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.

The springs are helical and pressure varies with the size of crusher and could be as high as 6 t/m (about 8300 kPa). In some roll crushers the rolls are individually driven. ...

The F. Bond Pendulum crusher . Carring on with a theme that we've already touched in the previous publication, we will consider the methodology of the F. Bond index calculating.As you know, there are three calculation methods. The method selection depends on the crushing/grinding stage (the power size and the necessary finished class).

This method of power calculation can be used for calculating the approximate power of primary jaw and gyratory crushers, secondary gyratory crushers, and cone crushers. For empirical values of work index for different materials, see Table 25.3.2.4. An example of the use of the formula follows. Example 25.3.1.1. Assume a copper ore with Bond crusher

calculation procedure for the crushing power of crushers is proposed where the torque is computed with radial forces because only these forces are transmitted to the eccentric. 2. Gyratory Crusher A gyratory crusher consists of a movable and truncated conical head and a fixed concave shell, as is presented in Figure1.

You can calculate power required by the bonds law of crushing. For more about the bonds law, see the link below

Creating a parametric model of the hull of the fixed crusher jaw. 2 Development of the algorithm for optimizing the body of the fixed jaw To determine the safety margin of the jaw body, we will perform a preliminary calculation of the stress-strain state. We use the finite element method implemented in the complex of

Additionally, jaw crusher feed should be pre-screened using a grizzly screen prior to crushing to remove material finer than the closed-side setting. Setting jaw crushers. Ideally, the reduction ratio of a jaw crusher should be 6-to-1. There are different ways to calculate reduction ratio, but the best way is something called the P80 factor.

The power requirement of the crusher depends upon the size and capacity. One of the laws of comminution or crushing has been proposed by Rittinger. According to Rittinger's law, the work required for size reduction is …

Fresh feed rate and crusher feeding condition (choke-fed/trickle-fed) had significant impacts on size reduction of manual control. Only automatic control compensated for the effect of feed rate and crusher feeding condition. •. CSS showed a decreasing trend to compensate for wear (both automatic and manual control) •.

The crusher size is typically specified by the inlet dimensions, such as 18 by 18 in., or 3 by 4 ft. Shaft seals are used where the shaft penetrates the housing to prevent fine materials from leaking out of the housing. The bearings are usually located outboard from the housing and seals to keep material from wearing on the bearing seals.
