
