• How to Choose the Right Chamber for Sandvik CH870 Cone Crusher Liners?

  Aug 20, 2026

  The Sandvik Hydrocone H7800 crusher is a high‑capacity, heavy‑duty hydraulic cone crusher widely used in large‑scale quarrying, mining, and aggregate production lines. Its overall crushing performance, hourly output, finished product grain shape, and Sandvik Rock Crusher CH870 liner service life heavily depend on one critical factor: Sandvik Stone Crusher CH870 cavity selection. Most quarry operators commonly struggle with uneven liner wear, frequent crusher blockages, poor aggregate shape and unexpected downtime — very often caused by mismatched cavity profiles.   What Chambers Are Available for CH870?     EC Extra‑Coarse: Largest feed opening, deep receiving zone, secondary crushing, big feed material, pursue maximum throughput   C Coarse: Econdary / early‑tertiary, large‑medium feed size, high tonnage aggregate plant   MC Medium‑Coarse: MC Medium‑Coarse: Most‑popular general‑purpose cavity, balance of feed acceptance, capacity and product gradation   M Medium: Tertiary crushing, medium feed, produce well‑shaped 20‑31mm aggregates   MF Medium‑Fine: Fine tertiary, smaller CSS, cubical aggregate for concrete   F Fine: Pebble crushing & fine tertiary, limited feed size, small finished material   EF Extra‑Fine: Quaternary / pebble crushing, smallest allowable feed, ultra‑fine finished product     Core Rules to Select CH870 Chamber   Match crushing stage 1. Secondary crushing: Select EC / C: handle large incoming run‑of‑mine or primary‑crushed rock 2. Tertiary crushing: Select MC / M / MF, most aggregate production lines   3. Pebble /quaternary: Select F / EF, strictly control max feed size entering chamber   Feed size rule 1. Maximum feed entering crusher should not exceed 80% of cavity nominal feed opening. 2. If oversized material keeps feeding into a fine cavity: frequent bridging, blockage, rapid one‑sided liner wear.   Closed‑Side Setting (CSS) matching 1. Each cavity has its minimum working CSS. Do NOT run CSS smaller than cavity minimum value. 2. Running too tight CSS on coarse cavity leads to packing, high power draw and drastically shorten liner lifespan.   Material hardness 1. Hard, abrasive rock (granite, basalt, iron ore): choose slightly coarser cavity, avoid over‑crushing inside chamber. 2. Soft rock (limestone): can run relatively fine cavity for good product shape.   Typical Field Mistakes 1. Use one cavity for all conditions: keep using EC cavity when feed size drops, output fine product with poor grain shape. 2. Run fine cavity with oversize feed: liners wear uneven, frequent downtime. 3. Ignore eccentric throw cooperation: cavity profile must work together with eccentric throw to get target tonnage.
