Compression and impact forces are extensively used in crushing operations while attrition is the dominant force in grinding The primarily used equipment in crushing are jaw crushers gyratory crushers and cone crushers whereas rod mills and ball mills usually closed circuited with a classifier unit are generally employed for grinding purposes in a mineral processing plant
Moisture content will have a marked influence As 1000kg of pure water = 1 cubic metre those materials under 1000kg/cu m will float more dense will sink ie those materials with a specific gravity more than 1
05 05 2011 If the 3/4 crushed stone has sufficient fines in it a proctor curve can be obtained We see it used extensively on projects Ron is correct that nuclear density testing on clean rock is inaccurate at best The choice between backscatter and direct transmission can be governed by the layer thickness

26 12 2015 Impact crushers are commonly used to crush rocks with a silica contain under 5 such as coal limestone and phosphate The only reason why you would use an impact mill/crusher or a hammer mill on a high silica rock is because it might be sticky in nature and rich in clay
rock factor that depends on rock density rock strength and jointing A = 0 06 RMD RDI HF 3 6 The rock characterization factor A is calculated to correct the mean fragment size It is made up of 3 factors which are the rock mass description RMD rock density influence RDI and the hardness factor HF 2 2 3 9
The effect of grading and density on the mechanical properties of a crushed dolomitic limestone This paper describes laboratory tests on specimens of dry crushed dolomitic limestone of different gradings carried out in order to determine the characteristics necessary for use in pavement design and evaluation computations involving analytical methods
consumption for crushing was compressive strength Fracture toughness and tensile strength of the rocks had a significant impact on the crushing energy The effect of bulk density was not large while for the hardness could not be stated that it had influence By the analysis of deviations of specific crushing

12 01 2015 Since the mass and volume both do not change when re shaping the clay the density does not change Even though it may seem as if the clay is more compressed tightly packed in the oval than in the hollow square the spacing between those tiny particles that make up the clay is constant does not change Therefore the shape of a material/substance does not affect its density
