Why mills buy from us

Sixty years of one thing: grain machinery.

The company’s predecessor was the Shandong Flour Machinery Factory. That means our engineering lineage runs back to the era when a flour mill was assembled from castings made on site. What survived from that period is a bias toward over-building: heavier frames, replaceable wear parts, and machines that a local workshop can repair.

What changed is precision. Raw material now arrives as laser-cut plate; roll housings are machined on CNC centres. The result is a plant that costs what a mid-market plant costs and holds tolerance like a premium one.

About the factory →

Flow sheet included

Every quotation includes a cleaning and milling flow diagram — not just a price list.

Guaranteed tonnage

Contracted output and extraction, verified over a 72-hour performance test.

Spares on the shelf

Roll packs, screens, beaters and bearings kept in stock for 10 years post-delivery.

Operator training

Two to six weeks on site, plus remote support for the first harvest season.

Knowledge centre

The engineering we would want a supplier to send us

In-depth handbooks on plant sizing, wheat procurement, cleaning, flow sheets, stone milling, quality control and plant economics. No gatekeeping.

All handbooks →

Our engineering handbooks and reference project records are written for mill engineers and stay in English. The commercial pages — plant range, equipment, about and contact — are available in your language. →
