energy savings in coal crusher
Energy consumption in open-pit mining operations
Potentials for energy saving in transportation for mining iron, copper, and coal. According to Section 2, most mines currently use the trucks for the haulage of minerals. Also, trucks consume a large amount of energy in mining. The replacement with the IPCC systems is one way to reduce the energy consumption in this sector.

Optimal energy management for a jaw crushing process in deep mines
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 the energy cost to be minimized by accounting for the time-of-use electricity tariff. The first model is referred to as a variable load-based optimal control ...

Comparison of breakage behavior between the sieving crusher …
The −50 mm particles in the feed are removed by hand sieving and +50 mm particles are broken by DTRC. As a comparison, raw coal without any pretreatment is fed to a SC. Results indicate that the decrease of coal mass to DTRC can reduce the consumed breakage time and energy, but products of SC have a higher yield of −50 + 6 mm particles.
