Optimal feed arrangement — SRP TON Group

The optimal arrangement for a cone crusher is to choke feed it with a non-segregated feed. This will help the crusher run more smoothly by lowering both power and pressure peaks and improving overall performance. Choke feeding is about maintaining a constantly high level of evenly distributed material in the feed

Selecting crushing chambers for cone crusher TON

2020-4-7  Feed should always be well graded with no gaps in the size distribution, which generally means an even distribution of different-sized feed material up to the defined maximum size. Fines (for example, 0–4 mm) should be screened out before the material is fed to the crusher as the fines may cause packing: this is a force overload and can be
