Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of ore dressing, specifically to an automatic feeding device of an ore dressing shaking table. BACKGROUND

[0002] The ore dressing shaking table is a common sorting equipment in the ore dressing industry, and its working principle is that under the action of transverse water washing and bed surface longitudinal shaking, fine particles of heavy minerals move to the concentrate end at the maximum speed, and move to the tailing section (transverse) at the minimum speed, and the movement speed of coarse particles of light minerals is just the opposite. The movement of other types of particles (excluding sludge) is between the two. As a result, different properties of particles move in different directions, and fan-shaped zoning is formed on the bed surface. After the concentrate end and the tailing section are connected, concentrate, middling, tailings and sludge are obtained.

[0003] In the slag comprehensive utilization project, the ore dressing shaking table is usually used to separate the metal in the slag, but due to the instability of the upper treatment process, the shaking table feeding is uneven, when the shaking table feeding is too large, the shaking table surface is too much, and the material is accumulated. In addition, due to the fact that the upper treatment process of the shaking table contains a large amount of water, when the water directly enters the shaking table, the water amount of the shaking table surface is too large, the water flow impact is too large, and the shaking table separation effect is affected, therefore, the utility model provides an automatic feeding device of an ore dressing shaking table.
