Rock Crushing Theory and Formula using Kick & Rittinger's Law

Rittinger’s theory and law of the energy expended in crushing of rock is that the work of crushing is proportional to the reduction in diameter; or, as I have more fully expressed it: “The work done in crushing is proportional to the surface exposed by the operation; or, better expressed for this purpose, the work done on a given mass of rock

Theoretical analysis and experimental research on the

Jul 01, 2016 The energy consumption model of rock crushing is developed based on fractal and fracture mechanics theory. • A quantitative relationship between the energy consumption and average size of rock fragments are obtained. • A calculation method for determining the rock fracture surface energy is introduced according to the SHPB tests. •

Rock breakage by crushing, blasting, and drilling

Geol., 2 (5) (1968) 293-314 ROCK BREAKAGE BY CRUSHING, BLASTING, AND DRILLING 303 E = kzLz -/kaL3 4- k4L4 (22) where k2, k3, and k4 are constants and L is a linear dimension related to the crater geometry. In the above equation the first term is related to the surface area of the broken rock and corresponds to the prediction of Rittinger's law

Impact Crusher Working Principle

Apr 19, 2018 The rock samples selected for crushing in this device are usually minus 38mm (1-½”), plus 19mm (¾”) in size. The sample rock is weighed and then placed between the platens. The end of the rebound platen is placed in contact with the rebound pendulum and the crushing pendulum is raised to a predetermined vertical height which depends on

Ilmenite Wikipedia

Ilmenite, also known as manaccanite, is a titanium-iron oxide mineral with the idealized formula FeTiO 3.It is a weakly magnetic black or steel-gray solid. From a commercial perspective, ilmenite is the most important ore of titanium. Ilmenite is the main source of titanium dioxide, which is used in paints, printing inks, fabrics, plastics, paper, sunscreen, food and cosmetics.

Distribution and properties of placer ilmenite in East

The Ilmenite forms the major mineral in the beach sands nearly north of Rosetta (Fig. 1 and 2). The principal richness of Ilmenite is contained in the area "B" which is close to Abu-Khashaba. The average value of Ilmenite all over the beach comes to 8. 128%. The mineral is found in normal distribution (Fig. 3) and this confirmed the deposition

Ti-bearing minerals in sedimentary kaolin deposits of Egypt

Nov 01, 2014 Occurrence of both ilmenite and leucoxene in the sand fraction of the sedimentary kaolin deposits from Egypt is consistent with the alteration of ilmenite to leucoxene during diagenesis. Ti released by this alteration, subsequently recrystallized as anatase.

Utilization of Egyptian Ilmenite Ore for Steel Surface

So it was important to search for sand substitution among the local abundant minerals in Egypt. Waste product obtained from ilmenite ore extracted from the mine was found to be the most suitable alternative abrasive. This work shows the abrasive types, the occurrence of the ilmenite ore.
