This is important, especially in fine crushing. Choke feeding maximizes the amount of multi-layer crushing, improves the shape of the crushing cavity as it wears and improves the crushing efficiency. => Choke feed level for an HP cone crusher is 300 mm or more above the feed plate. • The feed must be distributed evenly 360º around the crushing
Details
A crusher with a high choke-point incorporated in its design is not appreciably affected by choke feed. When these crushers are fully buried, the choke-point throttles back the material so as to prevent overloading the lower part of the crushing chamber, and there is so little active crushing surface above the choke-point that very …
Details
The reduction ratio is driven by the Crusher Close Side Setting. The actual minimum safe closed side setting of a crusher will vary somewhat, for any given crushing machine, depending upon the character of the material, the amount of fines in the feed, and whether the crusher is being operated under choke-feed or regulated feed conditions. …

However, the CSS is set manually by an operator. Operating cone crushers at the choke-feed point is recommended by manufacturers because this approach gives a more consistent product sizing, maximizes throughput, develops a uniform wear profile, and extends the liner life (Bearman and Briggs, 1998, Ma et al., 2016).
