primary crushing plant on solid rock reduces the cost of concrete and structural steel. Life of Mine/Expansion Plans The life of the mine is a key element in the design of any crushing plant. Short-term mine lives (three to eight years) require a very careful approach to design, layout and construction. Since the
As illustrated in Fig. 5, the gradation curve of weathered phyllite fills with 75% rock content is at the bottom, while that of weathered phyllite fills with 35% rock content is at the top. Fig. 5 shows that the larger the rock content, the coarser the particle in the weathered phyllite fills. In addition, the coefficients of uniformity (C U) of the five groups …

The crack closure effect of rock materials plays a key role in the evaluation of its compressive mechanical behavior. Based on the effective medium theory, an exponential model is proposed to describe the influence of the crack closure effect on the constitutive relation. The crack deformation is characterized by natural strain, and the …

This research includes optimization of aggregate production of the stone crushing plant using fuzzy modelling. The investigation includes onsite aggregate testing and fuzzy logic implementation. Fuzzy modelling is a type of computerized reasoning used to simulate the real plant operation. In this work, a lot of agent degree information for …
The test determines the Bond Impact Work Index which is used with Bond's Third Theory of Comminution to calculate net power requirements when sizing crushers*. It is also used to determine the required open-side settings (jaw crushers and gyratory crushers) or closed-side settings (cone crushers) for a given product size.P80 = 25400 x …
Fragmentation of granite cylinders having a centric charge with different decoupling ratios was investigated in blast experiments. Conclusions are made from studying the post-blast specimens and strain measurement. Eight blasting tests were carried out on granite cylinders having a diameter of 240 mm and a length of 300 mm. …

The degree of crushing blocks during open-air blasting is the primary measurement standard for comprehensive costs such as drilling, shoveling, transportation, and follow-up processes. Powder factor is the primary influencing factor and is typically used in blasting model tests to perform related research. However, high costs, test …
As aforementioned, the rock crushing strength from UCS test ranged from 22 MPa to 46 MPa due to the random internal flaws and discontinuities in the natural rock. To study the effect of rock crushing strength, the lowest and highest rock crushing strengths of 20 MPa and 50 MPa were adopted to carry out the numerical parametric study.

Crushing is a size reduction process that plays a key role in both mineral processing and crushing–screening plant design. Investigations on rock crushability have become an important issue in mining operations and the manufacture of industrial crusher equipment. The main objective of this research is to quantify the crushability of hard …
productively dig the blasted rock, and the amount of oversize chunks produced. Now, more consideration is given to the effect of blasting on operations beyond loading, such as crushing and grinding. There are two important aspects of blasting on fragmentation; one is seen and one is unseen. The first is the size distribution of blasted fragments.
As a new technique, the ultrasonic vibration rock crushing method possesses huge advantages and potentials in improving the hard rock crushing efficiency. We have directly applied the ultrasonic vibration to rocks via the ultrasonic transducer and performed the macroscopic observation on the variation of rocks' compressive strength via the …
