choke feeding in crushing

Maximize your cone crusher productivity | Pit & Quarry

4. Ensure the feed is evenly distributed. The incoming feed material should be directed on a vertical plane into the center of the crusher. When the incoming feed is not directed into the center of the cone, one side of the crushing cavity could be quite full while the opposite side of the cavity could be low or empty.

1. Check the feed arrangement: • The crusher should be choke fed so that the crushing chamber is full all the time. 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

The purpose of the primary crusher is to reduce the ROM ore to a size amenable for feeding the secondary crusher or the SAG mill grinding circuit. The ratio of reduction through a primary crusher can be up to about 8:1. …

Best Practices for Cone Crusher Maintenance

Lubrication is one of the most important practices a cone crusher needs to avoid breakdowns because of the constant crushing actions the machine performs and the friction it creates. Good lubrication will minimize wear and tear, reduce component or equipment damage, and increase performance levels. ... Properly choke feeding the …

Choke-feed implies a completely filled crushing chamber (or as full as the design will permit), with a sufficient head of material above the receiving opening to keep the crusher full continuously. This contrasts with regulated-feed, which implies that the flow of material to the crusher is throttled to a point somewhat below the capacity of ...

Performance Monitoring for a Crushing Plant

Consequently, the ratio (0-100%) between efficient crushing time and total running time can be reported for any selected time period. This gives boost to efficient plant operations for a better productivity. Reports on non-choke or inadequate feeding. Non-choke feeding to crushers is avoidable through smart plant-wide crushing plant controls.
