Study of the agglomeration process of various types of raw materials by extrusion method

The oxidation of materials on an industrial scale is used in the processing of various very different types of raw materials, represented by small particles. For example, agglomeration is used in the metallurgical industry, in the processing of coal, peat, agricultural products and much more. There are three main methods of agglomerationbriquetting, sintering, pelletizing. One of the most common devices for briquetting is roller presses. The main advantages of roller presses are their versatility, relative simplicity of design, relatively high productivity, small dynamic loads, compactness, sufficient reliability under significant mechanical and thermal influences. Another device that can be used for briquetting are various types of extruders, which have a number of advantages over roller presses. The paper proposes an easy-tomanufacture and cheap extruder suitable for the study of materials on “briquetability” by the extrusion method. The extruder belongs to the plunger type. In it, the material is squeezed out of the forming nozzle not under the pressure of the screw, but under the pressure of the piston, which is driven by a screw pair. Examples of the use of a plunger extruder for the manufacture of extrudates for metallurgical purposes from iron ore raw materials, steel filings, fuel briquettes from carbon-containing raw materials are given. The resulting extrudates are designed to study their physico-mechanical and other properties.

Keywords: agglomeration, sintering, briquetting, extrusion, plunger extruder, extruder design, extrusion briquette (extrudate), metallurgical briquette, fuel briquette, binders.
