\u00a0— How to choose a proper rock crusher<\/strong><\/p>\n

\"stone<\/a>No matter how you process your gold, silver, or copper ore, crushing is the first step.\u00a0 It takes the rock from whatever size it was when it left the mine and processes it to a size that allows any valuable minerals to be extracted.\u00a0 Problems in the crushing process can dramatically reduce recovery rates and even cause damage to equipment downstream in the processing cycle.\u00a0 Just as important, poor crushing can dramatically increase the cash cost of your final product.
\nThe two best known crusher types are the jaw crusher and the cone crusher.\u00a0 The jaw crusher, or toggle crusher works on a cam mechanism where the material is progressively crushed smaller and smaller as it travels into the crusher and out the bottom.\u00a0 Since not all the crushing is done in one stroke, the movement of the jaw can be quite small.
\nThe second major type of crusher is the cone crusher or gyratory crusher.\u00a0 It has two cones that crush the material.\u00a0 There are also impact crushers, which were popular in the Western mining days, and roller crushers.
\nAlthough every crusher has its own strengths and weaknesses, there are several factors that experts ask you to consider before picking the crusher for your operations.\u00a0 These will help determine the best design for you.<\/p>\n

IS THE CRUSHER HEFTY ENOUGH FOR YOUR NEEDS?<\/strong>\u00a0 Crushing is a brute force operation and the power input and vibration can wreck a poorly made machine.\u00a0 Cheaper machines can \u201cskimp\u201d on the metal that is necessary to withstand the vibration and eventually stress cracks will form.\u00a0 The same holds with repairs.\u00a0 A good crusher repair facility will charge more, but make sure the repairs will stand up to stress according to P.R. Engineering.<\/p>\n

HOW GOOD IS YOUR BLASTING CREW?<\/strong>\u00a0 Miners say that it is easier to break up ore in the ground than in a crusher.\u00a0 That\u2019s why blasting can be critical.\u00a0 A well prepared shot can even eliminate one crushing process, which will lower crusher costs and improve processing speed.\u00a0 You may find an investment in blasting software and the right blasting agent will be cheaper than a bigger crusher.<\/p>\n

CAN THE CRUSHER HANDLE THE MAXIMUM CAPACITY WITHOUT UNDUE STRAIN?<\/strong>\u00a0 Don\u2019t think you can overload your crusher without paying a penalty.\u00a0 If you are overloading your crusher, you are dramatically increasing your maintenance costs and shortening the life of the machine.\u00a0 If you foresee times when you will have to push more material through your crushing process, you should either buy a bigger machine, or invest in an additional crusher that can handle the extra material.\u00a0 This machine can either be a used crusher or one of the cheaper ones.<\/p>\n

CAN THE MACHINE HANDLE THE LARGEST POSSIBLE LUMP SIZE?<\/strong>\u00a0 One oversized piece of rock can wreck a crusher.\u00a0 In that case, you might want to buy a better machine that can handle oversized material or invest in your blasting team so you get better uniformity in the shot process.<\/p>\n

WILL THE MACHINE PRODUCE TOO MANY FINES.<\/strong>\u00a0 Obviously, you don\u2019t want fines if your process doesn\u2019t call for them.\u00a0 But, even if you need to produce a fine powder, you don\u2019t want it to come out of your crusher.\u00a0 These fines will add to your dust control problem and may require additional dust control equipment, which will cost more money and require additional engineering.\u00a0 Fines also have a way of gumming up or abrading equipment, which will add to maintenance costs.\u00a0 And, don\u2019t forget that airborne dust means health issues.<\/p>\n

HOW MUCH NOISE AND VIBRATION WILL THE CRUSHER PRODUCE?<\/strong>\u00a0 Vibration means the crusher is undergoing stress, which can lead to increased maintenance and reduced life.\u00a0 The noise means safety issues like ear protection.\u00a0 It also contributes to accidents because constant noise contributes to worker fatigue.<\/p>\n

HOW DOES YOUR CRUSHER HANDLE YOUR SPECIFIC MATERIAL?\u00a0<\/strong> This is important but often forgotten in the search for a good deal.\u00a0 Tough, abrasive, corrosive or sticky material all has different requirements and problems.\u00a0 A crusher designed for one material maybe totally wrong for another.<\/p>\n

IS THE MACHINE SUITABLE FOR YOUR WORKING CONDITIONS?<\/strong>\u00a0 Mining conditions in the US range from below zero to over 100 degrees and from bone dry to humid.\u00a0 In fact, material can act different in varying conditions, which means that the wrong crusher can provide different results in different conditions.<\/p>\n
