15/05/2014& 0183;& 32;If the crushing force is not sufficient no crushing occurs.The material may deform. THAT IS THE REASON TO USE RUGGED MASSIVE CRUSHERS IN MINERAL DRESSING. 26. 28 The best method to cause rapture in solid materials is the appli ion of shearing loads. The orientation of crystals in ores is generally irregular. So compressive force is sufficient.
24/12/2008& 0183;& 32;Reduction in size is accomplished by five principal methods: 1 crushing a slow appli ion of a large force; 2 impact a rapid hard blow as by a hammer; 3 attrition a rubbing or abrasion; 4 sudden release of internal pressure; and 5 ultrasonic forces. The last two methods are not in common use.
Similar laboratory breakage tests are being developed with the objective of specifying breakage parameters for autogenous and semi-autogenous mill models.
