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, and improves wear shape and crushing efficiency. 1. Choke feed level for GP secondary crusher is at the level of the

A cone crusher must always be choke-fed in order to maintain the highest levels of capacity, gradation, and cubical output. A surge bin (or hopper) and feeder that are placed before the crusher work best to maintain a choke-feed to the cone crusher. Without a hopper and feeder, it is nearly impossible to achieve choke-feeding.

They are compression crushers that generally provide reduction ratios of 6-to-1 to 4-to-1. Cone crushers are used in secondary, tertiary and quaternary stages. With proper choke-feed, cone-speed and reduction-ratio settings, cone crushers will efficiently produce material that is high quality and cubical in nature.
