The crushability of rocks depends mainly on the crusher type and properties, and geological characteristics of rocks. Physico-mechanical properties, mineralogical and textural features, structural
Apr 15, 2014· The simulation results show that due to the high no-load power consumption of the jaw crusher, the optimal switching control of the jaw crushing process can achieve considerable energy saving and cost saving as compared to the variable load-based optimal control. However, switching the jaw crusher will result in severe impact in practice.
Rock texture is a term representing the mineral grains, grain sizes, and matrices of rocks. Crushability properties of rocks are very important parameters on an industrial scale and they can be determined by different methods. This study investigated the effects of textural properties of rocks on their crushability. For this purpose, some physical and mechanical tests were carried out on 12
Apr 01, 2015· 5. Jaw crusher. Jaw crushers are often used for primary crushing of hard or abrasive run of mine ore at the start of a crushing circuit in order to provide size reduction sufficient for further crushing stages. The crusher consists of two sets of jaws, one jaw being fixed and the other moving back and forth in an eccentric cyclic motion.
As the PF300 is able to be operated with sizers, roll crushers or hybrids and has excellent technical properties, the system will be primarily marketed for use in the coal, overburden and oil sands but may also be able to process harder materials, depending on the compressive strength of the material, product size and suitability for crushing
Nov 01, 2014· To compare the effect of the pre-weakening on crushability of phosphate ore, the standard Bond test was used. Twenty pieces of rock in a size range of 5–7.5 cm from the crushing plant’s average feed were prepared and two energy levels of 3
One study showed that a yield increase of 2.5-4.5% was possible without significant additional generation of fines b 0.5 mm [19]. In fact, the liberation of coal is controlled by many factors and
Comparison between bond crushing energy and Know More. For predicting the energy consumption during the size-reduction process, the Bond crushing energy and work done by the jaw crusher for rocks. It appears that the crushability index of limestone, 12.8 kWh/tonne, the Bond crushing energy...
altering the fundamental property of the coal (Sahoo et al., 2007). The effect of MW treatment on coal was also described by Marland et al. (2000). According to author, depending upon the microstructure and geological properties, coals naturally contain water to varying degrees and water is considered to be a good absorber of MW energy. When
July, 2008: The first mobile crushing plant was put on the market, which marked the new level of manufacturing crushers and grinding mills. 2007-2006 December, 2007: The sales of the company were more than 350,000,000RMB.
