·Most of the costs in open pit quarry operations occur in crushing and grinding processes Therefore the management of crushing grinding processes is very important Many researchers investigated the effects of pile size distribution and specific charge values occurring as a result of blasting on crusher energy consumptions and provided some cost reductions in
·of energy consumption and to analyze dominant parameters that affect this energy consumption The develop ment of a gyratory crusher model was achieved in the following three main stages
·The specific energy consumption when crushing at the maximum available power can also be calculated by dividing the crusher motor s nominal rated power with the crusher s capacity at various CSS s By combining these two methods we can identify the CSS where the same specific energy consumption is calculated by the two different methods
·The practical method of operation of each type of gyratory crusher is indicated and the various methods of computing operating variables such as speed of gyration capacities and power consumption given are prescribed by different authors The methods of calculations are illustrated to obtain optimum operating conditions of different variables
·The vertical shaft impact VSI crusher is a commonly used machine in aggregate production A comprehensive understanding of the physical phenomena that influence the power consumption and the particle output of the device are essential to enable development of protocols that minimize energy consumption during rock crushing
·The study revealed that feed gradation crusher settings and crusher speed affect specific energy consumption during the crushing process while particle shape is influenced by all parameters As to double toothed roller crusher Li et al 2019 established a discrete element method DEM model of the crushing process of a toothed double roll
This paper provides an energy consumption model and explains how the operating conditions and structural parameters of a crushing chamber affect energy consumption Energy consumption is closely related to compressive pressure and displacement The relationship between pressure displacement and structural parameters is discussed The influence of operating parameters
operational costs power consumption vibration noise and environmental issues [4] More so crushers can be classified on the basis of the breaking forces as a impact crushers hammers and rotor impactors [4 5]; Figure 3 illustrates the angle of nip in a jaw crusher Figure 3 Angle of nip in a jaw crusher Crusher Jaw Plates
·The plate warping reduces the crusher performance resulting in low crusher efficiency high cost of replacing the crushing plates and higher energy consumption
The impact of different aperture size 5 mm and 25 mm on the energy consumption was also studied From the experimental results it is demonstrated that there is a strong dependance of energy consumption on the compressive strength of concrete
·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 • Feed the above sample of coal to a jaw crusher and crush it Measure the time for crushing
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

·A material is crushed in a jaw crusher and the average size of the particle reduced from 5 cm to 1 cm with the consumption of energy of times 10^4 J/kg What will be the consumption of energy in kJ/kg to crush the same material of an average size of cm to cm assuming a Rittinger s law {#1} b Kick s law {#2}
·A material is crushed in a Blake jaw crusher such that the average size of particle is reduced from 50 to 10 mm with the consumption of energy of kW/ kg/s What would be the consumption of energy needed to crush the same material of an average size of 75 mm to an average size of 25 mm a
The width of the hopper was times the gape The ore contained 20% material minus cm The bulk density of the rock was t/m3 and the nip angle ° Determine 1 capacity of crusher 2 power consumption if the work index of the material is kWh/t 3 operating speed
The nip angle is affected by the distance between the rolls The nip angle is defined as the angle that is tangent to the roll surface at the points of contact between the rolls and the particle It depends on the surface characteristics of the rolls Usually the nip angle is between 20° and 30° but in some large roll crushers it is up to 40°
·In the short term this would annually equal worldwide savings of 31 100 million euros 280 TWh energy consumption and a CO 2 emission reduction of 145 million tonnes In the long term the annual benefit would be 62 200 million euros 550 TWh less energy consumption and a CO 2 emission reduction of 290 million tonnes
·In contrast to smooth rolls these offer improved nip conditions so that larger particles can be nipped and crushed Furthermore toothed rolls produce less fine material which can be advantageous for certain downstream processes and reduce the mass specific energy consumption at this stage The roll crusher has two cylindrical rolls
·The design has been developed for a single roll crusher with the forced supply of destroyed material into the crushing zone [] The capture of a crushed piece occurs due to the stop located on the roll see Fig 1 ; in this case the condition for formation of a complex stress state in the crushed piece is observed and the energy consumption is reduced by 39 40% []
·The crushability grindability and cutability of rocks are associated with many factors During the size reduction processes in a jaw crusher and rod mill crushing and grinding energy consumption increase when finer size fractions of the product are desired Zeng and Forssberg 1992 Heikkilä Heikkila 1991 reported that the lithological features affect the
