Machine Details Show
Description & Technical Data
The small hammer crusher (hammer mill) crushes by the collisions between high-speed hammer and materials, and its features are simple structure, high reduction ration, high efficiency, etc.
Working principle
The motor drives the rotor rotate at a high speed through the belt, and on the rotor there are series hammers. When the materials feed into the working area of hammers, they are crushed by the rotating hammers in high speed, the minerals which are crushed into the required size can be discharged by the outlet, and become the final products; while the large size products are brought back to the crushed area by the hammers to be recrushed until they reached the required size.

Frequently Asked Questions
Q: What is the smallest gold particle size this concentrator can recover?
A: It can recover gold particles as fine as 0.004mm, with a recovery rate of approximately 97% for this size fraction.
Q: How often do I need to clean out the concentrate?
A: The cleaning-up cycle is typically 1–4 hours for vein gold and 2–6 hours for placer gold, depending on the grade of your ore.
Q: Does this machine require chemicals?
A: No. The centrifugal concentrator uses only water and electricity. It is a completely physical separation process with zero chemical pollution.
Q: Can I use this concentrator for tailings re-processing?
A: Yes. It is widely used to recover fine gold from old tailings, grinding circuit discharges, and flotation concentrates where fine gold has not been fully captured.
