Crushin gKODIAK PLUS AND LS CONE CRUSHER NOTES1. Capacities and product gradations produced by conecrushers will be affected by the method of feeding,characteristics of the material fed, speed of themachine, power applied, and other factors. Hardness,compressive strength, mineral content, grain structure,plasticity, size and shape of feed particles, moisturecontent, and other characteristics of the material alsoaffect production capacities and gradations.2. Gradations and capacities shown are based on a typicalwell-graded choke feed to the crusher. Well-gradedfeed is considered to be 90%-100% passing the closedside feed opening, 40%-60% passing the midpoint ofthe crushing chamber on the closed side (average ofthe closed side feed opening and closed side setting),and 0-10% passing the closed side setting. Chokefeed is considered to be material located 360 degreesaround the crushing head and approximately 6” abovethe mantle nut.3. Maximum feed size is the average of the open sidefeed opening and closed side feed opening.4. A general rule of thumb for applying cone crushers isthe reduction ratio. A crusher with coarse style linerswould typically have a 6 to 1 reduction ratio. Thus, witha 3 ⁄4” closed side setting, the maximum feed would be6 x 3 ⁄4 or 4.5 inches. Reduction ratios of 8 to 1 may bepossible in certain coarse crushing applications. Fineliner configurations typically have reduction ratios of4:1 to 6:1.5. Minimum closed side setting may be greater than publishedsettings since it is not a fixed dimension. It willvary depending on crushing conditions, the compressivestrength of the material being crushed, and stageof reduction. The actual minimum closed side setting isthat setting just before the bowl assembly lifts minutelyagainst the factory recommended pressurized hydraulicrelief system. Operating the crusher at above thefactory recommended relief pressure will void the warranty,as will operating the crusher in a relief mode(bowl float).34
