# 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:

CJC = G.W / CSS

Where:

CJC = 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

CJC = G.W / CSS
CJC = (10)(8) / 14
CJC = (80) / 14
CJC = 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
CJC = 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;

CJC = 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
CJC = 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;

CJC = 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
CJC = 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;

CJC = 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.
