CONE CRUSHER FEED DISTRIBUTOR AND METHOD -

The method of operating a cone crusher which includes gyrating a crushing cone within a crushing zone about a generally vertical axis, traversing a downwardly and outwardly extending feed zone about the axis of the crusher cone while feeding material to the upper end of the feed zone generally along the axis of the cone, discharging the material from the lower, outer end of the feed zone, retaining a layer of

Practical considerations on improved feeding

2016-1-12  A common feed method, but unless considerable care is taken, possibly the most unsatisfactory method of feeding cone crushers. Material is segregated by the “tamping” action of the idler sets as material passes over. Belt speed. 1. Material leaving the end pulley follows a parabola. The path depends on the speed of the belt. 2.

Crusher in-feed conveyor method and apparatus -

In-feed conveyors for rock and aggregate processing equipment, such as crushers, are typically configured to be in line, such that they transport material to be crushed from a first end of the crusher and deposit the material in the crusher for size reduction.

2016-1-1  The quantity of feed actually crushed is determined by subtracting the feed undersize from the total quantity of feed. The reduction tonnage term is dependent on the properties of the material crushed so that for a given reduction ratio, the crusher capacity will vary for different materials.
