Carbon black undergoes pulverization inside a_______________?
Show answer Hide answer
Answer: B. Ball mill
Explanation
Carbon black is an extremely light, fluffy material requiring specialized densification. Ball mills provide the necessary tumbling and cascading action to pulverize and densify it. Option B correctly identifies the ball mill as the equipment used for carbon black. Carbon black reinforcing pigment has a very low bulk density in its raw fluffy state. Handling fluffy powders creates severe dust control and volumetric storage challenges. Tumbling grinding media break down agglomerates and pack the carbon structure tightly.
Rubber and tire manufacturing industries require densified carbon black for easy compounding. Pelletizing and ball milling operations improve the flowability of industrial pigments. Controlling dust during carbon black processing protects worker health and facility cleanliness. Hammer crushers would pulverize brittle minerals but fail to densify fluffy carbon black. Roll crushers are unsuited for handling extremely light, dusty, low-density pigment powders. Gyratory crushers process massive mined rock feeds rather than fine chemical pigments.
