Table Source: Wikipedia (Crushers) Cone crushers use a spinning cone that gyrates in the bowl in an eccentric motion to crush the rock between the cone surface, referred to as the mantle, and the crusher bowl liner.Gyratory crushers are very similar to cone crushers, but have a steeper cone slope and a concave bowl surface. As the gap …

DetailsGrade of concrete is denoted by prefixing M to the desired strength in MPa. For example, for a grade of concrete with 20 MPa strength, it will be denoted by M20, where M stands for Mix. These grade of concrete is converted into various mix proportions. For example, for M20 concrete, mix proportion will be 1:1.5:3 for cement:sand:coarse aggregates.
DetailsThe compressive strength of M20 grade concrete varies between 17 and 23 N/mm2 (i.e. between 170 kg/cm^2 and 230 kg/cm^2) after 28 days curing. This means that the concrete can withstand a compressive load of 170 to 230 kg/cm² before it fails.. In compressive strength test of concrete cube the push force applied on the both faces of concrete …
