Description

Technical Field

[0001] The utility model relates to the technical field of waste recycling of detonator shells, and particularly relates to a crushing mechanism for waste detonator shells. Background Art

[0002] Detonator products are applicable to deep hole initiation in various mine blasting operations. By placing a detonator at the bottom of a medium-depth blast hole, the explosive in the blast hole is detonated to achieve the blasting operation. When detonating in this way, the explosion occurs from the inside out under the closed state at the bottom of the blast hole, which can minimize the loss of detonation energy and improve the blasting effect, and is widely used in various occasions that require blasting operations.

[0003] Most of the existing detonators are in the form of shells made of materials such as polypropylene and polyethylene during production. However, some defective shell molds will be produced during the production of detonator shells. These shell molds can be recycled and reused by melting to produce new shell molds, which improves the material utilization rate. But because most of these defective molds are relatively complete materials, if directly melted, it will cause the waste to melt slowly, resulting in a decrease in the quality of the original molten material, and further leading to a decrease in the quality of the subsequent produced detonators. To solve the above problems, a crushing mechanism for waste detonator shells is proposed to solve the above problems. Content of the Utility Model
