This is apple from shandong iraeta, a joint venture with spain. Kindly inform you we are a professional grinding ball manufacturer.
Our company specializes in producing all kinds of grinding steel balls for minings and our products have been exported to all over the world. And we have enjoyed a high reputation both in china and other countries.
1 > High Hardness: Surface hardness: HRC57-67 HRC, volume hardness HRC56-64.
2 > High Impact Toughness: The impact toughness of our grinding balls is more than 12 J / cm2.
3 > Low Broken Rate: the actual broken rate is not higher than 1%.
4 > Good wear-resistant and lower wear rate.
Company Information
Shandong Iraeta is a Sino-Spanish joint venture and its shareholders include Gestamp group which is the biggest steel deep processing enterprise of Spain. Shandong Iraeta has been one of the leading forging enterprises of China since it started business in 1975, Until now, it owns more than 20 international and industrial certifications and has assisted the draft and approval of two national industrial standards as well as one Torch Program project.
With over 20 of the global top 500 enterprises purchasing various kinds of forgings from us for different uses, we have customers in the fields of mining, shipbuilding, Petrochemical industry, wind power mechanical manufacturing, ect.
Raw material
Iraeta had strict quality control procedures for raw materials which were only purchased from audited steel mills, so the performances of grinding ball could be assured from source. Moreover, Iraeta set up the academician workstation cooperated with Shenyang Metal Institution of CAS, which enabled us to supply customized raw materials since the grinding media requirements varied by different region mines.
Technical strength
With our special heat treatment, the grinding rod has low wear rate, high hardness (about 45-55 HRC) and good toughness.
After removing the internal stress by quenching and tempering, our grinding rod will not break, bent or thin for two sides. The good resistance will help customers decrease the total costs. With the powerful technological strength, we are capable to meet customersâ?? requirements for any specification, which increases flexibility largely and reduces unnecessary waste.

Casting iron balls include high chromium balls, medium chromium balls and low chromium balls.
Quality index of high chromium casting ball:
The chromium content of the high chromium ball is 10.0% or more. The carbon content is between 1.80% and 3.20%. According to national standards, the hardness of the high chromium ball must be no less than 58hrc, and the impact value should be greater than or equal to 3.0j/cm2. To achieve this hardness, the high chromium ball must be quenched and tempered at high temperature. At present, there are two methods for quenching high chromium balls in China, including oil quenching and wind quenching. If the test hardness of the high chromium ball is lower than 54HRC, it means that it has not been quenched.
Quality index of medium chromium casting ball
The specified chromium content of the medium chromium ball ranges from 3.0% to 7.0%, and the carbon content is between 1.80% and 3.20%. Its impact value should not be less than 2.0j/cm2. According to national standards, the hardness of the chrome ball should be greater than or equal to 47hrc. In order to ensure quality, medium chromium balls should be tempered at high temperature to eliminate casting stress.
If the surface of the iron ball is black and red, it proves that the iron ball has been tempered at high temperature. If the surface of the iron ball still has the metal color, we can judge that the iron ball has not undergone high temperature tempering treatment.
Quality index of low chromium casting ball
Generally speaking, the chromium content of the low chromium ball is 0.5% to 2.5%, and the carbon content is from 1.80% to 3.20%. Therefore, according to the national standard, the hardness of the low chromium ball should be no less than 45hrc, and the impact value should be no less than 1.5j/cm2. Low chromium balls also need high temperature tempering treatment to ensure quality. This treatment can eliminate casting stress. If the surface of the iron ball is dark red, it indicates that it has undergone high temperature tempering treatment. If the surface is still metallic color, it means that the iron ball has not been tempered at high temperature.
Casting iron balls are usually used in various large-scale mines, cement plants, chemical plants, power plants, quartz sand plants, silica sand plants, etc.
