Powdery emulsion explosive blocky material crushing device

Abstract

The invention discloses a powdery emulsion explosive blocky material crushing device. The powdery emulsion explosive blocky material crushing device comprises a shell, a first pair of rollers, a second pair of rollers, a third pair of rollers and a conveying belt, a feeding port is formed in the upper end of the shell, a discharging port is formed in the lower end of the shell, an upper cover is installed at the feeding port, the conveying belt is installed below the discharging port, and the first pair of rollers, the second pair of rollers and the third pair of rollers are sequentially installed in the shell from top to bottom. Blocky materials are treated through the first pair of rollers, the second pair of rollers and the third pair of rollers, so that the blocky materials with different lumpiness are treated into powder, and the cost and the labor are saved; the distance between the first pair of rollers, the distance between the second pair of rollers and the distance between the third pair of rollers are adjustable, so that the blocky materials are gradually crushed, the situation that due to the fact that the difference between the lumpiness of the blocky materials and the distances between the rollers is too large, the materials are difficult to descend and enter a rolling part and need to be manually pounded, and potential safety hazards exist for workers is prevented, and the crushing efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of emulsion explosive production, in particular to a pulverizing device for powdery emulsion explosive block material. Background technique [0002] Nowadays, powdery emulsion explosives are widely used in industrial fields, with stable and reliable performance and certain water resistance. However, because powdery emulsion explosives belong to ammonium nitrate explosives, ammonium nitrate is easy to agglomerate, and it also appears in powdery emulsion explosives. There are two main ways for the generation of raw material: one is that during the production process, it is bonded to the wall of the pipeline and the wall of the milling tower to form a block with a certain thickness; the other is that it is caused by long-term stacking and extrusion during the storage process in the warehouse. It is very difficult to deal with bulk materials. There is no equipment to deal with them. It depends on manpower to bre...

[0002] Nowadays, powdery emulsion explosives are widely used in industrial fields, with stable and reliable performance and certain water resistance. However, because powdery emulsion explosives belong to ammonium nitrate explosives, ammonium nitrate is easy to agglomerate, and it also appears in powdery emulsion explosives. There are two main ways for the generation of raw material: one is that during the production process, it is bonded to the wall of the pipeline and the wall of the milling tower to form a block with a certain thickness;

It is difficult to deal with bulky materials. There is no equipment to deal with them. It depends on manpower to break the large pieces into small pieces or powder, which not only increases labor, but also reduces the crushing efficiency.
