Calculate the material passing the 3/4 in (19.0 mm) sieve. If the material passing the 3/4 in (19.0 mm) sieve is not within the Specification requirements, adjust the percentage of material passing the 0 (2.00 mm) sieve until the percentage of material passing the 3/ 4 in (19.0 mm) sieve is within the Specification requirements.The test is not applicable to sizes smaller than 6.3 mm. The flakiness index is taken as the total weight of the material passing the various thickness gauges expressed as a percentage of the total weight of the sample taken.

The screen analysis of the product was as follows:What would be the power required to crush 1 ton/h of the same material from a feed of - 4.44 cm + 3.81 cm to a product of average product size 0.051 cm? Use Rittinger's law.The material in the crusher is firstly crushed by the high-speed moving hammer. And then the material gets kinetic energy and goes to the crush plate at high speed and be crushed again. The particle size smaller than the grate bar will be discharged from the crusher machine, and the material size larger than the grate gap will be crushed again.

A primary crusher operates on run of mine material accepting anything that comes from the mine face and breaking into 150-250 mm (6-10 in). A Secondary crusher reduces these lumps into 6 mm (1/4 in). Grinders reduce crushed feed to powders The product from …It has been stressed that the coal supplier should initially crush the materials to a maximum size such as 300 mm, but they may be something else depending on the agreement or coal tie up. To circumvent the situation, the CHP keeps a crushing provision so that coal bunkers receive the materials at a maximum size of about 20-25 mm.If a material consisting of originally 30 mm particles is crushed to an average of 5 mm and requires 30 kJ/kg for this size reduction.
