I was wondering is anyone knows how to calculate the dynamic fluid viscosity for a slurry thats consists of 75% (NH4)SO4 and 25% Nickel by volume. We know thats its density is 3160kg/m^3.

Where is the liquid? You describe a mixture of two solids, ans write of a slurry.
If what you have is a mixture os ammonium sulfate solution at a given viscosity Mul, then an estimate of the solids-liquid mix is given by Kunitz
Mu(mix)=Mu(liquid)*(1+0.5 Vsol)/((1-Vsol)^4) where Vsol is the solids volume fraction.
Be careful on two points: The above correlation works best for low Vsol (<10%, you have 25%); also, the suspension is likely to be highly non newtonian, so there is no single value for a "viscosity"
