Particle crushing underpins important macroscopic behaviour of granular materials such as yielding, deformation, dilatancy, failure, mobility and packing features. The crushing condition and crushing pattern have commonly been examined for particles subjected to uniaxial loadings. In the real engineering context, a sand grain is typically in …

The mechanical behavior and particle breakage of carbonate sand under a simple shear condition are a concern for many engineers. In this study, simple shear tests were carried out under constant-load and constant-volume conditions, and various combinations of relative density and vertical consolidation stress were considered.

Lightweight expanded clay aggregate (LECA) is a lightweight granular material, which can be used as an ideal backfilling geomaterial attributed to its porous particles. Through X-ray tomography images, it is found that LECA particle is a porous composite particle with a strong shell and a fragile core, originating from the sintering …

The results show that the incorporation of standard sand reduces the shear strength of coral sand, and the effect is most apparent when the 0.3–0.5 mm particles are replaced. As the water content increases, the cohesion of the coral sand mixture decreases, whereas the internal friction angle first increases and then decreases.

The elastic modulus, yielding strength and crushing strength of circular, branched and flaky coral sand particles were determined by compression tests and statistical analysis. The correlations between particle strength and particle size was clarified, which provided parameter basis for studying the mechanical properties of coral sand.

If you have a need to process sand, gravel, or rock and you do not own the proper rock-crushing equipment, you need to work with a professional company that sells the best new machines for your needs.

Cone Crushers are compression-type crushers that are typically found in secondary crushing stages but can be used as the primary crusher in certain applications. They handle medium hard to very hard, abrasive materials that can be dry or wet but not sticky. Cone Crushers are typically found in quarried materials and sand and gravel applications.

The concept of critical state has been a cornerstone of modern critical state soil mechanics. It remains inconclusive how grain crushing affects critical state behavior in crushable granular sand. A multiscale computational approach is employed in this study to simulate the shearing behavior of crushable granular sand at critical state. Grain …

Our rotor impact mill (type RPM) and rotor centrifugal crusher (type RSMX) crushing systems ensure best results in the production of crushed sand. Both machines operate based on the impact principle and have a rotor with a vertical shaft. This enables you to achieve high sand yields and the desired cubic particle shape.

Calcareous sediments generally consist of the remains of marine organism,which tend to be crushed relatively easily under load,compared to terrigenous materials. Laboratory tests are carried out on calcareous sand taken from the South China Sea;and it is pointed out that the compression behavior of calcareous sand under one-dimensional compression is …

The particle crushing of calcareous sand was investigated by Wu et al. 14, and found that excessive deformation and foundation failure occur as a result of particle breakage.

This waste can also be harmful. This study focuses on making a machine that can recycle glass waste into constructional sand, that is, a glass-crushing machine. Recycling glass waste as an alternative to constructional sand will lessen the solid waste problem, decrease the market price of constructional sand, and increase its …

The amount of particle crushing for calcareous sand increases with increasing density and confining stress. Compared with the undrained condition, a larger amount of particle crushing of calcareous sands is observed in the drained triaxial compression test.
