Barite (barium sulfate) is a mineral commonly used in drilling fluids, paints, plastics, and other industrial applications. Crushing barite requires robust machines due to its moderate hardness (3–3.5 on the Mohs scale) and density. Below are the most suitable barite crushing machines and processing steps:

1. Primary Crushing (Coarse Reduction)
– Jaw Crusher:
– Best for initial size reduction of large barite chunks (up to 1 meter).
– Adjustable discharge size (typically 10–350 mm).
– High crushing ratio and simple structure.
– Gyratory Crusher:
– Used in large-scale mining operations for high-capacity primary crushing.

re efficient than jaw crushers for very hard or abrasive materials.
2. Secondary Crushing (Intermediate Size Reduction)
– Impact Crusher:
– Suitable for medium-hardness materials like barite.
– Produces cubic-shaped particles, ideal for further processing.
– Cone Crusher:
– Provides finer crushing than jaw crushers.
– Adjustable settings for different output sizes (5–60 mm).
3. Tertiary/Fine Crushing (Particle Size Control)
– Hammer Crusher:
– Effective for smaller barite chunks, producing fine powder (<10 mm).
– Roller Crusher:
– Good for producing uniform particle sizes with minimal fines.
– Vertical Shaft Impact (VSI) Crusher:
– Produces finely crushed barite for ultra-fine grinding applications.
4. Grinding Mills (Ultra-Fine Powder Production)
– Raymond Mill:
– Common for grinding barite to 80–325 mesh (0.044–0.18 mm).
– Ball Mill:
– Used for wet or dry grinding to achieve very fine powder (<200 mesh).
– Ultrafine Grinding Mill:
– Produces micron-sized barite powder (D97 < 10 μm) for high-value applications.
Key Considerations When Choosing Barite Crushing Machines
1. Feed Size – Larger chunks require jaw/gyratory crushers first.
2. Output Size – Fine powder needs secondary/tertiary crushers + grinding mills.
3. Moisture Content – Wet crushing may
