1. An important parameter of the jaw crusher is the maximum feeding size. Generally, the maximum material size of the jaw crusher is greater than or less than 75%, so the maximum size of the feed material should not be greater than 0.85 times the width of the feed port, otherwise it will reduce the output of the machine or damage the crushing …

The closed side setting can be calculated by deducting the stroke from the OSS. CSS is the most important crusher parameter since it defines the maximum product size and has significant bearing on capacity, product gradation, power draw, and wear. The nip angle is the angle between the fixed and movable jaw dies.

Figure 1. Kinematical scheme and kinematic parameters of single-toggle jaw crusher 3. Capacity determination methods To date, many theoretical, empirical and semi-empirical dependencies for approximate evaluation of a single-toggle jaw crusher capacity have been proposed. The generalization of these dependencies is proposed in [17].

Best suited for secondary crushing applications, cone crushers are designed to crush pre-sized materials, usually 100mm, 150mm or 200mm, depending on the size of the crusher. Cone crushers can form finished products down to 12mm or less. Like the jaw crusher, the cone crusher provides a relatively low cost crushing solution, but there are ...

In this study, the effects of three different choke feed level (1/1, 1/2, and 1/4) and four different effective reduction ratios (2.5, 5, 10, and 20) depend on the capacity of the crusher of the three different characteristic coal samples in a laboratory Jaw crusher were investigated. Instead of the one-stage reduction, the capacity of the jaw crusher with a …

Hence, research aimed at the mathematical modeling and optimization of the parameters of jaw, cone, hammer, two-roll and single-roll crushers is, currently, being widely conducted. On the other hand, similar studies of promising single-roll gyratory crushers for crushing strong rocks in mines have not, yet, been performed.

This dependance of energy consumption on aperture size is largely important. If the energy consumption of a jaw crusher needs optimization then aperture size is the parameter to be under further investigation because the modification of aperture size on the jaw crusher leads to reduction of energy consumption.
