An automatic ring-cone mixing and shrinking equipment for dry bulk materials

Abstract

The invention discloses an automatic ring-cone mixing and shrinking equipment for dry bulk materials, which includes a feeding port, a four-time ring-cone mixing system, and a ring outlet; the four-time ring-cone mixing system consists of the first The first ring cone, the second ring cone, the third ring cone and the fourth ring cone are connected sequentially from top to bottom; the first ring cone, the second ring cone and the third ring cone are composed of An upright cone and an inverted cone are formed, and the fourth annular cone is only composed of an upright cone; both the upright cone and the inverted cone are composed of a larger outer cone and a smaller The inner cone, the outer cone and the inner cone are coaxial, and there is a gap between the inner cone and the outer cone as a channel for bulk materials. The invention has a simple structure, and the material can be quickly mixed in a short time after passing through the four-time ring-cone mixing system, which reduces the influence of human and objective factors on the operation, and reduces the workload and the harm of dust to the body.

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.
