Through extensive research and development, CoalTech has identified a method of converting coal fines into cost efficient industrial-strength pellets by which the coal fines are bound together in the pelletizer plant using a special chemically-formulated binder.
In the pelletizing process for coal fines are rolled into balls of 5-50mm diam. The addition of 5 to 10 percent binder produces a product which after thermal drying, has sufficient stability to …
Pelletizing is a process that involves mixing very finely ground particles of iron ore fines of size less than 200 mesh with additives like bentonite and then shaping them into oval/spherical lumps of 8-16 mm in diameter by a pelletizer and hardening the balls by firing with a fuel.

Anthracite, often referred to as hard coal, is a hard, compact variety of coal that has a submetallic luster.It has the highest carbon content, the fewest impurities, and the highest energy density of all types of coal except for graphite and is the highest ranking of coal.
Unlike pelletizing, briquetting is a dry process, whereby pressure, instead of a binder, is used to form agglomerates. Here, coal fines are fed between two rolls, where they are put under extreme pressure, which binds coal particles to each other. The fines are pressed into the briquette shape. On occasion, it is desirable to use a binder in ...

Besides creating air pollution, coal fines pose severe problems in their dewatering, thermal drying, handling, transportation and storage. Pelletization, a model of agglomerating fine particles can alleviate some of these problems. This study was undertaken to ascertain the process and economic feasibility of the pelletization of fine coals.
The coal fines with peat are mix and the resulting well mixed mass is then pelletizing by the application of pressure in conventional equipment – stiff extrusion. The coal fines and peat was conditioned at various moisture contents to observe the effects on the finished product.

The chemical additive would have been similar to the type used to wet coal in the stacker/reclaimer system. The third method was a pelletizing operation that would convert the fines …
A coal agglomerate is produced by the combination of coal fines with a binder obtained by the direct liquefaction of biomass material. The direct liquefaction is carried out in the absence of oxygen at typical temperatures between about 450 and 700° F. and typical pressures between 200 and 3,000 psi, according to known liquefaction processes.
Fines generated during the screening of high-grade ore can be agglomerated in a sintering plant; however, the finer fines resulting from the beneficiation process cannot usually be processed in a sintering plant and must be agglomerated in a pelletizing plant. Therefore, a greater number of pelletizing plants are expected to be built in the future.

Abstract. The first step consisted of producing a batch of seed pellets (in the size range {minus}4.75+4.00 mm) by pelletizing of 200 g of ground coal with desired additives (surface active agents and binders) and moisture content for 800 revolutions.
For example, a fresh (run of mine) sample of coal will display different pelletizing growth kinetics than a weathered sample of the same coal. Since coal is a heterogeneous material, the oxidized product of coal is equally variable.
