·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 It is
An improved gyratory crusher is provided The gyratory crusher comprises an eccentrically rotating mantle lined with a mantle liner a concave lined with a concave liner the concave housing the mantle to provide a crusher chamber and the crusher chamber having a gap The improvement is a system for determining a close side setting for the gyratory crusher based on
The highest possible cone crusher efficiency is always sought In other words we are always looking to maximize productivity and utilization of crusher liners To achieve that it is essential to define the right time to change wear parts and understand the changes that occur in the volumetric cavity throughout the life cycle
·liners where the thickness is still sufficient to protect the shell It is crucial to point out that shell protection is only one function of the mill liner It also needs to optimise the grinding process Clinker grain sizes depend on pre crusher settings but are in some cases still up to 50mm when fed to the ball mill

·Wearing parts in the gyratory crusher may be either chilled cast iron or manganese steel depending on the character of the material to be crushed and the particular class of service for which the machine is intended Standard crushers in the small and medium sizes are customarily fitted with chilled iron head and concaves for crushing soft and medium
As the feed is crushed it falls and exits the crusher through the space at the bottom The eccentric gyration of the mantle means that at any moment this space is narrowest at one point and widest at the opposite point The widest distance is known as the open side setting OSS and the narrowest the closed side setting CSS
·Crusher Setting Adjustment Crusher setting can be changed mechanically by screwing the bowl or top shell or changed by direct hydraulic actuation of the crusher main shaft or through hydromechanical devices On some crushers setting adjustments can be made while the crusher is operating under load and some must have the feed temporarily
