d1 and d2 are parameters that are characteristic of the crusher. They are determined primarily by the setting of the crusher. Data from operating crusher machines indicate that both d1 and d2 are proportional to the closed side setting. d1 is the smallest size particle that can be retained in the crushing zone during the opening phase of the cycle.

Cost. With the design differences also comes cost differences. The Double Roll Crusher is the more cost-effective option of the two. The main differences that make up the majority of the cost differences is the drive configurations. Since the Double Roll Crusher is V-belt driven, lower motor horsepower can be used due to the flywheel design.

It is stated as a percentage of the new feed to the crusher. The equation for circulating load percentage is: R = 100/E/r-1 where R = circulating load, % E = screen efficiency, % r = % oversize in crusher product. To help understand this determination and the equation use, take the example of 200 tph original or new material to the crusher.

Let's consider the spring constant to be -40 N/m. Then the applied force is 28N for a 0.7 m displacement. The formula to calculate the applied force in Hooke's law is: F = -kΔx. where: F is the spring force (in N); k is the spring constant (in N/m); and Δx is the displacement (positive for elongation and negative for compression, in m).
