FIELD: mining.
SUBSTANCE: invention relates to mining industry and can be used for mechanized loading blast holes and wells with granulated explosives, particularly in design of mobile, portable and backpack pneumatic chargers. Device includes plate-type perforated aerator 1 installed in bin 2 base, and unloading pipe 3 installed above aerator 1. Unloading pipe 3 is made in the form of pipe of round section located horizontally. In upper part of pipe, starting from the edge itself, longitudinal slot 4 with length of 2.5–3 of pipe diameter is made. Unloading pipe 3 and aerator 1 are arranged parallel to each other. Aerator 1 can be made metal, or ceramic, or fabric.
EFFECT: simplified design, increased reliability and density of boreholes and wells charging with granulated explosives, as well as reduced weight of the device.
