Nip Angle and Its Use. Feb 12 2008 · Jaw Crusher Nip Angle The nip angle describes the angle the stationary jaw plate and the pitman make with each other The exact value of this angle isnt quoted or even determinable due to curvature in the jaws themselves but what is important is how wide vs narrow it is Wide nip angles can tend to expel material as the jaw closes as a large
· 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:
