The possibility of producing pitch coke from moderate-temperature pitch with the introduction of 10–30% dusty carbon fillers is investigated. The influence of graphitized dust and coal dust on the yield and quality of pitch coke is demonstrated.
Pitch coking determines the quality of pitch coke, which ultimately affects the quality of a carbon anode. In this work, green carbon anodes were studied by scanning electron microscopy (SEM), and the pitch pyrolysis process was tested using a custom-built pyrolysis device. The influence of the coke size on pitch pyrolysis was examined and …

Stone burr mills are the most traditional and produce an exceptionally fine quality of flour. Mills use a pair of grinding stones made from a durable material, such as granite or a similar material, to slowly grind the grains into flour. This method ensures a consistent texture and preserves the nutritional value of the grain.
Pitch coke (PC) is manufactured by the carbonization at temperature equal to or higher than approximately 450 °C of coal-tar pitch as a raw material withdrawn from the bottom of a distillation column in which coal tar is described. The majority of PC is processed for making a carbon or graphite electrode. PC is used as a raw material to ...

Table Source: Wikipedia (Crushers) Cone crushers use a spinning cone that gyrates in the bowl in an eccentric motion to crush the rock between the cone surface, referred to as the mantle, and the crusher bowl liner.Gyratory crushers are very similar to cone crushers, but have a steeper cone slope and a concave bowl surface. As the gap …
Dry grind mills also are used to make dispersion strengthened metal (DSM). In this process (known as mechanical alloying or cold welding) the grinding media break the metals and additives into small particles first, and then beat them together to form agglomerates. Repeating the process evenly mixes and disperses the various metals to …
