Which cone crusher chamber for kyanite 88 tph in Brazil

For kyanite processing in Brazil – with major deposits in the states of Minas Gerais, Bahia, and Goiás – a 88 tph cone crusher is a key asset for secondary or tertiary crushing. Kyanite is an aluminosilicate mineral with a Mohs hardness of 4‑5.5, but it can be highly abrasive and has a tendency to form elongated crystals. Selecting the right cone crusher chamber directly affects product shape, liner wear, and downstream processing efficiency. Knowing which cone crusher chamber for kyanite 88 tph in Brazil helps you optimize recovery while controlling operating costs. OCP Mechanical Company, a factory‑direct manufacturer with over 40 years of experience, supplies Type C cone crushers with multiple cavity profiles for Brazilian hard rock, backed by 24/7 online support.

Fine cavity – a widely used choice for kyanite

For typical secondary or tertiary crushing of kyanite ore (feed size 30‑70 mm, target product 8‑15 mm), a fine cavity short‑head cone crusher is a practical configuration. The fine cavity has a moderate parallel zone length and a steep crushing angle, producing a cubical product with acceptable flakiness. When evaluating which cone crusher chamber for kyanite 88 tph in Brazil, a fine cavity operating at a CSS of 8‑12 mm can deliver 80‑100 tph of minus 10‑15 mm product. Many Brazilian kyanite operations have successfully used fine cavity crushers, reporting stable throughput and liner life of 1,000‑1,800 hours with Mn18%+Cr liners.

Extra fine cavity – for very fine product requirements

If your downstream process (e.g., flotation or calcination) requires a product P80 below 6‑8 mm, an extra fine cavity may be considered. This cavity features a longer parallel zone, which increases compressive force and produces finer particles. However, the extra fine cavity is more sensitive to feed size and moisture. For kyanite with high quartz content, the extra fine cavity can accelerate liner wear significantly – life may drop to 700‑1,200 hours. It is recommended only for operations where the value of the finer product justifies higher wear costs. A CSS of 4‑8 mm is typical. Many Brazilian kyanite processors find that a fine cavity followed by a screen achieves the required size without the wear penalty of an extra fine chamber.

How cavity selection affects liner wear and power draw

When you decide which cone crusher chamber for kyanite 88 tph in Brazil, consider the trade‑offs:

• Fine cavity – Moderate wear. Mn18%+Cr liners typically last 1,200‑1,800 hours. Power draw: 0.8‑1.2 kWh per ton.

• Extra fine cavity – Higher wear. Liner life 700‑1,200 hours. Power draw: 1.0‑1.5 kWh per ton (20‑30% higher).

• Standard cavity – Not recommended for fine crushing; produces coarser product (P80 15‑25 mm). Use only as a secondary stage before a fine cavity.

For most Brazilian kyanite operations, the fine cavity offers the best balance of product quality and operating cost. Upgrading to Mn18%+Cr liners (instead of Mn14%) extends life by 30‑50% and is highly recommended.
