s is jaw throw, m; a is the nip angle; k is a material factor, 1.5 to 2.0 (includes your epsilon param) N is RPM; This form works out volume of one motion of the jaw, multiplies by RPM then multiplies again by 60 to give volume/hour. This looks better, but it still doesn't work. Example, C80 jaw crusher, 2″ CSS:
