General Method Of Activated Charcoal Briquetting Making Intr

AGICO is a professional charcoal briquette making machine manufacturer in China, listed below is the carbon briquetting making introduction:

Raw material pretreatment and preparation:

The selection and quality control of the raw coal, theoretically all kinds of coals can be used in activated carbon production, but almost all the coal processing plant in the world use more than 1 kind of coal in the production. The quality of activated carbon briquette made of single type coal is not very satisfying; 2-4 types of coal are used as a match in the commercial activated carbon production.

When anthracite, lignite or peat are used in the coal processing, water content, ash rate and evaporate rate are the 3 key figures for the following processing steps:

Solid Carbonaceous binder control: coal tar pitch is the best binder for improving the mechanic characteristics of carbon briquette product, the binder and coal powder rate range is about 10%-25%. The mechanic hardness of the briquette can be tested by letting the sample briquette product fall from the height of 2 meters, when the cracked pieces and particles which the sizes are smaller than 2mm weighs less than 25% of the total weight, the briquette hardness is good.
