Well, this is a tricky question. While I was searching alone I discovered it may be both, but I am not positively sure. You should be able to find the answer on websites that end with .edu

The grain size of coal can vary, but it typically ranges from fine particles to larger chunks. Coal can be classified based on its grain size as fine, medium, or coarse coal. The grain size of coal can impact its combustion efficiency and handling characteristics.
The grain size of bituminous coal typically ranges from 0.5 to 2 inches. It is considered a medium-grain size coal, with a balance of fine and coarse particles. The grain size can vary depending on the specific source and processing of the coal.
Bituminous coal has a smooth texture with a dark color. Its grain is typically fine to medium and can range from a banded appearance due to layering of different materials, to a more homogeneous structure.
Coal typically burns at temperatures ranging from 1,100 to 2,200 degrees Fahrenheit. The combustion temperature of coal is influenced by factors such as the type of coal, the amount of oxygen available for combustion, the size and shape of the coal particles, and the efficiency of the combustion process.
Coal is not typically used directly to make plastic. However, coal can be converted into various chemicals such as ethylene and propylene, which are important building blocks for plastic production. These chemicals are used in processes like polymerization to create different types of plastics.

They just used normal coal.
Coal generally has a fine-grained texture, as it is composed of small particles formed from the accumulation and compression of plant material over millions of years. The grain size can vary depending on the type of coal and its formation process, but it is typically characterized by a smooth, even appearance. In contrast to coarse-grained materials, coal's fine grain allows it to burn more efficiently.

Grain shape.
Pellet grain is really just the type of shape of the grain. Instead of flake grain it is just shaped like a pellet or, if you will, like a perscriptian drug.
Three characteristics of a rock's grain include size (fine, medium, coarse), shape (angular, rounded), and sorting (well-sorted, poorly sorted). These characteristics can provide information about the rock's origin and history.
The grain shape of marble is typically interlocking. This means that the individual mineral grains in the marble are tightly interwoven or interlocked with each other, forming a solid and dense structure.
