HMR forged grinding ball

  • 【Product Standard】Φ65-150mm
  • 【Product Density】7.85g/cm³
  • 【Range Of Application】All kinds of mines, building materials, electric power, chemical industry, etc
  • 【Product Presentation】It has the advantages of compact structure, high hardness, low crushing rate and low wear. When it is used in large ball mill and semi autogenous mill, the effect of saving energy and reducing consumption is remarkable.
  • 【Product Feature】1. Smooth surface, no defect, no deformation and no out of round. 2. Dense internal structure: the anti drop property and impact absorption energy (kn2 ≥ 12j) of the grinding ball are enhanced, so the wear resistance of the grinding ball is improved.

Note: FB forged ball: for Φ 65-80mm ball mill, the effective height difference is 8.5m; for Φ 90-150mm ball mill, the effective height difference is 10m.

Case analysis of HMR forging grinding ball

 

There are two series of grinding operation in a copper mine concentrator in Jiangxi Province. The specifications of the two semi autogenous mills are the same, and the operating conditions are completely the same. Series 1 adopts Φ 125mm forged grinding balls produced by HMR group, and series 2 adopts grinding balls from other manufacturers.

After 2 months of operation, the statistical analysis of the application effect of HMR forging grinding ball is as follows::

The average ball consumption of HMR forging ball is 490 g / T, and that of other manufacturers is 620 g / T. the unit ball consumption is reduced by 20.9%.

HMR forged grinding ball shows perfect combination of hardness and toughness, low wear rate, low crushing rate and no loss of roundness.
