[0034] The working principle of the ore sample crushing device for geological and mineral exploration in this embodiment is:

[0035] The first crushing mechanism performs the initial crushing of large ore samples, which are then screened by the first screening mesh 3. Ore with smaller particle sizes is screened by the first screening mesh 3 and then subjected to secondary crushing by the second crushing mechanism. Ore with larger particle sizes is screened by the first screening mesh 3 and discharged through the first discharge port 4. It is then put back into the first feed port 2 and subjected to the first crushing process again by the first crushing mechanism, resulting in ore with uniform particle size that undergoes secondary crushing by the second crushing mechanism. Ore samples crushed by the second crushing mechanism, screened by the second screening mesh 8, and ore samples with a particle size that meets the requirements fall onto the second guide plate 10 and are discharged through the second discharge port 5 under the action of gravity.
