A spiral mine grading screen

Abstract

The invention relates to a spiral mining grading screen, which includes a base, a cylinder body, a controller, a recovery pipe, a feeding pipe, a water injection pipe, a feeding pipe, a collecting mechanism and several legs. There is a grading mechanism at the body, the breaking mechanism includes the first motor, drive shaft, transmission assembly, sealing plate, sealing block and two curved rods, and the collecting mechanism includes a collecting box, a water pump, a return pipe, an overflow pipe, and a discharge pipe and a collection assembly, the collection assembly includes a first collection net, a connecting rod, a second collection net and a support unit, the spiral mining grading screen breaks up the accumulated mineral materials through a dispersing mechanism, and separates the mineral materials according to a certain The speed is transported to the cylinder to avoid the accumulation of mineral materials which is not conducive to separation. Not only that, the collection mechanism is used to facilitate the collection of mineral materials with different specific gravity, and the collected water is transported to the cylinder through the return pipe through the water pump for grading operation, which reduces the The water consumption of the equipment is reduced, thereby improving the practicability of the equipment.

Description

technical field [0001] The invention relates to the field of mining development equipment, in particular to a spiral mining grading screen. Background technique [0002] Spiral mining grading screen is one of the mineral processing equipment, and its operation principle is to use the difference of solid particles, so the sedimentation speed in the liquid is different, so as to perform mechanical separation of a mineral processing equipment. It can filter the powder from the mill, and then use the screw to screw into the feed port of the mill, and discharge the filtered fine material from the overflow pipe, so it is widely used in the beneficiation process of mining. [0003] However, during the use of the existing spiral mining grading sieve, the ore powder is usually agglomerated when feeding, and at this time some ore particles with a larger specific gravity are easy to surround the ore particles with a smaller specific gravity, making the specific gravity larger. Small o...

Problems solved by technology

[0003] However, during the use of the existing spiral mining grading sieve, the ore powder is usually agglomerated when feeding, and at this time some ore particles with a larger specific gravity are easy to surround the ore particles with a smaller specific gravity, making the specific gravity larger. Small ore particles cannot float above the liquid surface, resulting in poor screening effect. Not only that, when the equipment is running, it is necessary to ensure sufficient water inside the equipment, which leads to huge water consumption of the existing spiral mining grading screen, and also Caused unnecessary waste of water resources, thereby reducing the practicability of the existing spiral mine grading screen
