Abstract
An activation unit for explosive masses or explosive bodies includes an ejector tube and high-performance heating elements mounted around the ejector tube, each made of at least one heating wire supplied with electrical power by a control unit. Each heating wire is enclosed in a casing and embedded in a material minimizing heat loss. When the explosive body is passed through the activation unit, the jacket surface of the explosive body contacts the individual elements of the activation unit in a direct or non-contact manner. Thermal energy is transferred to the explosive body by means of the heating wires, and the body ignites at the contact points. A further activation unit includes heating elements in the ejector tube, at least partially fed longitudinally through the ejector tube, made of heating wire clad with CrNi steel and contact plates soldered thereto.
