ABSTRACT:
A device for briquetting loose materials with the use of impulse energy of detonation, in which there is provided a bed plate on which are mounted movably a housing and an anvil. The housing accommodates an explosion chamber and a first actuating cylinder space communicating with the chamber, with the cylinder rod carrying a plunger. Both the housing and the anvil are mounted on the bed plate with a possibility of rolling back at the moment of explosion along the axis of the first actuating cylinder towards its rod, and arranged in succession intermediate of the housing and anvil are a container having a through axial conduit for material to be briquetted, in which at the moment of explosion, the rod with the plunger are moving, and a die which is integral with the container and in which a briquette is formed under the pressure of the plunger, with the container and the die being aligned axially with the first actuating cylinder. The anvil accommodates actuating cylinders whose axes are parallel to that of the first actuating cylinder, and are spaced at the same distance from its axis with the rods of the actuating cylinders being rigidly connected to the die, and with the container and the first actuating cylinder being each adapted to receive its counterpart member, as required. As a result, during the forward stroke of the rods of the actuating cylinders accommodated within the anvil, the plunger pushes out the finished briquette from the die and during their back stroke the container with the die return the their initial position. The device has a greater output as compared with the known arrangements since it enables auxiliary operations associated with setting the device for the briquetting process to be carried out simultaneously.
