Scope of laboratory tests within Metso
Full scale testing of Metso's HP cone.
Brief description of some major tests:
The abrasion index
gives an indication of the abrasiveness of the material and is used for estimating the service life of wear parts for crushers.
gives an indication of the abrasiveness of the rock material.
Bond work indices (or “impact work index”)
can be used for estimating the crushability of material and the crusher's energy consumption.
The crushability value
can be used for estimating the degree of difficulty of the material tested.
The dynamic fragmentation value
gives an indication of the material's resistance to impact.
The flakiness index
gives the percentage of flaky particles in the sample.
The Los Angeles value
gives an indication of the resistance of the material to abrasion and impact.
The sand flow test
is for estimating the shape of fine aggregates (< 2 mm).
A sieving analysis
is performed to determine the particle size distribution of the sample.
is the mass (g) per unit volume of the material (mm3).
