Highfrequency vibrating screens are the most important screening machines primarily utilised in the mineral processing industry. They are used to separate feeds containing solid and crushed ores down to approximately 200 μm in size, and are applicable to both perfectly wetted and dried feed. The frequency of the screen is mainly controlled by an electromagnetic vibrator which is mounted ...

· Coal accounted for 37% of electricity sold on Chile's main SEN grid in March, up from 27% five months earlier, while hydropower fell from 47% to 22% over the same period. However, compared to previous years, 2019 has seen gasfired power plants take more market shares to coal's detriment, thanks to cheaper supplies from neighboring Argentina.

· Electricity demand has doubled since 2000 and is set to double again by 2050. Twothirds of Chile's energy is imported: of oil, 80% of natural gas and 80% of coal (its second largest coal supplier being Australia). More than 90% of coal used in the country is for electricity generation. Firewood accounts for about 60% of domestic energy ...
