On May 8, 2026, information from the State Intellectual Property Office showed that Chengyuan Mining Development Co., Ltd. successfully applied for a patent titled “A spiral chute mining device for mineral processing system”. The authorization announcement number is CN224194928U, and the authorization announcement date is May 5, 2026.
Its application number is CN202521096535.3, the application publication date is also May 5, 2026, and the application date is May 29, 2025.

This patent relates to the field of mining equipment technology.
The utility model discloses a spiral chute mining device for a mineral processing system, which includes a main body, a rotating shaft, a spiral chute, a feeding hopper, a water adding hopper, an ore separation component, a material receiving chute and a driving component.
The main body is cylindrical with a hollow interior. The rotating shaft is coaxially connected to the main body. The spiral chute is arranged outside the rotating shaft and coaxial with the rotating shaft.
The hopper and the water hopper are both arranged on the top of the main body and are opposite to the spiral chute.
The ore separation component is arranged at the outlet end of the spiral chute and is used to divide the spiral chute into multiple flow channels; a plurality of material receiving chambers are provided in the material receiving chute, located below the spiral chute, and the multiple material receiving chambers respectively correspond to the multiple flow channels of the spiral chute; the driving component is used to drive the rotating shaft to rotate.
One of the highlights of this device is that it can adjust the ore separation components according to the actual slurry stratification situation and change the size and position of the slurry outlet, thereby significantly improving the sorting accuracy.
