control of closed side setting and throw of jaw crushers

Gyratory Crusher

With coarse or primary crushers, the 'open' side settings determine the size of the crushed product and this product contains a proportion of pieces corresponding in size to the opening at its widest; with fine crushers, which are also known as secondary crushers, on the other hand, the shape of the crushing part of the machine and the speed of rotation prevent the …

Estimate Jaw Crusher Capacity

W is inner width of crusher, m; S is open side setting, m; 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.

A Detailed Overview of Cone Crushers and What You Need to Know

The closed side setting determines what the final size of the particles will be and that setting can be adjusted until you've reached the desired material size. Usually, these crushers deliver a 4:1, 5:1, or 6:1 reduction ratio. As you reduce the closed side setting to produce smaller material, you also reduce the capacity of the machine.
