Comminution

Separates material by particle size using screen openings to produce controlled feed and product fractions. Screen type, aperture, motion, and deck configuration are selected for capacity, efficiency, moisture conditions, and material characteristics.

Use centrifugal forces to classify slurry particles by size and density within mineral processing circuits. They commonly operate in closed grinding circuits, returning coarse underflow to the mill while sending fine overflow downstream.

Use controlled water flow and particle settling to classify or separate materials by size and density. They can remove fines, deslime feed, or produce controlled fractions for improved separation and downstream processing.

Reduces run-of-mine ore to a manageable size for conveying, stockpiling, and further size reduction. Crusher selection and circuit design depend on ore competency, feed size, capacity, product requirements, and downstream equipment.

Further reduces primary-crushed ore to prepare a controlled feed size for tertiary crushing or grinding. This stage improves size control, increases circuit capacity, and reduces the energy required in subsequent comminution stages.

Produces a finer, more uniform product for grinding, separation, agglomeration, or other downstream processing. Careful control of product size and circulating load supports consistent throughput and efficient downstream performance.

Reduces particle size without water to prepare dry feed for separation, blending, agglomeration, or thermal treatment. Equipment and operating conditions are selected to control particle size, energy consumption, dust, and product handling characteristics.

Reduces ore particle size in water to liberate minerals and prepare slurry for classification and separation. Mill selection, media, water balance, and operating conditions influence liberation, throughput, energy use, and downstream recovery.

Separates particles by size or settling behavior to control product size and improve downstream process efficiency. Effective classification returns coarse particles for additional grinding while directing correctly sized material to the next process stage.
