Both hammers of the "pendulum" will impact the smallest measured side on the rock. The hammers are set to fall again from a higher drop position to input enough energy to break the rock. This is done 10 times to obtain 10 breaks and the WI (kWh/t) = 53.49 x Impact Crushing Strength / Specific Gravity of the sample. ** jktech.com.au

The low specific gravity of basaltic crusher dust, 2.59 as compared to cement, i.e., 3.14, resulted in a reduction of the density of the blended hollow concrete block. 4 Conclusion. Despite the basaltic crusher dust satisfying the pozzolanic chemical requirements, it is coarser than the Portland Pozzolana Cement. This means the basaltic …

About Stone, crushed. 1 cubic meter of Stone, crushed weighs 1 602 kilograms [kg] 1 cubic foot of Stone, crushed weighs 100.00959 pounds [lbs] Stone, crushed weighs 1.602 gram per cubic centimeter or 1 602 kilogram per cubic meter, i.e. density of stone, crushed is equal to 1 602 kg/m³.

An impact crusher uses mass and velocity to break down feed material. First, the feed material is reduced as it enters the crusher and makes contact with the rotating blow bars or hammers in the rotor. Secondary breakage then occurs as the material is accelerated into the stationary aprons or breaker plates.

4. There is a great effect on specific gravity of soils on mixing stone dust with them. Adding 30% stone dust is found to be optimum in case of specific gravity. References [1].

Multiply the product from step (9) by the tons per hour to obtain the gross hp required. Cone Crusher Motor Sizing. Hard limestone, having an impact strength of 15, is fed from a secondary crusher set at 3¼-in. open side setting, producing stone having 80 percent minus 3¼-in. The product of the secondary crusher is screened at 5/8-in.

The specific gravity of the sample varied between 2.6–2.8 at different locations. This is attributed to the time of deposition of sediments in the flood channel being well over 80 years. Since the selected dredged soil consists of 94% silt, liquid limit tests were also performed using cone penetration method for cross-validation.

The relative density (specific gravity) of an aggregate is the ratio of its mass to the mass of an equal volume of water. Relative Density = Mass of the Aggregate / Mass of equal volume of water. Key Features: Most aggregates have a relative density between 2.4-2.9 with a corresponding particle (mass) density of 2400-2900 kg/m3 (150-181 lb/ft3).

There are two main types of impact reduction, gravity and dynamic. Attrition: Rubbing the material between two solid surfaces.
