Description

Technical Field

[0001] The utility model belongs to the technical field of spiral chutes, and in particular relates to a spiral chute for efficient ore dressing. Background Art

[0002] A spiral chute is a device used for mineral processing. It uses the effects of gravity and centrifugal force to cause mineral particles of different densities to be stratified in a rotating spiral chute, thereby achieving mineral separation. Specifically, a spiral chute is usually composed of one or more spiral chutes and a feed port, a tailing port, and a washing port perpendicular to the spiral axis. The pretreated ore material is added to the spiral chute from the feed port. Under the action of centrifugal force and gravity, the heavier mineral particles slide downward along the spiral chute and rotate along the tangential direction of the chute, and are finally discharged from the tailing port, while the lighter mineral particles move upward along the spiral chute and are discharged from the washing port, thus achieving mineral separation. In practical applications, spiral chutes are usually used in mineral processing, coal processing, and gangue discharge.

The high-efficiency spiral chute for mineral processing, through the design of the first screen plate, the second screen plate, the bottom frame, the push rod, the rubber ball and the cylinder, enables the device to automatically classify the ore, and can collect ores of the same volume together without manual screening, so that the screening effect of the device is more efficient, and the ore can be classified more quickly, which reduces the workload of the staff and improves the practicality of the device; however, the structure of the above-mentioned high-efficiency spiral chute for mineral processing is relatively simple, and the material can only be loaded through the loading port at the top, and the loading effect is not ideal, and there is a possibility of blockage, which affects the use efficiency and user experience, and the screening mechanism of the device needs to collect and clean the material regularly when in use, and cannot operate stably for a long time, lacks the conditions for flexible adjustment, and the overall practicality of the device is poor. Therefore, it is necessary to provide a spiral chute for high-efficiency mineral processing to solve the above problems. Utility Model Content
