A method for predicting the power consumption, product size, and volumetric capacity of jaw crushers based on fracture toughness has been proposed in this study. A new fracture toughness test, the Edge Notched Disk Wedge Splitting test, has been developed and verified in order to rapidly assess the fracture toughness of six quarry rocks.

share of energy consumption for crushing can reach 50% of the annual volume. Part of the electricity is spent on creating a power reserve of the crushing machine (hereinafter—the crusher) due to the fact that, presently, there are no methodologies for computing its electric drive power and determining the energy costs for the rocks destruction.
Another theory is the theory of Kick, ... This paper presents a methodology for the estimation of power consumption in a disc crusher disintegration process. The study covers the dynamic analysis of crush forces acting on the particles and the mobile disc. The forces can be expressed as functions that vary over time.
With a lab-scale jaw crusher as a test case, an optimisation was made on how to operate it most energy-efficiently by using an evolutionary algorithm numerical method.
The main aim of the work was to determine the energy consumption of crushing process assuming a given level of fragmentation. Studies were performed on three rocks: granite "Strzegom", limestone "Morawica" and sandstone "Mucharz".
The power consumption of the equipment and corresponding particle states: (a) the power consumed during the crushing process, (b) the state when the power consumption is the largest (time = 0.1 s), and (c) the state when the power consumption is large (time = 2.0 s), and (d) the state when the power consumption is stable (time = 5.0 s).
Power draw Throughput (2.2) theory Only a fraction of the power consumed by a crusher is actually used for size reduction (Legendre and Zevenhoven, 2014). Most of the energy is lost through noise ...

current power used by the electric engine that drives the jaw crusher at the rate of 20 readings per second. On the diagram of the time-power dependence, energy is represented by the area under the power curve. The energy required for the crushing of individual samples was obtained indirectly, by measuring electrical power. For this
By using the data of E.A. Hersam and F.C. Bond's equation for energy consumption in comminution, a method was developed to analyze the performance of industrial jaw crushers. The study showed that industrial jaw crushers are generally operated below capacity. The study also showed that industrial jaw crushers generally have sufficient installed …
In this work, the specific power consumption of a jaw crusher is predicted with the help of the adaptive neuro-fuzzy interference system (ANFIS) with an accuracy of more than 96% in comparison with the corresponding real data. ... Strength of Materials and Theory of Structures.
In theory, the rock that passes through the rotor does not travel directly toward the rock bed; rather, it hits the bed with an angle. This causes the rock particle to rotate while it hits rocks along the bed. ... The work in this article has focused on a way to model the capacity and power consumption in a VSI crusher. The simulations of power ...
To clarify the results of determining the crushing force in a roller crusher, it is recommended [2, 3] to use the loosening coefficient of the material, which constitutes 0.2–0.3 for strong rocks, 0.4–0.6 for clay, but it has quite a wide range of values and does not allow calculating the required value of the drive power of roller crushers ...
The importance of crushers in the mining industry declined with the introduction and resultant dominance of AG and SAG based circuits, but the recent move to consider more energy efficient ...
theory of the disintegration process [5]. For that reason, it is important to obtain the power consumption, which is related to energy consumption in a time interval. Consequently, the estimation of the required power for disc crushers is essential in a fragmentation process. Although there are theories that give an approximation of
The authors state that the models they obtained are useful for predicting key indicators such as power consumption, product size, capacity, and equipment wear and tear. The MDE also simulates the effect of changing …
A twin-roll crusher is selected, like those given in the Roll Crusher capacity Table above, to serve as the reduction crusher. The smallest, 24 x 16 roll crusher shown in the Roll Crusher capacity Table above has enough capacity with a setting of 1 in. but the maximum size feed will be too large, that is, the stage of reduction is not large enough.

The procedure works quite well for this type of crusher but tends to understate power requirements in fine crushers where power rates are typically much higher (upwards from 0.25 KWH/tonne). Because of this, a research program was instituted by Allis-Chalmers Comminution Task Force Committee to break rock in a manner more analogous to that ...

Korman et al. (Korman et al., 2015) measured power consumption of jaw crusher during crushing of rocks such as dolomite, limestone, spilite and diabase rocks and obtained similar trends, i.e higher the strength of the rock, higher the crushing energy. It is worthy to note that the crushing concrete specimens with 40 MPa took more time than ...

The cone crusher is a modified gyratory crusher, and accordingly many of the same terms including gape, set, and throw, apply. The essential difference is that the shorter spindle of the cone crusher is not suspended, as in the gyratory, but is supported in a curved, universal bearing below the gyratory head or cone (Figure 6.8).Major suppliers of cone crushers include …
The essential problem within these theories is their limited range of applicability as they were based on empirical equations fitted from experimental data applied in certain cases. Eloranta [4] used Bond's theory to estimate the crusher power consumption and recorded 240% higher predicted power than the actual value.
