Since September, high coal costs and inflexible electricity prices have caused shortages that forced local governments to implement rolling blackouts for energy-intensive industries. The shortages made national news when, starting Sept. 23, they became so "severe" that power to residential areas was cut unannounced to prevent the grid from ...

1. Introduction. Breakage of minerals is an energy intensive process. Energy for the comminution of raw coal in power plants consumes nearly 0.5–1% of the gross power generation (Shi et al., 2015).This proportion would increase to over 55% in the mineral processing plant (Narayanan, 1987).In this case, selection of alternative grinding devices is mainly based on the energy saving.

It pulverizes coal by applying hydraulically-loaded grinding pressure through three grin- ding rollers onto a rotating bed of coal. Grinding pressure can be adjusted to account for variations in coal grindability and desired product fineness. Raw coal is fed through a centrally located feed pipe to the center of the grinding table.
