OIL & MINERAL PROCESSING ASSIGNMENT-
The requirement in this project is to produce the finest grind size possible from the circuit shown in Figure 1 without addition of more grinding units. Machine data are given in Table 1.
TASKS-
1. From the data given in Figure 1 and table 1, identify sources of spare capacity and potential areas for improvement for this grinding circuit.
2. Perform a mass balance on each unit by specifying the input and out flow rates in t/hr and the size distribution.
3. Write a Matlab code to predict the performance parameters, and product size distributions of the SAG, ball mill and the hydrocyclones. The user should input the capacity of the ball mill and the desired d50 size for the hydrocyclone. The code should then outputs the density of slurry, and the volumetric flow rate of the pulp, the cyclone size that is optimal for the imputed data, or all the cyclone sizes that will satisfy the imputed data at the user's choice.
4. The code must also output the feed distribution together with the resulting semi-log graph of mass % of feed material reporting to the underflow (U/F) versus the mean particle sizes (μm) on the sampling data shown in Table above. Label all axes and include comments in your Matlab code to describe your method.
5. Maximize the grind product size at a constant throughput of Nt/hr.
6. In case Nt/hr is too low or high, how can you increase or decrease throughput without making the final grind coarser.
Where N is the last three digits of your student number.

Calculate the overall energy content of the waste
: Determine the composition of the waste in Problem 2-17 if 10% of the wood waste, 50% of the paper, 30% of the metals, and 25% of the plastics are recycled. How would this affect the energy content.
