experienced by the crusher jaw during service The purpose of this paper is to select a suitable candidate material for the design of crusher jaw that can sustain fracture by any of the three modes of failure tear shear and impact at low cost using CES EduPack Keywords Crusher jaw Material selection CES EduPack Fracture Comminution 1
Factors affecting the working efficiency of Jaw Crusher 1 Material hardness The harder the material is the harder it is to crush and the more serious the wear and tear of the equipment Long term use of high hardness materials jaw crusher crushing speed is slow poor crushing capacity affecting work efficiency
Korman et al Korman et al 2015 applied direct measurement of the power on the jaw crusher motor to evaluate the effect of mechanical properties of rocks on crushing energy of jaw crusher
of stone by hydraulic hammer and crushing in a jaw crusher the stone samples were selected from various rocks in five different quarries «Kremešnica» near Lasinja «Vukov
1 Bearing Damage Reason Incomplete lubrication and untimely maintenance of bearings lead to poor lubrication;; The impact of moving jaw caused by excessive feeding height is also the key factor of bearing damage Solution Timely carry out lubrication and maintenance according to the maintenance manual use the specified lubricating grease and fill the grease in time according
Besides being an important item for the machine s performance the jaw crusher s jaws are responsible for front frame and swing jaw protection Wear generally causes loss in production due to increased crushing angle loss of tooth profile reduction of the CSS to compensate the possible lamellar effect etc
The modeling of the jaw crusher using mathematical expressions has also been studied by a number of researchers For example in where K N = n σ 2 120 γ E σ —the material hardness e —the efficiency coefficient The structural model of the cone crusher is shown in Figure 2
for the effect of feed size on jaw crusher capacity Capacity th I Size of Rose and feed m Hersam W English WR WaIWR Characteristics such as hardness and surface friction de termine the ease with which a particle is nipped andcrushed Table 2 Effect of throw on jaw crusher capacity from Hersam
In the process of operation jaw plate is often worn which affects the normal performance of jaw crusher This paper studies the low carbon alloy steel material of jaw crusher and discusses the change law of jaw plate hardness and wear resistance so as to determine the quenching temperature when jaw plate wear resistance reaches a good level
Integrative installation of motor chassis and crusher frame not only saves installation space of jaw crusher but also reduces the length of Vee belt Thanks to synchronous movement of crusher frame motor chassis and motor The crusher capacities listed are based on instantaneous sampling of medium hardness rocks The above data is for
for erection Swing jaw with bearings 28 t Heaviest piece for maintenance Jaw liner 4 5 t Main dimensions of the crusher L x W x H Approx 4 500 mm x 3 300 mm x 4 000 mm 1 The actual throughput depends on the feed material characteristics bulk density hardness UCS feed particle size distribution moisture content the desired
The output product of a jaw crusher was studied by Olaleye [7] and Mu [8] in terms of how it varies with ore 40 body strength as well as using Discrete Element Modelling DEM techniques
Download scientific diagram Specific energy of crushing of various rock types from publication Impact of rock hardness on fragmentation by hydraulic hammerand crushing in jaw crusher The
Jaw crushers are a type of crushing equipment widely used in industries such as mining and construction They are mainly used to crush large pieces of انتقل إلى المحتوى
Hardness of the rock is typically measured using the Mohs scale where talc is rated as 1 softest and diamond as 10 hardest This scale helps determine what type of rock crusher is needed for the job The exception though is that small/mini jaw crusher while perfect for concrete block and brick should not be used for hard rock
hardness Available in four sizes as a light or heavy duty model they achieve throughputs of 250 t/h to 1 400 t/h The single toggle jaw crusher with the largest antifriction bearings and highest flywheel energy 1 with new crushing elements 2 1 200 possible
Jaw crusher; Hammer crusher; 1 Gyratory crusher Gyratory crushers are designed for medium to high hardness rocks ores and corrosive materials If your materials have low hardness a hammer crusher is a great choice However for large and hard materials jaw crushers and gyratory crushers are more suitable
Austenitic manganese steel with 18% Mn and % Cr presented high abrasive wear resistance with a wear rate 18% lower than that of the alloy used in the manufacture of cone crusher linings Higher hardness values result in a lower wear rate and the use of austenitic manganese steel with 18% Mn and % Cr represents an opportunity to increase
Jaw Crusher Gouging Abrasion Test1 This standard is issued under the fixed designation G81; the number immediately following the designation indicates the year of original material of suitable hardness is run through the crusher The minimum opening is then reset to mm in and another 225 kg 500 lb of rock is crushed This is
