Jeffery 30Ab Hammer Mill Reconditioned. With 40 hp motor. Perfect coal sample crusher, Complete with gaurds

The Jeffrey 30AB hammer mill, when paired with a 40 HP motor and used on hard rock ore, has a throughput that depends on several factors, including:

• Feed size • Ore hardness (e.g., quartz vs. caliche vs. decomposed granite) • Screen size installed • Desired product size General Output Estimate:

For hard rock ore (like quartz-bearing gold ore), and assuming average conditions:

• Estimated throughput: 1.5 to 3 tons per hour (TPH) • 1.5 TPH for dense, hard, coarse ore • Up to 3 TPH for softer rock or if finely pre-crushed Supporting Details:

• The Jeffrey 30AB is a medium-duty industrial hammer mill, commonly used in aggregates, coal, and gold ore crushing. • 40 HP is near the upper end of what this model usually handles, which maximizes RPM and impact energy but still limited by rotor size and chamber clearance. • If the ore is already pre-processed to below ~2” feed size, output improves. • With a 3/8” to 1/4” discharge screen, you’re more likely to get material in the ball mill feed range
