Φ2.6m Rod Mill Liner

One of our customers had asked us to manufacture Ni-hard mill liner for his Φ2.6m Rod Mill. Rod mill uses steel rods as the grinding media in tumbling mills is an efficient means to feed ball mills a product finer than could be made in a crusher but coarser than could be made in a ball mill. The principal use for rod mills, which were invented to make ball mill feed in a wet-grinding rod mill-ball mill circuit.

Φ2.6m Rod Mill Liner Production Process

Normally, we use the sand casting method to cast those mill liners, the production process steps as the following:

  1. Our sale manager checks with the customer about the orders;
  2. Our engineer team to do process design;
  3. Purchase the raw material, and checking or making patterns;
  4. Inspection of the raw material;
  5. Melting by middle-frequency induction furnace;
  6. Lable analysis by a spectrometer before casting, and molding;
  7. Deoxygenating, slag-removal, and tapping;
  8. Pouring;
  9. Opening and fettling;
  10. Surface and dimensional checking, if not pass, the parts need scrap casting back to the furnace;
  11. Heat treatment;
  12. Machining, checking, and printing

Quality Control

All the wear parts must pass our strict quality control system in the production process. After the finish the goods, we will also give customers quality reports.
