Industrial Coal Coke Briquette and Its Making Process www.ecostan.com



Industrial coke is prepared of crushed coal as waste material, treated by coals blending and then briquetting to briquette. Basically, raw coke briquette primarily utilizes a coke briquette press machine with kinds of cold briquetting press or hot briquetting roller press. Introduction


Pre-heat treatment is carried out before briquetting for the coal material adopting the hot briquetting technology. That is the low-temperature carbonization process so that the coal raw material can be briquette in the unstiffening temperature range. Hot Briquetting Roller Press Process


If the waste coal material is a twocomponent, then the chief raw coal should be unified, it is initially carbonized at a low temperature, and in its unstiffened state, the secondary constituent coal ought to be consistently blended into the hot coal before briquetting by the hot roller briquette machine.


The cold briquetting process doesn’t need heat-up of the waste coal material. Cold briquetting is obtainable in two ways binder less way and the binder way. The lignite cold briquet-making process is a typical example of a cold briquetting process without a binder. Cold Briquetting Process


The characteristics of lignite are plastic and soft, and a high-strength briquette is ready by external force extrusion when lignite is used as raw coal. This kind of coal can be manufactured into lignite coke by coking.
