procedure to estimate the weight and equivalent "d" of rock. The procedure requires measuring the major and minor circumferences or perimeters of the rock in feet. See Figures 1 and 2. The sum of the perimeters can be sued to: 1) graphically read the rock weight in pounds and equivalent "d" in inches from Figure 3; or 2) calculate the rock weight and equivalent "d" by using the ...

Jaw Crusher Working Principle

The crusher is easy to adjust, and, in common with most machines of the jaw type, is a simple crusher to maintain. As rock particles are compressed between the inclined faces of the mantle and concaves there is a tendency for them to slip upward. Slippage occurs in all crushers, even in ideal conditions. Only the particle's weight and the ...

JK Drop Weight Test | JKTech

The JK Drop Weight Test is an industry standard for use in characterising ore under AG/SAG milling conditions. The JK Drop Weight Test provides ore specific comminution parameters which are used in the JKSimMet software to analyse and/or predict crusher and AG/SAG mill performance. This allows for optimisation of current circuits or flowsheet ...

PROCEDURE. The liquid whose surface tension is to be determined was sucked into the capillary tube then it is allowed to fall down due to gravity. 30 drops of liquid were collected in a beaker.The weight of the drops were determined by using electronic balance .The same procedure was repeated 3times to obtain the mean value. By using the value of w 1 & w 2, the surface tension of liquid can be ...

Stalagmometric method - Wikipedia

The stalagmometric method (Ancient Greek: στάλαγμα, romanized: stálagma, lit. 'drop') is one of the most common methods for measuring surface tension.The principle is to measure the weight of drops of a fluid of interest falling from a capillary glass tube, and thereby calculate the surface tension of the fluid.We can determine the weight of the falling drops by counting them.

SAG Mill Comminution (SMC) Test | Mining | SGS

The test procedure requires 100 rocks (minimum 60), or quarter core 'cubes', in any given size fraction of the JK Drop-Weight Test procedure. For the standard size (27-32 mm), this can be obtained by stage-crushing approximately 20 kg to passing 32 mm. Lower weight (5 kg) is often sufficient if the test is performed on smaller rocks.
