Power Consumption of Gyratory and Cone Crushers. To compute the power consumption of gyratory crushers, knowledge of the ore work index and crusher capacity is necessary. In its simplest form, the power consumption is given by (5.5) P = W i Q F 80 − P 80 F 80 100 P 80 where P = power (kW) W i = work index (kWh/t) Q = capacity (t/h)Crushing is one of the most energy-consuming technological processes. The purpose of grinding is to achieve the desired grain size of mineral raw materials. The process of grinding consists of many factors, for example, the size and form of crushed grains, as well as their mutual arrangement inside the crushing machine chamber, the Influence of Natural Aggregate Crushing Process on Crushing

About 2% of the electricity produced in the whole world is used during the grinding process of raw materials [1]. While total electrical energy consumption for cement production is about 100 kWh/ton of cement, roughly two thirds are used for particle size reduction [2]. About 65% of the total electrical energy used in a cement plant is utilized1. Introduction. With the development of the world economy and the increasing population, the demand for mineral resources is increasing. Iron is no exception, as an important material, it is widely used in construction, manufacturing, and transportation, such as China's iron ore resource consumption has exceeded 1.2 billion tons [1].The Simulation and optimization of crushing chamber of gyratory crusher
