The 911MPEJAC23 is a Small Jaw Crusher of 2.25″ X 3″ manufactured to easily crush any rock from 2″ (50mm) down to a D50 of 700 micron (28 Mesh) which also correspond to a crushed discharge P80 size of 80% passing 1400 microns or 14 mesh.
The discharge opening (closed-side-setting) of this 55 mm X 75 mm “big-small crusher” you can adjusted with a wrench.
With a short throw at a quick 525 RPM (speed eccentric overhead), this small rock crusher can almost pulverize without dusting of your run-of-the-mill, chain beating, hammermill small prospectors often buy.
This portable and lightweight (35 lbs.), is perfect for low volume metallurgical sample preparation or any small home laboratory a gold prospector would have in his garage.
