and operating modes. This creates the prerequisites both for using specific electrical energy costs as a control criterion and for the use a controlled electric drive to achieve maximum energy savings. The most important result is that the operating modes of grinding machines could be established by more efficient use of electrical energy.
As experience shows, when one determines the energy-power parameters of crushing and grinding processes by using the existing methods, the power of motors used in drives of existing crushers of various types often …
It was revealed that the greatest energy consumption during the operation of crushers goes into the kinetic energy of the crushing plates and the potential energy of deformation of the springs.
Energy consumption for crushing various materials makes up a large share (up to 5%) in the energy balance of the world. Many industrial industries, including mining, process large quantities of bulk materials of various size classes. In most cases, the required size is achieved by crushing the pieces into fragments in crushers [1].
Abstract: This paper presents experimental comparison of two machine crushing technologies: one-stage and two-stage. The study was carried on a model double-toggle jaw crusher which allows crushing forces, energy and toggle displacement to be measured.

Low Energy Consumption: Another important feature of jaw crusher design is its low energy consumption. Jaw crushers are designed to be efficient machines that consume less energy than other types of crushers, …
It is well known and taken for granted that the efficiency of energy use by comminution (i.e. breaking, crushing, grinding) equipment is very low, typically less than 10%. Most of the process input power is dissipated as heat and noise and ineffective deformation of the material to be processed and the device itself.
Since machine tools are used extensively throughout their functional life and consequently consuming valuable natural resources and emitting harmful pollutants during this time, this study reviews strategies for characterizing and reducing the energy consumption of...

The energy consumption during crushing depends on factors such as the hardness and abrasiveness of the material, the crusher's efficiency, and the desired output size. Auxiliary Equipment Auxiliary equipment, including conveyors for material transport, screens for sizing and separating aggregates, and hydraulic systems for crusher adjustment ...
Using statistical analysis of the influence of individual mechanical properties we found that the greatest influence on energy consumption for crushing was compressive strength.
More than 3 billion tonnes of raw materials are crushed every year. More than 70 billion kWh of electricity is consumed, representing up to 5% of the country's total production. For a single mine, the share of energy consumption for crushing can be …
This, in turn, allows the user to ind the range of operating parameters that cause the least energy consumption. The Bond (1952) equation is used to scale the energy consumption in crushing. But the energy required to crush a ton of material differs from machine to machine.
Analysis of Energy Consumption of Crushing Processes –... This paper presents experimental comparison of two machine crushing technologies: one-stage and two-stage.
