Automatic ring-cone-process uniform-mixing and division apparatus for dry bulk material

Abstract

The invention discloses an automatic ring-cone-process uniform-mixing and division apparatus for a dry bulk material. The apparatus comprises a feed inlet, a quaternary ring-cone uniform-mixing system and an annular outlet, wherein the quaternary ring-cone uniform-mixing system is composed a first ring cone, a second ring cone, a third ring cone and a fourth ring cone which are successively connected from top to bottom; the first ring cone, the second ring cone and the third ring cone are separately composed of a non-inverted cone and an inverted cone; the fourth ring cone is only composed of a non-inverted cone; each of the non-inverted cones and the inverted cones is composed of a larger outer cone and a smaller inner cone which are coaxial; and gaps functioning as passageways for the bulk material are formed between the larger outer cones and the smaller inner cones. The apparatus provided by the invention is simple in structure, allows materials to be rapidly and uniformly mixed in a short period of time after passing through the quaternary ring-cone uniform-mixing system, reduces influence of artificial objective factors on operation, lowers workload and mitigates harm of powder to human beings.

Description

technical field [0001] The invention belongs to the technical field of mining machinery, and in particular relates to an automatic ring-cone method mixing and shrinking equipment for dry bulk materials. Background technique [0002] Before the ore property analysis, process mineralogy research and ore dressing experiment, the original sample (all samples) taken should be broken and shrunk into many single samples. It can represent the entire original sample in terms of characteristics, so the mixing and shrinking operation is very critical. Currently, the commonly used mixing methods include the cone-moving method, the ring-cone method, and the tumbling method. Most of the mixing is done by hand. Manual mixing is often due to Due to manual operation, it cannot be completely mixed, which will affect the follow-up ore research. The commonly used ring cone method is to use a shovel to stack cones. When stacking cones, the sample must be lowered from the center of the cone so t...

Problems solved by technology

[0003] From the above description, it can be seen that the manual mixing and shrinking of the ring-cone method is difficult to eliminate the error of mixing and shrinking due to human and objective factors, and the workload is heavy, dust is easy to be generated, and the experimental environment is deteriorated.
