Introduction Comminution processes have always been characterized by low efficiency rates. This is mainly because for this kind of process it has traditionally Many types of Jaw crushers exist in the current market differing to a large extent by component assembly, area of application (size), and model of design Optimal energy management for a jaw crushing process in

Level comminution process for brittle materials generally use impact principle with beat and crazy [13]. First-degree communion process of the crusher, the size of the material is centered betweenOver the last few decades, the demand for energy-efficient mineral-processing methods has continued. The necessity to develop energy-efficient technologies for the mineral industry will increase in the future, considering the exhaustion of high-quality resources and severe environmental limitations. The subject of this study is crushing Modeling and Improving the Efficiency of Crushing Equipment

scale jaw crusher, whose technical properties are listed in Table 2. Eliminating the flakiness effect on the rock crushability was based on the use of an 8 mm bar sieve.1. Jaw crushers The jaw crusher is V shaped consisting of two jaws one movable and the other fixed making an angle of 10-20 ° between them. The materials for size reduction are introduced between the two jaws at the top and compressive force is exerted by the movable jaw. The size reduction happens from top to bottom with largerInternational Journal of ChemTech Research

There are lots of different kinds of crushers from jaw crushers to impactors and cone crushers. Crushing is an versatile process and the kind of crusher you need depends on the 'stage' of crushing. The three main stages of crushing are primary, secondary, and tertiary all of which have their own unique benefits.The Discrete Element Method (DEM) is a numerical method that is able to simulate the mechanical behavior of bulk solids flow using spheres or polyhedral elements, offering a powerful tool for equipment design and optimization through modeling and simulation. The present work uses a Particle Replacement Model (PRM) embedded in Minerals Free Full-Text DEM Simulation of Laboratory-Scale Jaw

Abstract. In this study, an analytical perspective is used to develop a fundamental model of a jaw crusher. Previously, jaw crushers were modelled in regard to certain aspects, for example, energy consumption (Legendre and Zevenhoven, 2014) or kinematics (Oduori et al., 2015). Approaches to date have been mainly property specific.The double jaw crusher is designed for crushing hard materials, also quarried materials, sand and gravel, and recycling.

Abstract. This paper develops two optimal control models for the energy management of a mining crushing process based on jaw crushers. The performance index for both models is defined as theThe results show that an external diameter/offset ratio within the average of 10:1 can be considered for the offset calculation of a jaw-type crusher shaft. The outcome of the result was used to redesign and develop a prototype crushing machine with better output crushing pressure of 13.1×10 5 kN/m 2 and capable of crushing 425–569 kg ofPerformance optimization of jaw-type rock crushing

The main reason for this inefficiency is in the random distribution of forces on the particles inside the crusher. With certain simplifications, the theoretical energy efficiency of comminution can be estimated to fall between 5 and 10 % (Legendre & Zevenhoven, 2014) while the measured energy efficiency in actual comminution testing Particle size distribution curves of recycled aggregates from building demolition concrete crushed by jaw and impact crushers. The jaw crusher produced 60% of coarse aggregates in weight, whereas the impact crusher produced 49% coarse aggregates. The proportion of particles finer than 0.15 mm is around 7–8% weight for both crushing Concrete aggregates properties crushed by jaw and
