Abstract: An installation for explosive treatment of materials comprises a chamber for accommodation of a work table supporting a material to be treated and an explosive charge. An opening is provided in the chamber wall, and the work table is mounted for reciprocations through the opening for introducing the table into and withdrawing it from the chamber. The work table is made in such a form that it tightly seals the opening upon introduction into the chamber. The chamber walls adjacent to the opening are inclined with respect to the horizontal plane at an angle which is greater than the angle of friction of the material being treated with the chamber walls. Thus, the treated material is fed under gravity to the work table when the table is withdrawn from the chamber.The construction of such installation gives an opportunity to automatize the process of explosive treatment of materials thereby considerably improving its productivity.
