The image above represents jaw crusher rating. To calculate jaw crusher rating, two essential parameters are needed and these parameters are Gape Size (G) and Width of Crusher (W).
The formula for calculating the jaw crusher rating:
Jr = GW
Where:
Jr = Jaw Crusher Rating
G = Gape Size
W = Width of Crusher
Let’s solve an example;
Find the jaw crusher rating when the gape size is 15 and the width of crusher is 5.
This implies that;
G = Gape Size = 15
W = Width of Crusher = 5
Jr = GW
That is, Jr = (15)(5)
Jr = 75
Therefore, the jaw crusher rating is 75.
Calculating the Gape Size when the Jaw Crusher Rating and the Width of Crusher are Given
G = Jr / W
Where:
G = Gape Size
Jr = Jaw Crusher Rating
W = Width of Crusher
Let’s solve an example;
Find the gape size when the jaw crusher rating is 32 and the width of crusher is 2.
This implies that;

Jr = Jaw Crusher Rating = 32
W = Width of Crusher = 2
G = Jr / W
That is, G = 32 / 2
G = 16
Therefore, the gape size is 16.

Calculating the Width of Crusher when the Jaw Crusher Rating and the Gape Size are Given
W = Jr / G
Where:
W = Width of Crusher
Jr = Jaw Crusher Rating
G = Gape Size
Let’s solve an example;
Find the width of crusher when the jaw crusher rating is 40 and the gape size is 4.
This implies that;
Jr = Jaw Crusher Rating = 40
G = Gape Size = 4
W = Jr / G
So, W = 40 / 4
W = 10
Therefore, the width of crusher is 10.
