Abstract

PURPOSE: To obtain coal pellets inexpensively, having strength and pressure resistance to stand transportation by pipe line and improved dehydrating properties, by adding a binder of surface active agent-containing emulsified oil to powdery or granular coal rolling in a granulator.
CONSTITUTION: An emulsifying agent (a mixed surface active agent of a nonionic type and an anionic type surface active agents) is added to fuel oil C, heated at 60W70°C, which is stirred by a homogenizing mixer, water is added to the blend, which is further stirred, to give an emulsified oil. Powdery or granular coal is continuously fed to a nucleus producing zone in the sloped rotary tray 3 of the dry type granulator 2, the emulsified oil is sprayed on it by the compressed spray nozzle 7, to give the desired oil-containing coal pellets. In the operation, several kinds of emulsified oil having different concentrations are prepared, and preferably sprayed while observing granulating conditions.
