The thickness at the front of the cone is such that local buckling occurs and fragments of material break away due to bending stresses As crushing progresses the increased wall thickness allows progressive crushing of the cone without buckling and bending failure Figure 17 shows the final crushed state of the cone
A penetration tool comprising a 60° cone with a base dia of 50 mm operated at a rate of penetration of 30 mms has been adopted as standard for routine clod strength measurements made in the study of potato harvesting problems In this form the penetrometer has been used to test more than 16000 clods
• Compressive Strength • Toughness • Density • Friability • Plasticity • Feed Gradation • Moisture Content A measure of the amount of crush achievable for a particular crusher application is the reduction ratio A cone crusher with coarse Standard Head liners will typically be capable of a 6 1 up to 81 reduction ratio Fine
Except for the crushing pit area L 1 formed by direct crushing the residual strength of the rock in the compaction area is very small and it is easily peeled off at the bottom of the well after subsequent scraping However the residual strength in the crack growth zone also decreases significantly and it is easy to form bulk fractures
Crushing strength is defined by the International Fertilizer Development Center as the resistance of granules to deform or fracture under pressure IFDC 1986 Crushing strength is especially helpful in gauging handling and storage properties of a granular material and determining the pressure limits applied during bag and bulk storage
Moreover a comparison with the 3PB test shows that the strength measured in crushing is lower and the scatter of the data is larger than the ones obtained in bending This is a consequence of a Weibull size effect and of the presence of macrodefects within one type of the tested supports
Here is cone crusher arranged with a Level Sensor interlocked with the feed conveyor It keeps the crusher feed cavity full for best choke feeding This is a great way how you can choke feed a cone and crush for a finer product You do know that choke feeding reduces liner wear See why in this video I often see operators running their crushers at 65 percent It seems to be a common comfort
