It is especially suitable for places with limited space, such as underground, tunnel, etc. Hydraulic Jaw Crusher. It is a compound pendulum jaw crusher, using a hydraulic cylinder as safety …
The work index includes the friction in the crusher and the power given by above eq is gross power PROCEDURE: • Start the jaw crusher and find the power consumption under no load condition with the help of energy meter and a stop watch. • Prepare the sample you want to crush in the jaw crusher.
The plate warping reduces the crusher performance, resulting in low crusher efficiency, high cost of replacing the crushing plates, and higher energy consumption. Moreover, the wear of the jaw liner profile lowers the crusher performance by affecting the shape and the overall size of the crushed particles [ 12, 13 ].
Korman et al. [25] stated that the uniaxial compressive strength (UCS) of rocks is a dominating factor for crushing energy consumption in jaw crushers. Kahraman et al. [26] and Comakli and Cayirli ...
Abstract. This paper presents the measurement and analysis of energy consumption of a laboratory jaw crusher during concrete recycling. A method was developed to estimate …
In other words, jaw crushers tend to leave higher levels of cement paste adhered to recycled aggregates, ... Abrasion crushers generate high quality RCA with an energy consumption which is lower [15] than that of methods involving heating and rubbing [3]. Abrasion is reported to remove most of the attached cement paste, resulting in an …
Due to the inefficiency of the jaw crushing machine, whose no-load power consumption is between 40 and 50% of its rated power, the optimal switching control …
The original Blake crusher was designed with a vertical stationary jaw. Probably the first departure from this arrangement was an 84 X 66″ crusher, built in 1914. This machine conventional design, in that the swing jaw was made vertical. Later, when the Superior line was developed, a compromise between these two extremes was used in ...
Energy consumption values of the crushers were calculated with obtained ampere values by using first equation given above for each blast test and energy consumption values of the crushers per tonne were also determined by dividing these values by material amount supplied to the crushers per hour (Table 6). Reduction ratio …
Jaw crushers are robust, being an attractive option in operations where the feed has a coarse top size and a moderate reduction ratio without fines is required . Their performance, in terms of capacity or …
Energy consumption Practice shows that the energy consumption of the medium size gyratory crusher is much less than the same size jaw crushers. The enemy consumption of jaw crusher is high mainly because it adopts the discontinuous impact crushing, and need to work in with several types of equipment.
This paper presents the measurement and analysis of energy consumption of a laboratory jaw crusher during concrete recycling. A method was developed to estimate the power requirements of a lab-scale jaw crusher. The impact of material properties on the crusher performance is studied. Eight concrete strength classes (C20/25–C80/95) were ...
The energy consumption using the laboratory vibratory jaw crusher is estimated by Mazur [82] for limestone and diabase. In this study, electrical energy is measured as a function of changing ...
analysis of the results shows that taking into account energy consumption, it is better to use two-stage crushing process. For given materials energy consumption in the two-stage crushing process was reduced by 30%. Key words: rock crushing, jaw crusher, crushing efficiency, two stage crushing process 1. INTRODUCTION
There has recently been a notable concern about energy consumption in reducing the size of stones that has led to considerations of reducing the weight in the jaw crusher, specifically the blow plate so that it can withstand the strength of the stone placed in the crusher . The mathematical modeling for the crushing variables and performance ...
of Energy Consumption of a Single-T oggle Jaw Crusher. In Proceedings of the Sustainable Research and In Proceedings of the Sustainable Research and Innovation Conference, Juja, Kenya, 2–4 May ...
Previously, jaw crushers were modelled in regard to certain aspects, for example, energy consumption (Legendre and Zevenhoven, 2014) or kinematics (Oduori et al., 2015). Approaches to date have ...
Jaw crusher is used as primary crusher, it's reduction ratio is usually 6:1. It uses compressive force to break the material, this mechanical pressure is achieved by the two jaws of the crusher. It is called a jaw crusher because it works the same was a human jaw does-food goes into your mouth and your bottom jaw pushes the food up against ...

Reducing the speed of the crusher results in increased energy consumption per tonne of crushed material. The increase is about 0.25 kWh/t, independent of F 10. The lowest energy consumption per tonne is found with high crusher speed, high CSS and low …
The simulation results show that due to the high no-load power consumption of the jaw crusher, the optimal switching control of the jaw crushing process can achieve considerable energy saving and cost saving as compared to the variable load-based optimal control. However, switching the jaw crusher will result in severe impact in practice.
