# How to Calculate and Solve for Capacity of Jaw Crusher | Mineral Processing

**Last Updated on November 21, 2021**

The image above represents capacity of jaw crusher.

To compute for capacity of jaw crusher, three essential parameters are needed and these parameters are **Gape Size (G), Width of Crusher (W)** and** Closed Single Setting of Jaw Crushers (CSS).**

The formula for calculating capacity of jaw crusher:

C_{JC} = ^{G.W} / _{CSS}

Where:

C_{JC} = Capacity of Jaw Crushers

G = Gape Size

W = Width of Crusher

CSS = Closed Single Setting of Jaw Crushers

Let’s solve an example;

Find the capacity of jaw crusher when the gape size is 10, the width of crusher is 8 and the closed single setting of jaw crusher is 14.

This implies that;

G = Gape Size = 10

W = Width of Crusher = 8

CSS = Closed Single Setting of Jaw Crushers = 14

C_{JC} = ^{G.W} / _{CSS}

C_{JC} = ^{(10)(8)} / _{14}

C_{JC} = ^{(80)} / _{14}

C_{JC} = 5.71

Therefore, the **capacity of jaw crusher **is **5.71.**

**Calculating the Gape Size when the Capacity of Jaw Crusher, the Width of Crusher and the Closed Single Setting of Jaw Crusher is Given.**

G = ^{CJC x CSS} / _{W}

Where:

G = Gape Size

C_{JC} = Capacity of Jaw Crushers

W = Width of Crusher

CSS = Closed Single Setting of Jaw Crushers

Let’s solve an example;

Find the gape size when the capacity of jaw crushers is 5, the width of crusher is 3 and the closed single setting of jaw crusher is 6.

This implies that;

C_{JC} = Capacity of Jaw Crushers = 5

W = Width of Crusher = 3

CSS = Closed Single Setting of Jaw Crushers = 6

G = ^{CJC x CSS} / _{W}

G = ^{5 x 6} / _{3}

G = ^{30} / _{3}

G = 10

Therefore, the **gape size **is **10.**

**Calculating the Width of Crusher when the Capacity of Jaw Crusher, the Gape Size and the Closed Single Setting of Jaw Crusher is Given.**

W = ^{CJC x CSS} / _{G}

Where:

W = Width of Crusher

C_{JC} = Capacity of Jaw Crushers

G = Gape Size

CSS = Closed Single Setting of Jaw Crushers

Let’s solve an example;

Find the width of crusher when the capacity of jaw crushers is 4, the gape size is 2 and the closed single setting of jaw crusher is 8.

This implies that;

C_{JC} = Capacity of Jaw Crushers = 4

G = Gape Size = 2

CSS = Closed Single Setting of Jaw Crushers = 8

W = ^{CJC x CSS} / _{G}

W = ^{4 x 8} / _{2}

W = ^{32} / _{2}

W = 16

Therefore, the **width of crusher **is **16.**

**Calculating the Closed Single Setting of Jaw Crusher when the Capacity of Jaw Crusher, the Gape Size and the Width of Crusher is Given.**

CSS = ^{G.W} / _{CJC}

Where:

CSS = Closed Single Setting of Jaw Crushers

C_{JC} = Capacity of Jaw Crushers

G = Gape Size

W = Width of Crusher

Let’s solve an example;

Find the closed single setting of jaw crusher when the capacity of jaw crushers is 10, the gape size is 8 and the width of crusher is 5.

This implies that;

C_{JC} = Capacity of Jaw Crushers = 10

G = Gape Size = 8

W = Width of Crusher = 5

CSS = ^{G.W} / _{CJC}

CSS = ^{8.5} / _{10}

CSS = ^{40} / _{10}

CSS = 4

Therefore, the **closed single setting of jaw crusher **is **4.**
