Note: This step comes after the initial crushing and when the coals are reduced in size. This is because screens cannot screen large coal, as their feed size is typically within 200 mm. Step 3: Grind the coal To conclude the coal pulverization procedure, we need to take the coal through a secondary grinding stage. This is an …

tests 1 to 4, each type of single coal was crushed to target particle size and then blended. In tests 5 and 6, the coals were blended in a predetermined ratio and then crushed into target particle size. The prepared coal was then charged into a test pail at a bulk den - sity of 850 dry kg/m3 and carbonized for 18.5 hours in the test coke oven.

This acceleration is limited in a range of particle sizes, 0.180−0.224 mm for lignite and 0.125−0.224 mm for anthracite. After the coal is crushed to 0.180−0.224 mm, the consumption of aliphatic hydrocarbon groups by the crushing process begins to weaken. −OH is the main reactive group in the coal crushing process.

Question: 1. The crushed coal has a diameter D = 5 mm. The density, specific heat capacity, and thermal conductivity of the coal are p = 1200 kg/m3, cp = 2400 J/kg.K, and k = 0.4 W/mK. The coal will be dried by increasing its temperature from Ti = 30 °C to Tf = 80 °C in a convection oven, where the coal is carried on a conveyor.

Moreover, some of the particles are re-crushed, and the voids are filled by the re-crushed smaller particles. The strain ending points for this compaction stage are 0.12, 0.16, 0.18, and 0.21 for the 2.5–5, 5–10, 10–15, and 15–20 mm crushed anthracite, respectively. This indicates that larger particles exhibit greater linear deformability.
