Technical Field

The utility model relates to the technical field of mineral separation ball milling devices, in particular to a ball mill returning charge treatment device and mineral separation equipment.

Background

In the mineral separation process, a ball mill is generally adopted to initially grind slurry formed by materials with granularity smaller than or equal to 16mm and water. The particle size of the materials subjected to preliminary grinding is less than or equal to 7.5mm, and the particle size of the materials subjected to preliminary grinding is between 7.5 and 12 mm. The ball mill is provided with an outlet rotary screen, and the aperture of the outlet rotary screen is 7.5mm. Materials with the granularity of less than or equal to 7.5mm enter the ore pulp tank through the outlet drum screen, and the materials with the granularity of 7.5-12 mm are called returning materials, and the returning materials are required to be subjected to returning treatment.

However, the conventional practice has the following problems:

1) Because the high-level fall of the top end and the bottom end of the three-level belt is larger, the three-level belt is required to be matched with a trestle and a large platform for standing operation of workers, so that the cost of the ball mill return processing device is higher, and the workers need to stand on the trestle and the large platform for operation, thereby reducing the production safety and the production convenience;

2) The traditional ball mill returning charge processing device comprises a ball mill, three-stage belts, trestle bridges, a large platform and an ore pulp tank, wherein the three-stage belts have larger occupied area, so that the ball mill returning charge processing device has larger occupied area;

3) When the material is conveyed on the three-level belt, a phenomenon that a small amount of returning materials scatter everywhere and roll off easily occurs, and then potential safety hazards are caused, namely production safety is poor, the difficulty of cleaning the three-level belt is improved, and production convenience is further reduced.
