About
Sixty years of grain machinery, in one factory in Shandong
The company's predecessor was the Shandong Flour Machinery Factory. That lineage is why our frames are heavier than they need to be, and why every wear part is designed to be replaced by a local workshop.
- 60+ years manufacturing
- 10–500 t/d capacity range
- 100+ patents
- Turnkey commissioning
The company
A national high-tech enterprise that still builds its own frames
Shandong Sishui Haiyun Grain Machine Co., Ltd. is located in the Sishui Economic Development Zone in Jining, Shandong. The company was incorporated in 2010, converted from the former Shandong Flour Machinery Factory, and carries more than sixty years of accumulated grain machinery manufacturing experience.
Registered capital is CNY 12 million. The site covers more than 60,000 m², of which 20,000 m² is covered processing workshop. Raw material enters as laser-cut plate; roll housings are machined on CNC centres. Production is organised across dedicated milling machine workshops, an integrated assembly hall, a material cutting shop and a finished goods area.
The product range has formed six systems and more than thirty products, capable of delivering turnkey flour plants from 10 to 500 tonnes of wheat per 24 hours. In recent years the company has added buckwheat, rice hulling and milling, corn flour and grits, oat and oat flake, chilli powder and stone grinding equipment.
More than one hundred patents are held. The company is recognised as a national high-tech enterprise, holds an import and export products licence, and has passed ISO 9001:2015 international quality system certification. Equipment is exported to Eastern Europe, the CIS, Mongolia, South Korea, Japan, South America, Africa and Southeast Asia.
Holder of an import and export products licence, and certified to the ISO 9001:2015 international quality management system.

The workshops
What happens inside
Dedicated bays, each with its own quality gate. Material does not move to the next stage until the previous one has been inspected. Photographs below are from the 2026 catalogue, with the brochure's own captions.
Roller mill workshop Ⅰ & Ⅱ
Two dedicated bays for roll stand assembly. Housings are machined on CNC centres, then assembled and aligned in these bays — roll parallelism is verified to 0.05 mm before a stand leaves the floor.
Integrated assembly Ⅰ & Ⅱ
Plansifters, purifiers and cleaning equipment are assembled and test-run here, then complete plants are pre-assembled for factory acceptance testing before crating.
Production workshop
General fabrication and machining. Plate enters as laser-cut blank; the workshop turns it into frames, spouting and structural steel for the plant.
Qualifications
Certificates, licences and honours
National high-tech enterprise status, ISO 9001:2015 quality management certification, import and export products licence, and provincial manufacturing awards — the paperwork an industrial buyer asks for during vendor qualification.
Certificate images are reproduced at catalogue resolution. Full-size scans and validity dates are available on request for vendor qualification files.
Export
Seventy years of manufacturing experience, shipped to forty countries
Equipment has been exported to Eastern Europe, the CIS, Mongolia, South Korea, Japan, South America, Africa and Southeast Asia. Export documentation, CE marking on selected models, and English, Russian and Spanish technical manuals are standard on export orders.
