Product Description
Our high hardness grinding steel rods have undergone various heat treatments to improve the wear and impact resistance. We select the right alloy steel to fit your rod mill and reduce your grinding costs.
a.The dimensional tolerance would abided by the requirements of the order. After the implementation of blanking, the two ends of the raw material are polished into the R arc via the polishing machine.
b. The surface of the product for the rod mill cannot have the crack, overburning and fissure visible to the naked eyes.
c. The nonstraightness:<0.2%.
Diameter tolerance: +0mm to -1.5mm.
Length tolerance:+0mm-25mm.
Breakage Rate:<3%.

3. Application And Packing
The steel grinding rod is the optimum choice for the enterprises using the rod mill and the coal mill, such as cement plant, electric power plant, mine, quartz sand plant, silica sand plant, sand aerated industry, coal chemical industry, gas concrete plant, etc.
We pack our products by barrel or bundled
4.Production process
We have the strict steel materials inspection rules for incoming materials.
The production process is strictly controled for each process.
5. Production lines for Grinding steel rods
The production lines for grinding steel rods are made and designed by our expertise. And it is the first one production line for grinding rods in China in 2009.
For the large quantity required from customers, we can supply the production lines of grinding rods and expand our production to meet the customers' requirements.
5. Certification and patent
Our company has obtained ISO 9001 International Quality System Authentication, ISO14001 Environmental System Management Authentication and ISO18001 occupational health and safety certification, safety standardization identification, clean production enterprise certification.
6.Cooperative Partner
70% of our products are exported ,and we are keeping close cooperation with many large companies.
