Uniaxial Compressive Strength - an overview

Uniaxial compressive strength (UCS) is a key physical test relevant to iron ore crusher design and rock geomechanics for mining. Tests are typically performed on intact lengths of NQ, HQ, or PQ diamond drill core and record the maximum axial load sustained at the point of failure.

Comparison of UCS to Bond Work Indices

UNCONFINED COMPRESSIVE STRENGTH (highlighting three rock types) Figure 4 displays Wi C and UCS values separated by the major rock types from a single African mine. The three rock types do show a mild correlation between crushing Work Index and UCS (R² values between 0.1 and 0.4).

v116n3a5 Rock Strength and Geometallurgical Modelling

UCS is used widely in the mining industry to quantify rock strength. An investigation using point load index (PLI) data converted to UCS has revealed a direct relationship between grain size and UCS at Mogalakwena. This correlation is best seen in Rock Strength and Geometallurgical Modelling, Mogalakwena Mine

Primary Crushing - Mineral Processing & Metallurgy

The term “primary crusher,” by definition, might embrace any type and size of crushing machine. The term implies that at least two stages of crushing are involved, but in many cases the machine which performs the function of initial crusher is the only crusher in the plant. The factors influencing the selection of a crusher for this service are much the same, regardless of how many .

Estimation of Uniaxial Compressive Strength of Coal

The uniaxial unconfined compressive strength (UCS) is an important mechanical property of the rock mass having several implications in planning and de signing both underground and opencast coal mines. UCS is usually determined on core samples obtained fr om exploratory boreholes and tested either in the field or preferably in the laboratory.

Compressive strength of rocks - PetroWiki

 · Estimating compressive strength. General rock failure criterion can be reduced to a few parameters dependent on lithology (m) and the uniaxial compressive strength (C 0).Lithology is commonly derived during log analysis, so m may be estimated (Table 1).What is needed still is an initial measure of rock strength provided by C 0. C 0 can be estimated from porosity or sonic velocities, but …

Jaw Crushers - Parker Plant

Rocksizer Jaw Crushers. RockSizer primary stage jaw crushers feature the upthrust toggle action which is also common to the StoneSizer range. Developed by Parker, this gives a slight downward movement to the swing jaw that promotes a forced feed and therefore increased output while at the same time minimising any rubbing action resulting in a well shaped product and reduced and even wear on .

Crushers - QueensMineDesignWiki

In any operation that incorporates size reduction, selecting the primary crusher is vital to the overall success. The main parameters to first decide on a general type of crusher are the impact strength, product size and material hardness. The final design for a crusher will be selected primarily based on required capacity, feed and product size.

compressive strength of rock calculation

The Point Load Test, also known as the Point Load Strength Index Test, is used to calculate the rock strength index of a rock specimen. From the rock strength index, other rock parameters, such as the uniaxial compressive strength, can be estimated.This test is very economical due to the simplicity of the apparatus and the .
