Coal Blending. Coal blending is a process of uniformly combining two or more kinds of coking coal in appropriate proportions to obtain the required blended coal. It is a preparation process of coal charges before coking. Coal blending can ensure the quality of coke meets the requirements and also can reasonably utilize coal resources.

Coal homogenization Wikipedia

Coal homogenization Wikipedia

Coal homogenization refers to the process of mixing coal to reduce the variance of the product supplied. This homogenization process is performed during the coal stockpiling operation. Although the terms blending and homogenization are often used interchangeably, there are differences, as the definitions show.
