• HPGR High Pressure Grinding Rolls | Weir

    Used in mining appliions for the last 30 years, high pressure grinding rolls (HPGR) reduce particles by compressing and crushing the feed between two counter rotating, parallel rollers with a small gap between them. This forces the rocks against each other and compresses the feed's density to 80% of its solid volume, exceeding its ...

  • What are Hertz contact stresses and how do they affect ...

     · Preloading the rolling elements gives them a larger — and finite — Hertz contact area, which increases stiffness. But the increased contact results in high heat generation. This is why a preload amount of just 8 percent is considered high preload for linear bearings, with preload greater than 10 to 15 percent being extremely rare.

  • Hydraulic And Mechanical Presses

    Hydraulic presses are a powerful class of machine tools, they derive the energy they deliver through hydraulic pressure. Fluid pressure, in a particular chamber, can be increased or decreased by the use of pumps, and valves. Sometimes devices and systems may be used to increase the capacity of the pumps in more powerful presses.
