Inin-pit crushing, theprimary functionof acrusheris to provide a smaller uniform product size for each of transport by the conveying system. Minimum power consumption in part of a good design. For their coarse duty,primary crushersuse, comparativelylower energy, to other systems. Thehorsepower requiredvaries with the size of product being made, the capacity and the toughness of the rock or ore.

Reducing the speed of thecrusherresults in increasedenergyconsumption per tonne ofcrushedmaterial. The increase is about 0.25 kWh/t, independent of F 10. The lowestenergy consumptionper tonne is found with highcrusher speed, high CSS and low F 10 size.

The feed comes from theprimary crusherand will have a certain amount of rock that doesn’t need furthercrushing. To run this ore through thecrusherwill be a waste ofenergy and crushingspace. Ideally it should be removed. Toremoveitrequiresa procedure called “SCALPING”.

A primary gyratory crusher was required to crush iron ore at the rate of3000 t/h. The largest size of the run-of-mine ore was 1000 mm. The required product size was less than 162 mm. Manufacturer’s data indicated that the nearest size of gyratory crusher would be1370 mm × 1880 mm…

Metso's Superior™MKIII primary gyratory crushershave new advancements that bring increased speeds, higher installed power and mechanical improvements. All of these combine to bring up to a 30% additonal throughput for yourprimary gyratory crusher.

Dec 10, 2018· One way to saveenergyis by blasting more and crushing/grinding less. This way you can reduce the feed size beforeprimarycrushing, increasing circuit throughput and reducing theenergy requiredfor downstream comminution. Blasting is the most cost-efficient means for ore size reduction. Chemicalenergyis cheap as opposed to electricalenergy.

Sep 02, 2019· Today,primarycrushing is viewed as more important within the balance of production and proper sizing needs. The size and type of theprimary crushershould be coordinated with the type of stone, drilling and blasting patterns, and the size of the loading machine. Most operations will use a gyratory, jaw or impactcrusherforprimarycrushing.

A jawcrusher’s flywheel, toggle plates, pitman, eccentric shaft, and driving motor generate the crushing action and provide theenergy neededto break the material. There are some different styles of JawCrushers, the most common being the overhead eccentric jaw (shown above) or a double toggle jaw.

Apr 03, 2015· Types ofcrushers.Crushersare classified into three types based upon the stage of crushing they accomplish. These are (i)primary crusher, (ii) secondarycrusher, and (iii) tertiarycrusher. Theprimary crusherreceives material directly from run of mine (ROM) after blasting and produces the first reduction in size.
