How to Eliminate the Internal Stress of HPGR Hard Alloy Pins?

How to Eliminate the Internal Stress of Hpgr Hard Alloy Pins?

In the sintering and molding process of the Carbide Button, the cooling speed of a vacuum furnace slowed down after the alloy of the product is finished.

HPGR Pin Stud is subject to deep cold treatment in liquid nitrogen for 6 hours. The hard alloy Carbide Pin is restore to the normal temperature in a natural state, the temperature in the furnace raised to 400 degree C, and the hard alloy studs are subjected to temper heat treatment to improve the crystal image structure of the metal cobalt.

Ball mill and polishing for 3 hour to eliminate the residual stress of the Hard Alloy Stud.

The process flow can improve the strength of the hard alloy stud and prolong the service life.

High Pressure Grinding Rolls has such features of high grinding efficiency, low energy consumption, big crushing ratio, could instead exist rough crushing fine crushing and milling works in the process of mine crushing and grinding. High Pressure Grinding Rolls could crush 30-60mm ore blocks into less than 3mm, in order to achieve lots of tailing discarding before mine grinding, provide a great improve of ore grinding and separation ability of the system.
