centimeters = 0.3048 which extends its wear life dramatically. • •u Liners work hardens by compressive forces and at any given time the work hardened face is only about 2-3mm. • • The speed at which the liner work hardens increases as the percentage manganese content increases; so12-14% work hardens slowest & 20-24% ...The impact crushing strength of rocks so determined is used to calculate the Bond crushing work index using the expression (3.9) ... Bond's crushing work index of gypsum. 3.4. A sample of granite passing a 7.5 cm square opening screen was suspended in a Bond's pendulum test. The length of the pendulum was 413 mm and the mass of hammers is ...Calculate the work index if 80% of the feed passes a 2-in screen and 80% of the product passes a 1/4-in screen. Question: 0.1 The power required to crush 125 ton/h of unknown material is 100 kW. Calculate the work index if 80% of the feed passes a 2-in screen and 80% of the product passes a 1/4-in screen.Bond Crushing Law: n = 1.5 . W i is Work index in KWh/ton and D in mm . Example 4: Calculate the Power required to crush 50 ton/h of coke given the following data: W i = 115.13 KWh/ton Feed particle diameter = 50 mm Product particle diameter = 15 mm. Solution: Pages: 1 2 3. Leave a Reply Cancel reply.Problem will be more complex if you want to use the crusher for crushing many cans at a time and you are picking them from a pile of garbage….you will fill some big number of cans (say 100 ...Calculate the work index if 80% of the feed passes a 2-in screen and 80% of the product passes a 1/4-in screen. Question: 0.1 The power required to crush 125 ton/h of unknown material is 100 kW.
