Ultrasonic device for intensification of extrusion process of fibrous material

Abstract

In the conditions of economic crisis the most actual technologies are technologies used local materials or waste as a fuel. The technological equipment for pressing of fuel briquettes from fibrous materials (straw with flammable powder) was developed. It allowed to transfer mechanical vibrations of high-intensity ultrasonic frequency on the press-form and provided the quality improvement of produced fuel briquettes.
