About Dongyue Machinery Group: AAC Block Plant Manufacturer Since 1994

NEEQ-listed (stock code 838849) with 85 patents and more than 1,000 turnkey AAC block and panel plants delivered in 50+ countries. We engineer, manufacture, install and commission the complete line — then keep it running through five overseas offices.

Company Profile

Dongyue Machinery Group Co., Ltd. has designed and built autoclaved aerated concrete (AAC) plants since 1994. From a single equipment workshop in Yinan County, Shandong, the company has grown into a NEEQ-listed group (stock code 838849) operating four subsidiaries from a 213,600 m² manufacturing base.

Those subsidiaries — Linyi Dongyue Building Material Equipment, Linyi Dongyue Pressure Vessel Equipment Manufacturing, Linyi Dongyue Import & Export, and Shandong Huitian New Material Technology — cover the whole chain: AAC plant engineering, block and brick making machines, stone-coated metal roofing tiles, and pressure vessel manufacturing.

With 85 patents and a role as lead drafter of several national and industry technical standards, we keep every line competitive on cycle time, steam consumption and block accuracy. More than 1,000 projects in over 50 countries are supported by overseas offices in five countries.

To us a plant is not finished at handover — it is finished when your line runs at rated capacity, every shift, with local support behind it.

Four subsidiaries, one accountable supplier

Plant engineering, pressure equipment, export logistics and material R&D all sit inside the same group — so responsibility for your line is never handed to a third party.

From inquiry to first block in five steps

A turnkey AAC plant typically reaches first production 6–10 months after contract signing. Here is what happens at each stage.

Needs analysis

You share target capacity (m³/year), raw material, site size and budget. An engineer — not a salesperson — replies within 24 hours.

Material test & process design

We test your fly ash or sand and lime, then lock the mix design and process route before any quotation is issued.

Layout, BOM & quotation

A capacity-matched line configuration, whole-plant layout, itemised equipment list and delivery schedule.

Manufacturing & pre-assembly

Equipment is built in our own plants and trial-assembled before shipment, so site work is assembly — not rework.

Commissioning & training

Installation supervision, commissioning to rated capacity, and operator training before handover.

Tell us your capacity target — get a plant layout and budget in 24 hours

Send your raw-material type, target output in m³/year and site size. Our engineers reply with a capacity-matched line configuration, a whole-plant layout and an itemised budget. No obligation, no sales pressure.
